Azure -900 - 2 Flashcards

Question

In which type of cloud model are all the hardware resources owned by a third-party and shared between multiple tenants? Options: A. Private B. Hybrid C. Public

Answer 1

✅ Answer: C. Public 🧠 Explanation: In a public cloud, like Microsoft Azure, Amazon Web Services (AWS), or Google Cloud Platform (GCP): The cloud provider (third-party) owns and manages all hardware, software, and infrastructure. Multiple customers (tenants) share these resources securely. Customers only pay for what they use (pay-as-you-go), and do not manage or maintain the infrastructure.

Answer 2

✅ Answer: A. Hybrid 🧠 Explanation: A hybrid cloud connects public cloud resources (like an Azure web app) with on-premises infrastructure (such as a Microsoft SQL Server hosted in your datacenter). This setup allows applications to interact across environments, combining the scalability of the cloud with the control of local infrastructure.

Answer 3

✅ Answer: A. Operational (OpEx) 💡 Explanation: Azure's pay-as-you-go model falls under Operational Expenditure (OpEx). You don't invest upfront in physical infrastructure (like servers); instead, you pay monthly or as-used. Ideal for businesses wanting cost flexibility and scalability without large capital investment. ❌ Why the Others Are Incorrect: B. Elastic – Elasticity is a cloud characteristic, not a financial model. It refers to the system’s ability to automatically scale resources up or down based on demand. C. Capital – Capital Expenditure (CapEx) is when you purchase hardware or infrastructure upfront, like buying and setting up servers on-premises. Azure's pay-as-you-go model avoids this. D. Scalable – Like elasticity, scalability is a technical benefit, not a cost model. It means a system can grow to meet higher demand.

Answer 4

✅ Answer: B. Fault Tolerance ℹ️ Explanation: Fault tolerance ensures continuous service availability by using redundant components. If one component fails, others continue serving without disruption.

Answer 5

✅ Answer: A. Disaster Recovery ℹ️ Explanation: Disaster recovery is about restoring services and data after an outage or failure, such as restoring a VM backup or failing over to another region.

Answer 6

✅ Answer: D. Dynamic Scalability ℹ️ Explanation: Dynamic scalability enables automatic allocation of resources to handle increased demand without manual intervention, improving performance under load.

Answer 7

✅ Answer: A. Low Latency ℹ️ Explanation: Low latency means faster response times for end-users. It reduces delays when accessing apps or data over the internet, improving user experience.

Answer 8

Answer: Yes Analysis: A hybrid cloud combines a private cloud (which often utilizes an internal network or on-premises infrastructure) with a public cloud. Without an internal network or on-premises component, it would simply be a public cloud deployment, not a hybrid one.

Answer 9

✅ Answer: A. Yes ℹ️ Explanation: This is one of the main benefits of hybrid cloud — to burst into public cloud resources when local capacity is not sufficient.

Answer 10

✅ Answer: B. No ℹ️ Explanation: Public cloud resources can be accessed by any authorized user, not just guests. Access is controlled through identity systems like Azure AD, not user type.

Answer 11

✅ Answer: B. No ℹ️ Explanation: PaaS abstracts the underlying OS — you don’t manage or control the operating system or infrastructure. That's the provider's responsibility.

Answer 12

✅ Answer: A. Yes ℹ️ Explanation: You can scale app resources (like memory or CPU) by selecting higher pricing tiers in most PaaS offerings like Azure App Service.

Answer 13

✅ Answer: A. Yes ℹ️ Explanation: PaaS platforms support autoscaling, which allows you to automatically increase or decrease instances based on demand or custom rules.

Answer 14

✅ Correct Answers: A. Replacing failed server hardware C. Managing physical server security 📝 Explanation: ✅ A. Replacing failed server hardware → In Azure, Microsoft manages the underlying physical infrastructure. You don’t worry about physical hardware failures. ✅ C. Managing physical server security → Security of Azure data centers and physical servers is Microsoft’s responsibility (shared responsibility model). ❌ B. Backing up application data → You are responsible for backing up your own application data inside the VM. ❌ D. Updating server operating systems → You manage the guest OS in IaaS (Infrastructure as a Service) like Azure VMs. ❌ E. Managing permissions to shared documents → You still control and manage file/folder permissions within your VMs.

Answer 15

B. False Explanation: Pay-As-You-Go is Operational Expenditure (OpEx) — you pay only for what you use, with no upfront capital investment. CapEx would involve purchasing hardware or infrastructure upfront.

Answer 16

A. True Explanation: Building or setting up your own datacenter involves Capital Expenditure (CapEx) — you make a significant upfront investment in hardware, facilities, and infrastructure.

Answer 17

B. an Azure virtual machine Explanation: Azure Virtual Machines provide raw computing infrastructure that you can configure, control, and manage — making them a classic Infrastructure as a Service (IaaS) offering. The others (web app, logic app, SQL database) are managed services and fall under Platform as a Service (PaaS).

Answer 18

A. private cloud and hybrid cloud only Explanation: Physical servers can be deployed in private clouds, which are hosted on-premises, and in hybrid clouds, which combine on-premises (where physical servers can exist) with public cloud resources. You cannot deploy physical servers in a public cloud, as the infrastructure is owned and managed by the cloud provider (e.g., Microsoft, AWS).

Answer 19

✅ Answer: Public Cloud → C. No required capital expenditure Private Cloud → A. Provides complete control over security Hybrid Cloud → B. Provides a choice to use on-premises or cloud-based resources Explanation: Public Cloud resources are owned by providers like Microsoft or AWS, so you only pay for what you use — no upfront hardware cost. Private Cloud is hosted on-premises, giving full control over security configurations. Hybrid Cloud blends on-premises infrastructure with cloud resources, allowing flexibility in deployment.

Answer 20

No ➤ You cannot extend a private cloud by adding physical servers to the public cloud. You extend it by adding virtual resources (like VMs) in the public cloud, forming a hybrid cloud.

Answer 21

✅ Yes ➤ A hybrid cloud is a mix of on-premises/private cloud and public cloud resources. You must deploy resources to the public cloud to form it.

Answer 22

No ➤ A private cloud can be connected to the internet. What defines it is that it is owned and operated by a single organization—not its disconnection from the internet.

Answer 23

✅ Answer: A. Hybrid Explanation: A hybrid cloud combines on-premises infrastructure (private cloud) with public cloud services (like Azure). Since both environments are connected and working together, this setup qualifies as a hybrid model. B. Private – Incorrect: Only on-premises/cloud hosted by the organization itself. C. Public – Incorrect: Only includes cloud services from providers like Azure without any on-premises integration.

Answer 24

Answer: B. False PaaS abstracts the infrastructure layer. You don’t get access to the OS or VM directly — Microsoft manages that.

Answer 25

Answer: A. True Azure App Service (a PaaS offering) supports scaling memory and other resources by switching to a higher pricing tier.

Answer 26

Answer: A. True Azure PaaS supports autoscaling based on load, which automatically increases/decreases the number of instances.

Answer 27

✅ Answer: B. No 💡 Explanation: Azure Virtual Machines are IaaS (Infrastructure as a Service), not PaaS. Azure SQL Database is PaaS. Azure Storage Accounts are typically Storage services and fall under PaaS or foundational services, but not exclusively PaaS depending on use. Since virtual machines are part of the solution and they are IaaS, this violates the requirement of using only PaaS. Therefore, the goal is not met.

Answer 28

✅ Answer: C. Infrastructure as a Service (IaaS) 💡 Explanation: IaaS provides virtual machines, networking, and storage, allowing full control to install, configure, and manage custom apps and their prerequisites. A. SaaS is for using ready-made apps (e.g., email, CRM); you can't install your own. B. PaaS provides a managed app hosting environment, but doesn't allow deep control to install custom prerequisites or third-party services. 📌 Since you need to deploy and configure multiple custom applications and supporting services, IaaS is the correct model.

Answer 29

B. No Explanation: Building a data center involves a large upfront cost for hardware and infrastructure, so it is Capital Expenditure (CapEx), not OpEx.

Answer 30

A. Yes Explanation: Salaries are recurring operational costs and fall under Operational Expenditure (OpEx).

Answer 31

A. Yes Explanation: Leasing software involves ongoing payments, which makes it an OpEx. One-time software purchases would be CapEx.

Answer 32

✅ A. Platform as a Service (PaaS) Explanation: Azure Cosmos DB is a fully managed NoSQL database service designed for high availability and global distribution. Since Microsoft manages the infrastructure and provides the platform for developers to build applications without worrying about the backend, it falls under PaaS.

Answer 33

B. No Explanation: Azure does not support nested resource groups. Each resource group exists independently.

Answer 34

B. No Explanation: Each Azure VM belongs to only one resource group. You cannot assign a single VM to multiple groups.

Answer 35

A. Yes Explanation: A resource group can contain resources from different regions. Resource groups are not limited by region, only the resources themselves are.

Answer 36

B. No Explanation: When you install Microsoft SQL Server on an Azure VM, you are managing both the infrastructure and the SQL Server. This is Infrastructure as a Service (IaaS), not PaaS.

Answer 37

A. Yes Explanation: Azure SQL Database is fully managed by Microsoft. You don’t manage the OS or SQL Server engine, so it's considered PaaS.

Answer 38

B. No Explanation: Azure Cosmos DB is a PaaS offering, not SaaS. You use it to build applications, but you're not just consuming end-user software—you’re managing the data and integration.

Answer 39

✅ Answer: C. Platform as a Service (PaaS) 📝 Explanation: When Azure manages the infrastructure, operating system, and SQL Server updates, such as with Azure SQL Database or Azure SQL Managed Instance, it's considered PaaS. You only manage data and app logic, not the server or database engine. 💡 If you install Microsoft SQL Server on a VM, it’s IaaS because you manage the OS and SQL Server.

Answer 40

✅ Answer: C. An Azure App Service and Azure SQL databases 📝 Explanation: Azure App Service is a PaaS solution for hosting web apps. Azure SQL Database is a managed relational database service (PaaS). Both services are fully managed by Azure, aligning with the PaaS-only requirement. ❌ Options A, B, and D include virtual machines (VMs), which are IaaS, not PaaS.

Answer 41

✅ Answer: A. Application data 📝 Explanation: In a SaaS model: The cloud provider manages everything — infrastructure, operating systems, middleware, application software, and storage. The customer only provides and manages their data (i.e., content or usage data within the application, eg : The spreadsheets and numbers you input and save.). Common examples: Microsoft 365, Salesforce, Google Workspace.

Answer 42

Answer: A. Yes Explanation: Azure Files provides shared storage accessible via SMB protocol. It is a managed file share but still considered an IaaS solution because you are not managing the OS, but you're managing the file share as a resource. Azure Files is IaaS because you manage how the storage is used, even though Azure handles the underlying hardware and OS.

Answer 43

*** Answer: B. No Explanation: Running a DNS server on a VM is IaaS. You manage the OS and DNS configuration. PaaS abstracts infrastructure and OS management, which is not the case here.

Answer 44

Answer: A. Yes Explanation: Microsoft Intune is a SaaS solution that provides cloud-based device and app management. You use it via a web portal without managing any infrastructure.

Answer 45

✅ Answer: A. Yes Explanation: Elastic scalability means cloud resources can automatically scale up or down based on demand. Cloud computing supports this through features like auto-scaling in Azure or AWS.

Answer 46

✅ Answer: A. Yes Explanation: Public cloud providers own the infrastructure, so customers don't have to invest in hardware. This shifts expenses from CapEx (upfront costs) to OpEx (pay-as-you-go).

Answer 47

✅ Answer: A. Yes Explanation: Cloud platforms use virtualization to share physical resources among multiple tenants securely and efficiently. This enables multi-tenancy.

Answer 48

✅ Answer: C. To the same resource group Explanation: A resource group in Azure is a logical container for resources. Assigning permissions to a resource group automatically applies those permissions to all the resources inside it, including multiple virtual machines. This simplifies permission delegation and access control. Delegation in the context of cloud computing (like Azure) means assigning specific permissions or responsibilities to another user or group

Answer 49

Answer: A. Yes Explanation: Deploying Azure virtual machines to two or more availability zones provides fault isolation and high availability. Each Availability Zone is a separate physical location within a region, so if one data center fails, the other zones can continue to run your services.

Answer 50

Answer: A. No change is needed Explanation: Azure SQL Data Warehouse (now called Azure Synapse Analytics) offers built-in high availability by default. It distributes data and computing resources across multiple nodes, allowing it to continue operating even if some components fail. Azure Data Warehouse (now known as Azure Synapse Analytics) is a PaaS offering from Microsoft. As with all PaaS services from Microsoft, SQL Data Warehouse offers an availability SLA of 99.9%. but for VMs and some PaaS services: You need to manually select Availability Zones for zonal redundancy.

Answer 51

✅ Answer: A. Yes 💡 Explanation: Deploying VMs across two or more regions means they are hosted in separate geographic locations with independent data centers. This provides geo-redundancy, ensuring that if one data center (or even a whole region) goes down, the others can continue running, thereby achieving high availability. While Availability Zones within a single region provide fault tolerance across datacenters, multi-region deployment adds an extra layer of resilience against region-wide failures.

Answer 52

✅ Answer: B. No 💡 Explanation: Azure resources can access other resources across different resource groups. Resource groups are mainly for organizing and managing permissions, not limiting connectivity.

Answer 53

✅ Answer: A. Yes 💡 Explanation: Deleting a resource group in Azure automatically deletes all resources within it. This is useful for managing and removing environments like test setups.

Answer 54

✅ Answer: A. Yes 💡 Explanation: Resource groups are region-independent containers. You can place resources from multiple regions within the same resource group.

Answer 55

✅ Answer: A. Azure Data Lake C. Azure SQL Data Warehouse 💡 Explanation: Azure Data Lake: Ideal for storing large volumes of structured and unstructured data. It integrates easily with Power BI and supports big data analytics. Azure SQL Data Warehouse (now part of Azure Synapse Analytics): A scalable analytics service perfect for querying and visualizing large datasets using Power BI. Other options like Cosmos DB, SQL Database, or PostgreSQL aren't cost-effective or optimized for large-scale analytical workloads accessed infrequently.

Answer 56

✅ Answer: B. https://portal.azure.com Explanation: The Azure Portal is the central web-based interface provided by Microsoft for managing all Azure services. From this portal, you can monitor, configure, and control everything from web apps to virtual machines and storage accounts. The correct URL for accessing the Azure portal is: https://portal.azure.com

Answer 57

D. an Azure data center failure ✅ Correct – Availability Zones are designed to protect against data center-level failures within a region. A zone is more than just a copy — it’s a complete, isolated infrastructure unit (datacenter) inside an Azure region, designed to prevent service disruption in case of localized failures. A. a physical server failure ❌ Incorrect – Handled by Azure's underlying platform or Availability Sets, not necessarily Availability Zones. B. an Azure region failure ❌ Incorrect – Region-wide failures require geo-redundant solutions (e.g., paired regions), not Availability Zones. C. a storage failure ❌ Incorrect – Storage redundancy (e.g., LRS, GRS) protects against storage failures, not Availability Zones specifically.

Answer 58

Answer: C. Local Network Gateway A. NAT Gateway ▪ Used for outbound internet connectivity for Azure resources ❌ Not used for defining VPN appliances B. Application Gateway ▪ Acts as a load balancer and web traffic manager (Layer 7) ❌ Designed for HTTP/S traffic, not VPN connections ✅ C. Local Network Gateway ▪ Represents your on-prem VPN appliance in Azure ▪ You define its public IP and address range ✅ Correct choice for defining a VPN device D. Virtual Network Gateway ▪ Azure-side gateway that terminates the VPN tunnel ❌ Needed to complete the connection, but not to define the on-prem VPN appliance E. On-premises Data Gateway ▪ Lets services like Power BI access on-prem data ❌ Not used for network-level VPN connectivity F. Azure Data Box Gateway ▪ Transfers large data sets to Azure ❌ Used for data ingestion, not VPNs G. Azure Stack Edge ▪ Hybrid cloud appliance for edge computing and data transfer ❌ Not involved in VPN configuration H. Web Application Firewall policies ▪ Protects web apps from attacks like SQL injection and XSS ❌ Has nothing to do with VPN setups

Answer 59

✅ Correct Answer: B. No 💡 Explanation: Resource groups are logical containers used to organize and manage Azure resources. However, they do not provide physical isolation or failover protection. Even if VMs are placed in different resource groups, they can still reside in the same data center. To achieve high availability against a data center failure, you must deploy VMs to multiple Availability Zones, which are physically separate locations within an Azure region

Answer 60

✅ Answer: B. No Explanation: While Azure Virtual Machine Scale Sets improve availability and support autoscaling, they do not guarantee availability across multiple data centers (which is required for protection against a single data center failure) unless specifically configured with Availability Zones.

Answer 61

Answer: B. No Explanation: An Azure subscription can only be associated with one Azure AD tenant at a time. However, a single Azure AD tenant can have multiple subscriptions.

Answer 62

Answer: A. Yes Explanation: It is possible to change the Azure AD tenant associated with a subscription, though this may involve manual steps and potential limitations (e.g., not all resources can be transferred).

Answer 63

Answer: B. No Explanation: If a subscription expires, access to its resources is lost, but the Azure AD tenant is not deleted. It remains and can be managed using a different subscription.

Answer 64

Answer: C. Azure policies Explanation: Azure Policies are specifically designed to manage and enforce compliance across your Azure environment. They enable you to define rules (such as allowed VM SKUs or locations), and apply them to resources, resource groups, or entire subscriptions—even across multiple subscriptions using management groups. Why others are incorrect: A. Resource groups only organize resources within a single subscription. B. Management groups help organize subscriptions, but they don’t enforce compliance rules. D. App Service plans relate only to hosting web apps—not compliance or policy control.

Answer 65

Answer: ✅ A. multiple subscriptions ✅ D. multiple resource groups Explanation: A. Multiple subscriptions – Subscriptions provide isolated billing, quotas, and role-based access control. Each department can have its own subscription, making it easier to delegate control and track costs. ✅ D. Multiple resource groups – Resource groups allow logical grouping of related resources. You can apply role-based access so that each department admin only manages their assigned group. ✅ Why others are incorrect: B. Multiple Azure AD directories – Azure AD tenants are used for identity, not resource segmentation. Managing multiple tenants is complex and unnecessary here. ❌ C. Multiple regions – Regions relate to physical location and redundancy, not administrative boundaries or resource ownership. ❌

Answer 66

✅ Answer: A. Yes 🧠 Explanation: A Microsoft account (or Azure AD identity) can manage multiple Azure subscriptions. This is useful for scenarios like separating environments (e.g., dev/test/prod) or teams.

Answer 67

✅ Answer: B. No 🧠 Explanation: Azure doesn't support merging subscriptions. However, individual resources can be moved between subscriptions, and billing ownership can be transferred.

Answer 68

✅ Answer: A. Yes 🧠 Explanation: A company can operate across multiple subscriptions to isolate workloads, apply different policies, or meet compliance needs. However, a single resource exists in only one subscription.

Answer 69

✅Answer: B. The virtual machines can be moved to the new subscription. 💡Explanation: Azure allows you to move virtual machines (and their associated resources) to a different subscription using the Azure portal, PowerShell, or CLI. ❌ Why other options are incorrect: "The virtual machines cannot be moved" → Incorrect, VMs can be moved across subscriptions. "Only if they are in the same resource group" → Not required; you can move from any resource group. "Only if they run Windows Server 2016" → OS version has no impact on the move capability.

Answer 70

✅Answer: A. a virtual network gateway E. a gateway subnet 💡Explanation: To connect your on-premises network with Azure VMs, you need a site-to-site VPN: A. Virtual Network Gateway: This is the Azure VPN device that provides the tunnel to your on-premises VPN device. E. Gateway Subnet: This is a dedicated subnet (GatewaySubnet) within your virtual network where the virtual network gateway is deployed. D. Virtual Network: This is required, but the question implies that the VMs already exist—so the virtual network is already in place. B & C (Load Balancer / Application Gateway): These are used for distributing traffic to VMs but not for establishing connectivity between on-prem and Azure.

Answer 71

✅ D. Create a new support request Explanation: Azure imposes default quota limits on resources (like CPU cores, managed SQL instances) to help control cost and capacity planning. If you hit one of these limits, you can request a quota increase by creating a support request in the Azure portal. Go to Help + support > New support request Choose Issue type: Service and subscription limits (quotas) Then select the resource type you want to increase (e.g., SQL Database Managed Instance) Why other options are incorrect: ❌ A. Service health alert: Monitors service availability issues—not used to increase quotas. ❌ B. Upgrade your support plan: May give faster support but doesn’t directly raise limits. ❌ C. Modify an Azure policy: Policies control resource compliance—not quota limits.

Answer 72

❌ No ✅ Explanation: Only one Account Administrator is allowed per Azure subscription. However, you can assign multiple co-administrators and role-based access control (RBAC) roles for management access.

Answer 73

Yes ❌ No ✅ Explanation: Azure subscriptions are managed through Azure Active Directory (Azure AD) accounts, which can include both work/school accounts and Microsoft accounts. However, management does not require a Microsoft account specifically. Let's clarify the roles of Azure Active Directory (Azure AD) and RBAC (Role-Based Access Control) 🔹 Azure Active Directory (Azure AD) Azure AD is the identity and access management service used by Azure. It handles: User identities (who you are) Authentication (sign-in) Directory services (group management, tenants) Account control across subscriptions 🔹 Role-Based Access Control (RBAC) RBAC controls what actions users can perform on Azure resources. It uses identities from Azure AD, and then assigns roles to determine what access those identities have. ✅ RBAC allows you to: Assign permissions like: Reader (view only) Contributor (read/write, but no delete) Owner (full access) Limit scope: Subscription level Resource group level Specific resource level (e.g., a VM or storage account) 🔄 How They Work Together: Component Function Azure AD Authenticates the user’s identity RBAC Authorizes what that user can do after authentication (actions/roles)

Answer 74

❌ No ✅ Explanation: Resource groups are part of one Azure subscription only. A subscription contains resource groups, not the other way around. A single resource group cannot span multiple subscriptions. 🔷 Azure Resource Organization Hierarchy (Top to Bottom): 1. Management Group ↓ 2. Subscription ↓ 3. Resource Group ↓ 4. Resources (VMs, Storage, Databases, etc.)

Answer 75

Correct Answer: B. No Explanation: Availability Zones are available only in selected Azure regions that have multiple physically separate datacenters. Not all Azure regions support them, so the statement is false.

Answer 76

B. No Explanation: Availability Zones support both Windows and Linux virtual machines. They are not limited to Windows Server, so the statement is incorrect.

Answer 77

B. No Explanation: Availability Zones provide high availability within a single Azure region by isolating resources across multiple zones. For cross-region replication, Azure uses services like Geo-Redundant Storage (GRS) or region pairs, not Availability Zones.

Answer 78

Correct Answer: ✅ A. Containers Explanation: Unmanaged disks in Azure are stored as page blobs in Azure Blob Storage, which are organized under containers. Containers act as folders for blob objects (like VHD files used in virtual machines). Thus, to store unmanaged VM disks, you use Containers within Azure Storage. Why other options are incorrect: ❌ B. File shares: Azure File Shares use the SMB protocol to provide shared access to files, not blobs. They’re used for mounting shared folders, not for storing virtual hard disks (VHDs). ❌ C. Tables: Azure Table Storage is a NoSQL datastore for structured, key-value-based data. It's not designed to hold files or virtual disks. ❌ D. Queues: Azure Queues are used for storing and managing messages between applications, especially for decoupling components—not for storing data files or VM disks.

Answer 79

B. A virtual network for FinServer and another virtual network for all the other servers Explanation: Azure Virtual Networks (VNets) are isolated network segments within the Azure cloud. Placing FinServer in a separate VNet ensures that it's on a distinct network segment, satisfying the compliance requirement. Option A is incorrect because resource groups are logical containers and do not isolate network traffic. Option C misunderstands VPN usage—VPNs connect on-prem to Azure, not for internal segmentation. Option D with a resource lock prevents accidental deletion/modification but doesn't impact networking. Using two separate VNets is the proper way to isolate resources at the network level in Azure.

Answer 80

Correct Answer: C. A File service in a storage account Explanation: To map a network drive from Windows 10 to Azure, you must use Azure Files, which is part of the File service in an Azure storage account. Azure File shares support SMB protocol, allowing drive letter mappings like traditional file shares. Option A (Azure SQL Database) is for relational data storage—not suitable for drive mappings. Option B (VM data disk) is attached to VMs, not accessible as a shared drive across multiple machines. Option D (Blob service) is optimized for unstructured object storage and not mountable as a drive. Therefore, Azure File service is the correct and supported solution for this use case.

Answer 81

A. Azure Cosmos DB ✅ Explanation: Azure Cosmos DB is the only database service among the 16 listed that meets both requirements: Can write data concurrently from multiple regions (multi-master replication). Natively stores JSON documents using flexible schema (NoSQL support). It is designed specifically for globally distributed, low-latency applications that handle high-volume unstructured data. ❌ Grouped Reasons Why the Other Options Are Incorrect: ❌ Relational Databases – No multi-region write: I. SQL databases J. Azure Database for PostgreSQL servers B. Azure Database for MySQL servers These are traditional relational databases. While some support JSON columns (like PostgreSQL and MySQL), they do not support multi-region write. They are not optimized for globally distributed applications. ❌ Non-distributed databases – Only regional: C. Azure Database for MariaDB servers P. SQL managed instances O. Managed databases K. SQL servers These services are single-region scoped. They don’t support multi-region data writes or NoSQL document storage. SQL Managed Instances and SQL Servers are built for enterprise scenarios but not for unstructured, distributed JSON data. ❌ Tools & Services – Not actual databases: F. Data factories H. Elastic Job agents L. Azure Database Migration Services G. Virtual Clusters These are data management tools or infrastructure components, not data storage engines. For example, Azure Data Factory is an ETL service, and Elastic Job Agents schedule queries across databases. ❌ Analytics & Cache Services – Purpose doesn’t match: D. SQL Data warehouses M. SQL Server stretch databases E. Azure Cache for Redis N. SQL elastic pools These services are meant for data warehousing, caching, or resource pooling. They don’t support multi-region writes or JSON document storage. Redis is an in-memory key-value store and unsuitable for structured query storage.

Answer 82

✅ Correct Answer: A. a subscription ✅ Explanation: A subscription is the foundational element you must create first in Azure. It represents a billing and access boundary for using Azure services. Without a subscription, you can't deploy or manage any Azure resources like virtual networks, VMs, or resource groups. B. Resource Group: Can only be created after you have a subscription. It’s used to group resources logically. C. Virtual Network: Requires a resource group and a subscription. D. Management Group: Used for organizing multiple subscriptions, so it comes after a subscription is created. Thus, creating a subscription is the first essential step in starting with Azure.

Answer 83

Correct Answer: B. No Explanation: Resources in a resource group can be in different regions. The region of the resource group itself only specifies where its metadata is stored—not a restriction on where its resources can reside. For example, a VM in East US and a database in West Europe can still exist in the same resource group.

Answer 84

B. No Explanation: Tags are not automatically inherited by resources within a resource group. You must explicitly assign tags to each individual resource if you want them to share the same tagging metadata for management and billing purposes.

Answer 85

A. Yes Explanation: Role-Based Access Control (RBAC) in Azure supports scoping permissions to a resource group level. When you assign a role at the resource group level, those permissions cascade down to all resources within the group—unless explicitly overridden at a more granular level.

Answer 86

D. must be rehydrated before the data can be accessed Explanation: Data stored in the Archive access tier is offline and cannot be read or modified directly. To access it, you must first rehydrate it to either the Hot or Cool tier, which can take several hours. This process is necessary before any reading or downloading is possible, making the Archive tier suitable for infrequently accessed, long-term storage. Options A, B, and C are incorrect because: A: Even with tools like azcopy.exe, archived data cannot be accessed until it is rehydrated. B: Azure Backup is not the only way to access or manage archive data. C: While "restoring" sounds similar, the correct Azure terminology is rehydration. Azure Backup is a service that: Automates backup of VMs, databases, file shares, etc. Uses vaults (Recovery Services Vault or Backup Vault). May use Archive tier for storing backup data (e.g., long-term retention), but it is not mandatory to use it for Archive data access.

Answer 87

Correct Answers: Minimum number of virtual machines: B. 2 Minimum number of availability zones: B. 2 Explanation: To achieve 99.99% availability, Azure requires at least two virtual machines deployed across two different Availability Zones. Each zone is a separate physical location within a region with its own power, cooling, and network. This configuration provides zone redundancy and protects your application from data center failures. Deploying to only one VM or one zone won't meet the high availability SLA.

Answer 88

Correct Answers: ✅ A. Azure Event Hubs ✅ C. Azure Monitor Explanation: Azure Event Hubs is a highly scalable data streaming platform used to ingest and store events from multiple sources. It acts as a centralized hub for collecting real-time event data from various producers (apps, devices, services), allowing downstream consumers to process the data. Azure Monitor can also collect and analyze telemetry data from multiple Azure resources, offering centralized visibility into infrastructure and application health. Other options are incorrect because: B. Azure Analysis Services is used for building analytical data models, not for event collection. D. Azure Stream Analytics is used to process data after it is ingested, not for centralized collection.

Answer 89

✅ B. within a single Azure region Explanation: Azure Availability Zones are physically separate datacenters located within a single Azure region. Each zone is made up of one or more datacenters with independent power, cooling, and networking. They are designed to ensure high availability and resiliency in case one zone fails. Other options are incorrect because: A. Across two continents and C. Within multiple Azure regions describe Geo-redundancy, not Availability Zones. D. Within a single Azure datacenter is incorrect since each zone spans separate datacenters, not a single one.

Answer 90

Correct Answer: ❌ No Explanation: ✅ Always (Default Behavior): Locally Redundant Storage (LRS) is applied by default. This creates three copies of your data within a single Azure data center in the region where the storage account is created. If ZRS (Zone-Redundant Storage) GRS (Geo-Redundant Storage) RA-GRS (Read-Access GRS) GZRS / RA-GZRS was choose when setting up the storage account. Then data will be automatically backed up to another Azure data center.

Answer 91

Correct Answer: ✅ No Explanation: Azure Storage accounts can support much more than 2 TB, but this statement is still technically correct because they can contain at least 2 TB and a million files. For example, Blob storage supports up to 5 PB per storage account, depending on the performance tier and replication type.

Answer 92

Correct Answer: ❌ No Explanation: Availability Zones are only available in select Azure regions that support zone-redundant infrastructure. Even if you have resources in every region, you cannot implement Availability Zones in regions that don't support them.

Answer 93

Correct Answer: ❌ No Explanation: Availability Zones support various virtual machine types and operating systems, including both Windows Server and Linux. They are not limited to Windows Server VMs.

Answer 94

Correct Answer: ❌ No Explanation: Availability Zones provide redundancy within a single Azure region by distributing resources across multiple datacenters. Replicating data across multiple regions is handled by Azure paired regions, not Availability Zones.

Answer 95

Correct Answer: ❌ No Explanation: North America contains multiple Azure regions, such as East US, West US, Central US, and Canada Central. A single continent can have several regions.

Answer 96

Answer 98

A: ❌ B. No Explanation: While virtual machine scale sets improve high availability and scalability, this solution does not guarantee protection from data center failure unless the scale sets are explicitly distributed across Availability Zones (i.e., different physical data centers within a region). By default: VMs in a scale set can span fault domains and update domains, but not necessarily Availability Zones. To meet the goal, you must deploy VMs across multiple Availability Zones, which are separate data centers. ✅ Correct solution: Deploy the VMs to multiple Availability Zones to ensure resiliency against a single data center failure. 📝 Example Use Case: Suppose you have a web app that needs more servers during peak traffic hours: A scale set automatically increases VM count. During off-peak times, it reduces them — saving cost and improving performance. You cannot convert a regular VM to a scale set later. You must choose the correct option at creation time.

Answer 105

✅ Yes Explanation: Availability Zones are physically separate datacenters within an Azure region. Deploying VMs across zones protects them from a datacenter-level failure.

Answer 106

❌ No Explanation: Availability Zones are within the same region, so they do not protect against region-level outages. Use Geo-redundant options (like GRS or region pairing) for regional failure protection.

Answer 107

✅ Yes Explanation: Azure managed disks can be zone-redundant, which means they are replicated across zones within a region to guard against datacenter-level failures. Key Features of Azure Managed Disks Azure Managed Disks are automatically used by default when you create a virtual machine (VM) in Azure. * Azure handles the storage account, scalability, security, and performance. You just create and attach disks. Types * Premium SSD (high-performance) * Standard SSD (cost-effective, better than HDD) * Standard HDD (lowest cost) * Ultra Disk (extremely high IOPS and throughput) Disks can be Locally Redundant (LRS), Zone-Redundant (ZRS), or Geo-Redundant (GRS) depending on availability and backup needs. Disks can be Locally Redundant (LRS), Zone-Redundant (ZRS), or Geo-Redundant (GRS) depending on availability and backup needs. Supports server-side encryption and integration with Azure Key Vault for customer-managed keys. You can take snapshots of disks and use Azure Backup for disaster recovery. Disks range from a few GB to multiple TB. Performance scales with disk size (especially for Premium and Ultra Disks).

Answer 295

✅ Correct Formula: Monthly Uptime % = (1,440 – 60) ÷ 1,440 × 100 Explanation: Maximum Available Minutes: Total possible minutes in the month (in this case, 1,440 for a single day). Downtime: Time the service was unavailable (60 minutes). The formula calculates uptime by subtracting downtime from total available minutes, dividing by total minutes, and multiplying by 100 to get the percentage. This gives: ( 1 , 440 – 60 ) ÷ 1 , 440 × 100 = ( 1 , 380 ÷ 1 , 440 ) × 100 ≈ 95.83 (1,440–60)÷1,440×100=(1,380÷1,440)×100≈95.83

Correct Answer: B. No Explanation: Building a data center is a Capital Expenditure (CapEx) because it involves a large upfront investment in physical infrastructure.

Answer 457

Correct Answer: A. Yes Explanation: OpEx includes recurring operational costs like employee salaries, utilities, and maintenance.

Answer 458

Correct Answer: A. Yes Explanation: Leasing software is a recurring cost, and thus considered operational expenditure (OpEx), as opposed to a one-time software purchase (CapEx).

Answer 459

Correct Answer: A. Platform as a Service (PaaS) Explanation: Azure Cosmos DB is a globally distributed, fully managed NoSQL database service, which means the infrastructure and runtime are abstracted. You manage only the data and access policies, not the hardware or operating system, making it a PaaS solution. IaaS is incorrect because you do not manage the OS or VM layer. Serverless refers to compute-based event-driven models. SaaS would apply to full applications like Outlook or Microsoft 365.

Answer 460

Correct Answer: B. No Explanation: With SaaS, the service provider (e.g., Microsoft) manages all aspects of the application, including updates and maintenance. Users only consume the service.

Answer 461

Correct Answer: A. Yes Explanation: IaaS provides virtualized computing resources. Users are responsible for installing and maintaining the OS and any required applications.

Answer 462

Correct Answer: A. Yes Explanation: Azure Backup is a PaaS offering because it abstracts the underlying infrastructure and provides a managed backup service that users can configure and use directly.

Answer 463

Correct Answer: B. No Explanation: Resource groups in Azure are flat, not hierarchical. You cannot nest one resource group inside another.

Answer 464

Correct Answer: B. No Explanation: Each Azure resource, including virtual machines, belongs to exactly one resource group at a time.

Answer 465

Correct Answer: A. Yes Explanation: A resource group can hold resources from different Azure regions, even though the resource group itself is created in one region.

Answer 466

Correct Answer: B. No Explanation: Running SQL Server on an Azure virtual machine is Infrastructure as a Service (IaaS), not PaaS. You are responsible for managing the OS and software.

Answer 467

Correct Answer: A. Yes Explanation: Azure SQL Database is a fully managed PaaS offering that handles backups, patching, high availability, and scalability for you.

Answer 468

Correct Answer: B. No Explanation: Azure Cosmos DB is a PaaS (Platform as a Service) offering. It’s a globally distributed, multi-model database service managed by Microsoft.

Answer 469

Correct Answer: C. Platform as a service (PaaS) Explanation: When Azure manages the underlying infrastructure, OS, and software updates of a cloud-hosted SQL Server database, it qualifies as PaaS. IaaS would require you to manage the updates yourself. SaaS would refer to ready-to-use applications, not databases you manage. DRaaS is unrelated to the standard hosting and maintenance of databases.

Answer 470

Correct Answer: C. An Azure App Service and Azure SQL databases Explanation: Azure App Service is a PaaS offering for hosting web apps. Azure SQL Database is a PaaS relational database service. This combination ensures the environment uses only PaaS, fulfilling the company’s migration plan. Incorrect options: A, B, D all involve virtual machines, which are IaaS, not PaaS.

Answer 471

Correct Answer: A. Application data Explanation: In the SaaS model, the cloud provider manages everything: infrastructure, platform, and software. The customer only provides and manages the application data (like user records, inputs, preferences, etc.). Incorrect options: B. Data storage, C. Compute resources, and D. Application software are all managed by the provider in SaaS.

Answer 472

✅ Correct Answer: Yes Explanation: Azure Files provides managed file shares in the cloud using standard SMB protocol. It's categorized under IaaS because you are responsible for managing the data and structure of the storage, but not the underlying infrastructure.

Answer 473

❌ Correct Answer: No Explanation: A DNS server on an Azure VM is IaaS, not PaaS. Since the DNS service is running on a VM you manage, you handle the OS and server configuration, which is characteristic of IaaS, not PaaS.

Answer 474

✅ Correct Answer: Yes Explanation: Microsoft Intune is SaaS because it is a fully managed cloud service provided by Microsoft for device management. You don’t need to manage servers or infrastructure—it’s accessible over the internet as a complete software solution.

Answer 475

✅ Correct Answer: D. Define Strategy Explanation: This step focuses on understanding business motivations, defining outcomes, and prioritizing projects before any planning or deployment. 1. Define Strategy 2. Plan 3. Ready 4. Adopt 5. Govern 6. Manage

Answer 476

✅ Answer: Yes Explanation: Cloud computing services are delivered over the internet. You need internet connectivity to access cloud resources such as servers, storage, applications, and analytics tools hosted on the cloud. Without an internet connection, these services cannot be utilized.

Answer 477

✅ Answer: disaster recovery Explanation: Azure Site Recovery replicates workloads running on physical and virtual machines from a primary site to a secondary location. In the event of a site outage, you can fail over to the secondary location and continue to access your apps and data. This makes disaster recovery the correct answer.

Answer 478

✅ App1: Platform as a Service (PaaS) ✅ App2: Infrastructure as a Service (IaaS) Explanation: App1: PaaS allows you to write and modify code without managing the underlying OS. This reduces admin effort while allowing development flexibility. App2: IaaS provides full control over the operating system, which is required when the app needs to interact directly with the server environment.

Answer 479

✅ Correct Answer: B. Infrastructure as a Service (IaaS) Explanation: App1 is a legacy application, and moving it to the cloud without major code changes is a classic "Lift & Shift" scenario. IaaS lets you replicate your current on-premises environment (servers, OS, and network) in the cloud using virtual machines. This approach avoids refactoring the application. Why not A (PaaS)? PaaS requires rewriting or adjusting the application to fit into a managed platform (e.g., Azure App Services), which legacy apps often can't support without significant changes. Why not C (SaaS)? SaaS provides ready-made software (like Microsoft 365) that you can use directly — you can’t move your custom/legacy app into SaaS.

Answer 480

✅ Correct Answer: Platform as a Service (PaaS) Explanation: PaaS provides a managed environment for application development and hosting. When using Azure SQL Database, Microsoft handles the infrastructure, patching, backups, and software updates, while you manage the database and data. This level of abstraction is characteristic of Platform as a Service (PaaS). Why not the others? ❌ DRaaS is specific to disaster recovery solutions. ❌ IaaS would require you to manage the OS, database software, and updates yourself. ❌ SaaS refers to fully managed end-user applications, not development platforms like databases.

Answer 481

❌ Correct Answer: No Explanation: Virtual networks (VNets) in the same Azure region are not connected by default. To allow communication, you must configure virtual network peering. Peering enables resources in different VNets to communicate as if they were on the same network.

Answer 482

✅ Correct Answer: Yes Explanation: Resource names must be unique within their scope. For VNets, the scope is the resource group, so each virtual network in a resource group must have a unique name.

Answer 483

✅ Correct Answer: Yes Explanation: To ensure proper routing and avoid IP conflicts, each VNet’s address space (CIDR block) must be non-overlapping and unique within the same subscription and network topology.

Answer 484

✅ Correct Answer: B. Vertical scaling Explanation: Vertical scaling (also called scale up/scale down) refers to increasing a single VM’s capacity by adding more CPU, RAM, or storage. This is different from: ❌ A. Agility – Refers to the speed and flexibility of responding to changes. ❌ C. Horizontal scaling – Adds more VMs (instances) rather than upgrading one. ❌ D. Elasticity – Refers to the ability to automatically scale resources up or down based on demand, which could involve either vertical or horizontal scaling.

Answer 485

✅ Correct Answer: D. Isolation and segmentation Explanation: Azure Virtual Networks (VNets) enable isolation and segmentation of resources by allowing you to define subnets, network security groups, and route tables. This segmentation is key to controlling access and enforcing governance. Why not the others? ❌ A. Resource cost analysis – Done via Azure Cost Management, not a VNet feature. ❌ B. Packet inspection – Requires Azure Firewall or third-party tools, not a core VNet feature. ❌ C. Geo-redundancy – Applies to services like Azure Storage or SQL, not VNets.

Answer 486

✅ Correct Answer: D. Scalability Explanation: Scalability refers to the ability to dynamically increase (or decrease) resources such as compute, memory, or storage to meet workload demands.

Answer 487

✅ Correct Answer: D. An Azure data center failure Explanation: Availability Zones are physically separate locations within an Azure region, each with independent power, cooling, and networking. They are designed to protect your apps and data against the failure of an entire Azure datacenter within a region. If one zone goes down, the others continue operating. Why not the others? ❌ A. Physical server failure – Typically handled by Azure’s VM infrastructure or availability sets. ❌ B. Azure region failure – Requires geo-replication across regions, not availability zones. ❌ C. Storage failure – Azure has built-in redundancy at the storage level (e.g., LRS, ZRS, GRS).

Answer 488

❌ Correct Answer: B. No Explanation: Virtual Machine Scale Sets provide high availability and automatic scaling within a region, but this answer does not specify that the scale set is deployed across multiple Availability Zones. To ensure resilience against a single data center failure, you must explicitly configure zone redundancy. Without zone distribution, VMs might all reside in a single data center, so a failure would still cause downtime.

Answer 489

❌ Correct Answer: No Explanation: An Azure subscription can be associated with only one Azure AD tenant at a time. However, an Azure AD tenant can be linked to multiple subscriptions.

Answer 490

✅ Correct Answer: Yes Explanation: You can change the Azure AD tenant associated with a subscription. However, this requires careful planning since role assignments and permissions may be affected during the transition.

Answer 491

❌ Correct Answer: No Explanation: When a subscription expires, you lose access to its resources, but the Azure AD tenant remains active. It is not deleted and can still be used or reassigned to another subscription.

Answer 492

✅ Correct Answer: B. Management groups Explanation: Management groups are designed to manage access, compliance, and policies across multiple Azure subscriptions. They provide a hierarchical scope above subscriptions. Why not the others? ❌ A. Resource groups – These group resources within a subscription, not across multiple ones. ❌ C. Azure policies – Enforce compliance at or below the subscription level, not manage subscriptions themselves. ❌ D. Azure App Service plans – These are for hosting web apps, unrelated to compliance or multi-subscription management.

Answer 493

✅ Correct Answers: A. Multiple subscriptions and D. Multiple resource groups Explanation: ✅ A. Multiple subscriptions allow billing separation and management boundaries. Each department can have its own subscription and administrator. ✅ D. Multiple resource groups help organize and manage resources within a subscription by grouping related items. Admin rights can be scoped to resource groups. Why not the others? ❌ B. Multiple Azure AD directories would complicate identity management and are not required for department-level resource segregation. ❌ C. Multiple regions relate to geographic deployment, not administrative segmentation.

Answer 494

✅ Correct Answer: Yes Explanation: A single Azure account (user identity) can manage multiple subscriptions. This is common for organizations that separate dev/test/prod or departments into different subscriptions.

Answer 495

❌ Correct Answer: No Explanation: Azure does not support merging two subscriptions. However, you can move some resources between subscriptions and transfer ownership, but the subscriptions remain distinct.

Answer 496

✅ Correct Answer: Yes Explanation: A company can create and manage multiple subscriptions, each containing its own set of resources. This allows for organizational and billing separation. Note: A single resource can only belong to one subscription at a time.

Answer 497

✅ Correct Answer: The virtual machines can be moved to the new subscription. Explanation: Azure supports moving virtual machines between subscriptions, provided both subscriptions exist under the same Azure AD tenant. You can move VMs using the Azure portal, PowerShell, or Azure CLI. The VM does not need to be stopped, and most resources will continue to run during the move. You do not need to match OS versions or keep VMs in the same resource group to move them.

Answer 498

✅ Correct Answers: A. A virtual network gateway and E. A gateway subnet Explanation: To connect on-premises clients to Azure VMs, you typically set up a VPN connection: ✅ A. Virtual network gateway: Acts as the VPN endpoint in Azure. ✅ E. Gateway subnet: A required subnet inside the virtual network to host the virtual network gateway. Why not the others? ❌ B. Load balancer: Distributes traffic among VMs; not needed for VPN. ❌ C. Application gateway: For HTTP load balancing and web traffic. ❌ D. Virtual network: Required, but assumed to already exist since VMs are deployed.

Answer 499

✅ Correct Answer: D. Create a new support request Explanation: Many Azure services have quota (limit) restrictions by default. To request an increase: You must create a support request through the Azure portal. Choose the “Service and subscription limits (quotas)” issue type. Then specify the service (e.g., SQL Database Managed Instance) and the required increase. Why not the others? ❌ A. Service health alert: Not related to quotas or limits. ❌ B. Upgrade support plan: Doesn’t affect service quotas. ❌ C. Azure policy: Enforces rules, doesn’t increase limits.

Answer 500

❌ Correct Answer: No Explanation: Each Azure subscription can only have one account administrator. However, you can assign multiple service administrators and co-administrators or use Role-Based Access Control (RBAC) for more granular permissions.

Answer 501

❌ Correct Answer: No Explanation: Azure subscriptions are typically managed using Azure Active Directory (Azure AD) accounts. A Microsoft Account (MSA) (like Outlook.com) can be used initially, but enterprise subscriptions rely on Azure AD identities for proper access control and management.

Answer 502

❌ Correct Answer: No Explanation: A resource group belongs to a single Azure subscription. Subscriptions contain resource groups — not the other way around.

Answer 503

❌ Correct Answer: No Explanation: Not all Azure regions support Availability Zones. Only selected regions offer zone support to ensure physical separation of infrastructure for high availability.

Answer 504

❌ Correct Answer: No Explanation: Availability Zones support many types of virtual machines, including Linux-based VMs, and other services like managed disks, load balancers, and more — not just Windows Server.

Answer 505

❌ Correct Answer: No Explanation: Availability Zones provide redundancy within a single Azure region, not across multiple regions. To replicate across multiple regions, you use geo-redundant services like Azure GRS storage or Azure Site Recovery.

Answer 506

✅ Correct Answer: Containers Explanation: Unmanaged disks in Azure are stored as page blobs, which are a type of blob stored inside Azure Storage containers. This means containers (part of Blob Storage) are used to store both OS and data disks when using unmanaged storage. Why not the others? ❌ File shares: Used for SMB-based file sharing. ❌ Tables: Used for structured NoSQL data. ❌ Queues: Used for messaging between components in distributed apps.

Answer 507

✅ Correct Answer: B. A virtual network for FinServer and another virtual network for all the other servers Explanation: To meet the requirement of placing FinServer on a separate network segment, it must be placed in a different virtual network than the other servers. Azure automatically routes traffic within a virtual network across subnets, so using different subnets alone is not sufficient for isolation. Why not the others? ❌ A. Resource groups are used for resource management, not network segmentation. ❌ C. VPN and virtual network gateway are for connecting on-premises networks to Azure, not isolating servers. ❌ D. Resource locks prevent accidental deletion/modification, not network isolation.

Answer 508

✅ Correct Answer: C. A File service in a storage account Explanation: To map a network drive from Windows 10 to Azure, you use Azure Files, which is a File service under Azure Storage. Azure Files supports SMB (Server Message Block) protocol, which allows you to mount file shares just like traditional network drives. Why not the others? ❌ A. Azure SQL Database – It's for relational data, not file sharing. ❌ B. Virtual machine data disk – Attached only to a VM, not shareable across machines. ❌ D. Blob service – Good for unstructured data, but doesn't support mounting as a network drive.

Answer 509

✅ Correct Answer: No Explanation: Tags are not automatically inherited by resources from the resource group. You must assign tags individually to each resource if needed. ❌ Why not Yes: Tag inheritance doesn’t occur by default in Azure. This behavior must be configured manually or via automation.

Answer 510

✅ Correct Answer: Yes Explanation: Role-Based Access Control (RBAC) allows permissions set at the resource group level to be inherited by all the resources within that group by default. ❌ Why not No: Unless explicitly overridden, resource-level permissions inherit from the group level, allowing management access.

Answer 511

✅ Correct Answer: D — must be rehydrated before the data can be accessed Explanation: Data stored in the Archive access tier is offline and cannot be read or modified directly. To access it, you must rehydrate the blob to an online tier (such as Hot or Cool). This process can take several hours depending on the size and priority of the rehydration. ❌ Why not the others: A is incorrect: Data cannot be accessed directly with azcopy.exe while in the archive tier. B is incorrect: Azure Backup is not the only tool, and not required specifically for archive access. C is a vague version of the correct answer — “rehydration” is the precise term Azure uses, not just "restore."

Answer 512

✅ Correct Answer: No Explanation: Not all Azure regions support Availability Zones. Only selected regions offer this feature, and it must be supported natively by the region’s infrastructure.

Answer 513

✅ Correct Answer: No Explanation: Availability Zones support both Windows and Linux virtual machines. The feature is not limited to any specific operating system.

Answer 514

✅ Correct Answer: No Explanation: Availability Zones are used to replicate data and applications across physically separate datacenters within a region to ensure high availability and fault tolerance. They help protect against data center-level failures.

Answer 515

✅ Correct Answer: No Explanation: North America includes multiple Azure regions such as East US, West US, Central US, South Central US, and Canada East/West. It is not limited to a single region.

Answer 516

✅ Correct Answer: Yes Explanation: An Azure region is composed of one or more datacenters connected through a low-latency network, ensuring high availability and redundancy within the region.

Answer 517

✅ Correct Answer: No Explanation: Data transfer across regions incurs outbound transfer charges. Only inbound data is free in Azure; outbound traffic (especially cross-region) is billed according to standard pricing.

Answer 518

✅ Correct Answer: B — No Explanation: While scale sets help manage and auto-scale groups of VMs for load balancing and high availability, the solution does not state that the scale sets span multiple availability zones or data centers. To ensure resilience against a single data center failure, VMs should be distributed across multiple availability zones, not just across multiple scale sets. Without this, a single data center outage could still affect all VMs in a scale set.

Answer 519

✅ Correct Answer: B — Azure Service Health Explanation: Azure Service Health provides a personalized dashboard for tracking the health of Azure services and regions relevant to your subscriptions. It notifies you about: Planned maintenance Service incidents Health advisories It is the recommended tool for receiving alerts about events that could impact your Azure resources. ❌ Why not the others: A. Azure Monitor tracks performance and diagnostics, not service-wide maintenance events. C. Azure Advisor offers best practice recommendations, not service health alerts. D. Microsoft Trust Center provides compliance and security info, not real-time notifications.

Answer 527

✅ Correct Answer: B — No Explanation: A resource group belongs to only one subscription. While a subscription can have multiple resource groups, a resource group cannot span across subscriptions.

Answer 528

✅ Correct Answer: A — Yes Explanation: For a user to sign in to a Windows 10 device using Azure AD credentials, the device must be either Azure AD joined or Hybrid Azure AD joined. Otherwise, sign-in with Azure AD credentials won't work.

Answer 529

✅ Correct Answer: B — No Explanation: Resource groups are used to organize Azure resources, not users. Users in Azure AD are organized through groups and roles, not resource groups.

Answer 530

✅ Correct Answer: A — Yes Explanation: Azure AD supports dynamic groups, which use rules to automatically add or remove members based on user or device attributes (like department, location, or job title).

Answer 531

✅ Correct Answers: A and D Explanation: A. Availability Zones are physically separate datacenters within a region, designed to protect against data center-level failures. Deploying VMs across zones ensures continued availability even if one zone goes down. D. Regions are geographically separate. Deploying across regions adds protection from regional failures, not just datacenter ones. This is more resilient but may increase complexity and latency. ❌ Why not B: Resource groups are a logical container for organizing resources, but they do not provide redundancy or failure isolation. ❌ Why not C: Scale sets provide high availability and auto-scaling within a region, but unless explicitly configured with availability zones, they do not guarantee resilience against a data center failure.

Answer 532

✅ Correct Answer: A — Be deployed to a separate virtual network Explanation: In Azure, virtual machines within the same virtual network (VNet) can communicate with each other by default, even if they are in different subnets. To prevent VM1 from connecting to the other VMs, it must be placed in a separate virtual network, as communication across VNets is blocked unless explicitly enabled (via peering, gateways, etc.). ❌ Other options: B. Different OS: Doesn’t affect network connectivity. C. Different resource group: Resource groups are just for management and organization. D. Two NICs: Might add connectivity options, not restrict them.

Azure Virtual Desktop: Used for delivering remote desktops, not for container management. B. Azure Virtual Machines: Can run containers manually, but lacks built-in container orchestration. C. Azure Functions: Can run containerized code but isn't used to manage containers — it's a serverless compute option.

Answer 549

✅ Correct Answer: C — To the same resource group Explanation: Resource groups allow you to apply Role-Based Access Control (RBAC) at the group level. When virtual machines are in the same resource group, you can assign permissions once at the group level, and those permissions apply to all contained resources, including VMs. ❌ Other options: Region and availability zone affect location and redundancy, not permissions ARM templates are for deployment, not access control

Answer 550

✅ Correct Answer: A — No change is needed Explanation: Azure SQL Data Warehouse (now Azure Synapse Analytics) is a Platform as a Service (PaaS) offering, and high availability is inherently built into the platform. Microsoft guarantees an SLA of 99.9% uptime due to this feature. ❌ Incorrect options: B. Automatic scaling is available but not the primary benefit discussed. C. Data compression improves storage efficiency, not availability. D. Versioning refers to tracking changes over time, which is unrelated to availability. High Availability: ⚠️ Yes, but depends on the redundancy option chosen. Data Lake Storage is built on Azure Blob Storage, and high availability is not automatic — it depends on the redundancy configuration: Locally-redundant storage (LRS): Data is replicated within a single data center. Geo-redundant storage (GRS): Data is replicated across regions for disaster recovery. Zone-redundant storage (ZRS): Data is spread across availability zones. So, while both support high availability, Azure Synapse has it built-in by design, whereas Azure Data Lake requires explicit configuration via redundancy options.

Answer 551

✅ Correct Answer: A — Yes Explanation: Deploying virtual machines to two or more Azure regions ensures that the services remain available even if an entire data center or region fails, because: Each Azure region consists of multiple data centers. Cross-region deployment offers geo-redundancy, making your solution resilient to regional outages. This approach fully meets the goal of ensuring service availability during a single data center failure.

Answer 552
