Describe core Azure services Flashcards
A company is currently planning to deploy resources to Azure. They want to have the ability to manage user access to resources across multiple subscriptions. Which of the following can help you achieve this requirement?
Resource groups
Management groups
Azure Policies
Azure App service
Management Groups, these are containers for managing access across multiple Azure subscriptions.
A company wants to deploy a set of Azure Windows VMs. They want to ensure that the VMs services are still accessible even if a single data center goes down.
They decide to deploy the set of VMs to two or more availability zones.
Would this fulfill the requirement?
Yes/No
Yes, availability zones can be used in the case of a data center-wide failure.
There can be multiple availability zones within an Azure region. These zones seperate fault and update domains.
If you were to create 3 VMs across 3 zones in an Azure region your VMs would all update at different times to maintain availability.
With availability zones Azure offers 99.99% VM uptime SLA.
Can region pairs be used to replicate data asynchronously across multiple regions for diaster recovery protection?
Yes/No
No, Availability zones are only specific to a region.
A regional pair consists of two regions within the same geography.
Azure serialises platofmr updates across region pairs to ensure that one region in each pair updatas at a time.
If an outage affects multiple regions, at least one region in evach pair will be prioritised for recovery.
Your company plans to use the Azure App Service (PaaS) to host its set of web applications. In case of need as per requirement, does Azure help in providing the ability to scale the platform automatically in hosting the web applications?
Yes/No
Yes
Azure Web Apps have many ways to scale their infrastrucute based on the demand and load on the web app itself.
Scale up: Get more CPU, memory, disk space etc. You scale up by chaning the pricing tier of the App Service plan that your app belongs to.
Scale out: Increase the number of VM instances that run your app.
A company has set up a VPN device on their on-premises that will be used for site-to-site connection from an on-premises location to Azure. Which of the following would represent the on-premises VPN device in Azure?
DNS zone
Application gateway
Local network gateway
Virtual network gateway
Local network gateway
The local network gateway typically refers to you on-premises location. You give the site a name by which Azure can refer to it, then specify the IP address of the on-premises VPN device to which you will create a connection. You also specify the IP address prefixes that will be routed through the VPN gateway to the VPN device. The address prefixes you specify are the prefixes located on your on-premises network. If your on-premises network changes or you need to change the public IP address for the VPN device, you can easily update the values later.
A company is planning to deploy resources to Azure. Which of the following in Azure provides a platform for defining the dependencies between resources so they’re deployed in the correct order?
Azure resource groups
Azure policies
Azure management groups
Azure resource manager
Azure resource manager
It allows you to:
Manage your infrastrcuture through declarative templates rather than scripts.
Deploy, manage and monitor all the resources for your solution as a group, rather than handling them individually.
Redeploy your solution throughout the development lifecycle and have confidence your resources are deployed in a consistent state.
Define the dependencies between resources so they’re deployed in the correct order.
Apply access control to all services in your resource group because Role-Based Access Control (RBAC) is natively integrated into the management platform.
Apply tags to resources to logically organise all the resources in your subscription.
Clarify your organisations billing by viewing costs for a group of resources sharing the same tag.
A company is planning to set up a solutioni on the Azure platform. The solution has the following main key requirement.
Provide a managed service that could be used to manage and scale container-based applications.
Which of the following would be best suited for this requirement?
Azure Event Grid
Azure DevOps
Azure Kubernetes
Azure DevTest Labs
Azure Kubernetes
The fully managed Azure Kubernetes Service (AKS) makes deploying and managing containerised applications easy. It offers serverless Kubernetes, an integrated continuous integration and continuous delivery (CI/CD) experience, and enterprise-grade security and governance. Unite your development and operations teams on a single platform to rapidly build, deliver, and scale applications with confidence.
A company is planning to set up a solution in Azure. The solution would have the following key requirement.
Provide an efficient way to distribute web content to uers across the world.
Which of the following would be best suited for this requirement?
Azure content delivery network
Azure SQL datawarehouse
Azure load balancer
Azure HD insight
Azure Content Delivery Network
A content delivery network (CDN) is a distributed network of servers that can efficiently deliver web content to users. CDNs store cached content on edge servers in point-of-presence (POP) locations that are close to end users to minimise latency.
A company has just set up an Azure subscription and an Azure tenant. They want to start deploying resources on the Azure platform. They want to implement a way to group the resources logically. Which of the following could be used for this requirement?
Availability zones
Azure resource groups
Azure resource manager
Azure regions
Azure resource groups
A resource group is a container that holds related resources for an Azure solution. The resource group can include all the resources for the solution, or only those resources that you want to manage as a group. You decide how you want to allocate resources to resource groups based on what makes the most sense for your organization. Generally, add resources that share the same lifecycle to the same resource group so you can easily deploy, update, and delete them as a group.
A team has an object named audio.log stored in the Blob service in the Azure storage account. A partial snapshot of the properties gives the details below.
Type: Block blob
Access Tier: Archive
Which of the following needs to be done bbefore the object can be accessed?
Create a snapshot of the object
Rehydrate the object
Change the type of the object
Change the URL of the object
Rehydrate the object
While a blob is in the Archive access tier, it’s considered to be offline and can’t be read or modified. In order to read or modify data in an archived blob, you must first rehydrate the blob to an online tier, either the Hot or Cool tier.
