What is LRS?
Locally redundant storage (LRS)
What is GRS?
Geo-redundant storage (GRS)
What is RA-GRS
Read-access geo-redundant storage (RA-GRS)
What is ZRS
Zone-redundant storage (ZRS)
What is GZRS?
Geo-zone-redundant storage (GZRS)
What is RA-GZRS?
Read-access geo-zone-redundant storage (RA-GZRS)
Name all storage types and usage
Type Supported services Redundancy Options Usage
Standard general-purpose v2 Blob Storage (including Data Lake Storage), Queue Storage, Table Storage, and Azure Files LRS, GRS, RA-GRS, ZRS, GZRS, RA-GZRS Standard storage account type for blobs, file shares, queues, and tables. Recommended for most scenarios using Azure Storage. If you want support for network file system (NFS) in Azure Files, use the premium file shares account type.
Premium block blobs Blob Storage (including Data Lake Storage) LRS, ZRS Premium storage account type for block blobs and append blobs. Recommended for scenarios with high transaction rates or that use smaller objects or require consistently low storage latency.
Premium file shares Azure Files LRS, ZRS Premium storage account type for file shares only. Recommended for enterprise or high-performance scale applications. Use this account type if you want a storage account that supports both Server Message Block (SMB) and NFS file shares.
Premium page blobs Page blobs only LRS Premium storage account type for page blobs only.
What is SPRAGM?
Strategy - Plan - Ready - Adopt - Govern - Manage
What should the Keywords Zone make you think
Regions > Zones > Data Centre
Provide some information about Storage
LRS: Locally redundant; within ONE data center in an Availability Zone. 11 9
ZRS: Spans the 3 AvailabilityZone(AZ) within a Region (that’s why it’s called “Zone Redundant” 12 9
GRS: Exists in ONE AZ (data center) of a REGION, and another AZ (data center) of a secondary REGION 16 9 (“Geo-location” Redundant).
GZRS: Spans the 3 AZ within a Region, and asynchronously replicated to another AZ in a secondary Region. 16 9

Number of copies of data maintained on separate nodes Three copies within a single region Three copies across separate availability zones within a single region Six copies total, including three in the primary region and three in the secondary region Six copies total, including three across separate availability zones in the primary region and three locally redundant copies in the secondary region
What is the service level agreement for two or more Azure Virtual Machines that have been placed into the same Availability Set in the same region?
99.95 %
Which database product offers “sub 5 millisecond” response times as a feature?
Cosmos DB
If you wanted to get an alert every time a new virtual machine is created, where could you create that?
Azure Monitor
Fill in the blank: __________ is a mechanism that allows you to connect two virtual networks within Azure.
Peering
What is the minimum number of Availability Zones required to create a highly available application in Azure?
2
What is the primary advantage of using Azure’s built-in security features compared to managing security on-premises?
Reduced expertise required
What is the primary benefit of using PaaS compared to IaaS?
Reduced development time
(The primary benefit of using PaaS compared to IaaS is the reduced development time. PaaS platforms provide pre-built services and tools that streamline the development process, allowing developers to focus on building and deploying applications quickly without the need to manage the underlying infrastructure.)
Which of the following is NOT a characteristic of Infrastructure as a Service (IaaS)?
Managed operating system
Queue storage can be used when two programs need to communicate. Which type of communication is this best suited for?
Asynchronous communicatio
What is the maximum number of web apps a single App Service Plan (Premium v3) can support?
Unlimited
How can tags be used to optimize costs in Azure?
By categorizing resources based on their cost and usage
Which of the following is a built-in role in Azure RBAC?
Owner
What does redundancy mean in the context of Azure?
Having multiple copies of a resource to ensure availability.
