Question

Difficulty: Very hardAzure Virtual Machine Backup Configuration

You have an Azure virtual machine named VM1 that runs Windows Server 2022 and is deployed in the West US 2 region. VM1 contains the following disks:
* An OS disk that is a Premium SSD
* A data disk named Disk1 that is a Premium SSD
* A data disk named Disk2 that is an Ultra Disk

You need to configure backup for VM1 by using Azure Backup. The solution must meet the following requirements:
* Back up the OS disk and Disk1.
* Minimize administrative effort.
* Support restoring VM1 to a secondary region in the event of a regional outage in West US 2.

Which configuration should you implement?

  1. Create a Recovery Services Vault in the West US 2 region, configure the vault storage replication to Geo-Redundant Storage (GRS) with Cross-Region Restore enabled, and configure a backup policy that excludes Disk2.Answer
  2. B
    Create a Recovery Services Vault in the East US 2 region, configure the vault storage replication to Locally-Redundant Storage (LRS), and configure a backup policy that includes Disk2.
  3. C
    Create a Recovery Services Vault in the West US 2 region, configure the vault storage replication to Geo-Redundant Storage (GRS) with Cross-Region Restore enabled, configure a backup policy that includes all disks, and configure the storage firewall on the vault's staging storage account to deny trusted Microsoft services.
  4. D
    Create a Recovery Services Vault in the West US 2 region, configure the vault storage replication to Zone-Redundant Storage (ZRS), and configure a backup policy that includes Disk2 while planning to use the 'Replace existing' restore option to bypass Disk2 during recovery.

Answer

Create a Recovery Services Vault in the West US 2 region, configure the vault storage replication to Geo-Redundant Storage (GRS) with Cross-Region Restore enabled, and configure a backup policy that excludes Disk2.
The correct configuration requires the Recovery Services Vault to be deployed in the same region as the virtual machine (West US 2). To support disaster recovery to a secondary region, the vault storage replication must be configured as Geo-Redundant Storage (GRS) with Cross-Region Restore enabled. Because Ultra Disks are not supported by Azure Backup, the backup policy must explicitly exclude Disk2 so that the backup configuration can be successfully established for the remaining disks (the OS disk and Disk1).

Step-by-Step Solution

1
Select the correct region for the Recovery Services Vault.
The Recovery Services Vault is created in the West US 2 region, matching the region of the source virtual machine VM1.
Azure Backup requires the Recovery Services Vault and the virtual machine being backed up to reside in the same geographical region.
2
Configure vault storage redundancy and Cross-Region Restore.
Vault storage replication is set to Geo-Redundant Storage (GRS) and Cross-Region Restore (CRR) is enabled.
GRS replicates backup data to a secondary paired region, and CRR enables restoring the virtual machine in that secondary region even if the primary region is fully functional or experiencing an outage.
3
Exclude the unsupported Ultra Disk (Disk2) in the backup policy.
The backup policy is configured with Disk2 added to the excluded disks list.
Azure Backup does not support backing up Ultra Disks. The backup configuration will fail unless unsupported disks are explicitly excluded from the backup policy.

Key Concept

Azure VM Backup requires same-region vaults, GRS with CRR for secondary region restore, and explicit exclusion of unsupported disk types like Ultra Disks.
