Difficulty: HardAzure Virtual Machine Backup Configuration

An administrator is configuring the backup and replication strategy for an Azure virtual machine named `vm-db-prod01` that runs Red Hat Enterprise Linux 8.6 in the East US region. The virtual machine has three disks: a 128 GiB Standard SSD OS disk, a 1 TiB Premium SSD data disk, and a 512 GiB Ultra Disk data disk.

The administrator must ensure that all disks are backed up and that the backups are replicated to a secondary region to support disaster recovery.

Which configuration should the administrator implement?

  1. Configure a Recovery Services Vault in the East US region with Geo-redundant storage (GRS) and Cross-Region Restore enabled, and associate the virtual machine with an Enhanced backup policy.Answer
  2. B
    Configure a Recovery Services Vault in the West US region with Geo-redundant storage (GRS) and Cross-Region Restore enabled, and associate the virtual machine with an Enhanced backup policy.
  3. C
    Configure a Recovery Services Vault in the East US region with Geo-redundant storage (GRS) and Cross-Region Restore enabled, associate the virtual machine with an Enhanced backup policy, and disable the 'Allow trusted Microsoft services to access this storage account' bypass option on the storage account containing the virtual machine's disks.
  4. D
    Configure a Recovery Services Vault in the East US region with Geo-redundant storage (GRS), associate the virtual machine with a Standard backup policy, and select 'Replace existing' as the default restore type within the policy settings.

Answer

Configure a Recovery Services Vault in the East US region with Geo-redundant storage (GRS) and Cross-Region Restore enabled, and associate the virtual machine with an Enhanced backup policy.
The correct configuration involves deploying the Recovery Services Vault in the same region as the virtual machine (East US), enabling Geo-redundant storage (GRS) along with Cross-Region Restore (CRR) to support secondary region disaster recovery, and selecting the Enhanced backup policy tier because the virtual machine contains an Ultra Disk, which is unsupported under the Standard policy tier.

Step-by-Step Solution

1
Determine the required region for the Recovery Services Vault.
The vault must be deployed in the East US region, matching the region of the virtual machine.
Azure Backup requires that the Recovery Services Vault resides in the same region as the virtual machines being backed up.
2
Determine the backup policy type needed to support the virtual machine's disk configurations.
Choose the Enhanced backup policy type.
The virtual machine contains an Ultra Disk. While Standard backup policies support Standard HDD, Standard SSD, and Premium SSD, they do not support Ultra Disks. The Enhanced backup policy is required to protect VMs with Ultra Disks.
3
Determine the storage replication and restore settings for the vault to support disaster recovery to a secondary region.
Configure the vault storage to use Geo-redundant storage (GRS) and enable Cross-Region Restore (CRR).
GRS replicates the backup data to a paired region, and CRR allows the administrator to perform restores in the secondary region even if the primary region is fully available.

Key Concept

Azure Virtual Machine backup configuration requires region alignment, correct storage redundancy (GRS/CRR) for cross-region disaster recovery, and policy tier selection (Enhanced vs Standard) based on disk types such as Ultra Disks.
