Question

Difficulty: MediumAzure Virtual Machine Backup Configuration

An administrator is configuring a backup solution for an Azure virtual machine named vm-hr-prod. The virtual machine has the following configuration:
- OS: Windows Server 2022
- Region: East US 2
- Disks: Two Premium SSD managed disks

The administrator must ensure that the backup data is replicated to a secondary region for disaster recovery and that all backup operations succeed without network access issues to staging resources.

Which of the following configurations should the administrator implement?

  1. A
    Create a Recovery Services vault in the West US 2 region, set the vault storage replication type to Locally-redundant storage (LRS), and enable backup for the virtual machine.
  2. B
    Create a Recovery Services vault in the East US 2 region, configure the backup policy to use a staging storage account, and disable the 'Allow trusted Microsoft services to access this storage account' setting on the staging storage account's firewall.
  3. Create a Recovery Services vault in the East US 2 region, configure the vault's storage replication to Geo-redundant storage (GRS), and enable backup for the virtual machine.Answer
  4. D
    Create a Recovery Services vault in the East US 2 region, and configure the backup policy with 'Replace existing' as the default recovery operation for scheduled backups.

Answer

Create a Recovery Services vault in the East US 2 region, configure the vault's storage replication to Geo-redundant storage (GRS), and enable backup for the virtual machine.
To back up an Azure virtual machine, the Recovery Services vault must reside in the same Azure region as the virtual machine (East US 2). To replicate backups to a secondary region (West US 2, which is the paired region for East US 2), the storage replication type of the Recovery Services vault must be configured as Geo-redundant storage (GRS).

Step-by-Step Solution

1
Determine the correct region for the Recovery Services vault.
The Recovery Services vault must be deployed in the same region as the virtual machine (East US 2).
Azure Backup does not support backing up virtual machines to a Recovery Services vault located in a different region.
2
Configure the storage replication settings for the Recovery Services vault.
Set the vault storage replication type to Geo-redundant storage (GRS) before configuring backups.
GRS ensures that backup data is replicated to the secondary paired region (West US 2) for disaster recovery.
3
Enable backup for the virtual machine within the vault.
The virtual machine is associated with a backup policy inside the vault, initiating the backup process.
This establishes the relationship and starts the protection schedule.
