Question

Difficulty: EasyRecovery Services Vaults and Backup Vaults

An organization deploys two virtual machines across different resource groups:

* `VM-App-East` in resource group `RG-East`, located in the East US region.
* `VM-Web-West` in resource group `RG-West`, located in the West US region.

The environment also contains two Recovery Services vaults:

* `RSV-East` in resource group `RG-Backups`, located in the East US region.
* `RSV-West` in resource group `RG-Backups`, located in the West US region.

You need to configure backups for both virtual machines. Which two configurations should you use? (Select two.)

  1. Back up `VM-App-East` to `RSV-East`Answer
  2. Back up `VM-Web-West` to `RSV-West`Answer
  3. C
    Back up `VM-App-East` to `RSV-West`
  4. D
    Back up `VM-Web-West` to `RSV-East`

Answer

Configure backup for the virtual machine in East US to use the Recovery Services Vault in East US, and configure backup for the virtual machine in West US to use the Recovery Services Vault in West US.
Azure virtual machines can only be backed up to a Recovery Services Vault that resides in the same region. Therefore, the virtual machine in East US must be backed up to the vault in East US, and the virtual machine in West US must be backed up to the vault in West US.

Step-by-Step Solution

1
Determine the region of the source virtual machines.
The application virtual machine is in East US and the web virtual machine is in West US.
Azure Recovery Services Vault backups are bound by regional constraints.
2
Verify the region of the available Recovery Services Vaults.
One vault is located in East US and the other vault is located in West US.
Target vaults must match the region of the resources they back up.
3
Align the resources with the correct vault based on their regional locations.
Associate the application virtual machine with the vault in East US, and associate the web virtual machine with the vault in West US.
This matches the regional requirement for Recovery Services Vault backup operations.

Key Concept

Azure Recovery Services Vaults require that target virtual machines and the vault reside in the same Azure region to configure and perform backups.
