Difficulty: MediumRecovery Services Vaults and Backup Vaults

Your company has two Azure subscriptions named Sub-Production and Sub-Management. The subscriptions contain the resources shown in the following table:

Resource NameResource TypeAzure RegionResource GroupSubscription

You need to configure backup for VM-App-East.

Which vault can you use to back up VM-App-East?

  1. Vault-RSV-East onlyAnswer
  2. B
    Vault-RSV-East or Vault-RSV-Central only
  3. C
    Vault-RSV-East or Vault-BV-East only
  4. D
    Vault-RSV-East, Vault-BV-East, or Vault-RSV-Central

Answer

Vault-RSV-East only
The correct answer is Vault-RSV-East only because backing up an Azure Virtual Machine requires a Recovery Services Vault located in the same region as the VM. VM-App-East is in the East US region, and Vault-RSV-East is the only Recovery Services Vault in that region. Cross-subscription backup is supported.

Step-by-Step Solution

1
Determine the resource type of VM-App-East and identify its backup vault compatibility.
VM-App-East is an Azure Virtual Machine, which can only be backed up to a Recovery Services Vault, not a Backup Vault.
Recovery Services Vaults support virtual machine backups, whereas Backup Vaults support other workloads like Azure Disks, Azure Blobs, and Azure Database for PostgreSQL.
2
Check the regional constraints for Azure Virtual Machine backups.
The Recovery Services Vault must be in the same region (East US) as VM-App-East.
Azure Backup requires that the virtual machine and the Recovery Services Vault reside in the same geographical region.
3
Filter the available vaults based on resource type, region, and subscription compatibility.
Only Vault-RSV-East matches all requirements (Recovery Services Vault in East US).
Although Vault-RSV-East is in a different subscription (Sub-Management) and resource group (RG-Backup-East), cross-subscription and cross-resource group backups are supported as long as the vault is in the same region as the VM.

Key Concept

Azure Virtual Machine backups require a Recovery Services Vault in the same region as the virtual machine.
