Difficulty: MediumRecovery Services Vaults and Backup Vaults

Your company has an Azure subscription named Sub-Corp-Ops that contains the resources shown in the following table:

Resource NameResource TypeAzure Region
VM-App-01Virtual machineeastus2
Disk-Data-01Azure Diskwestus3
Files-Config-01Azure File shareeastus2

You have the following vault resources:

Vault NameVault TypeAzure Region
RSV-EastRecovery Services Vaulteastus2
RSV-WestRecovery Services Vaultwestus3
BV-EastBackup Vaulteastus2
BV-WestBackup Vaultwestus3

You need to configure Azure Backup for VM-App-01, Disk-Data-01, and Files-Config-01. The solution must minimize the number of vaults used.

Which two vaults should you use?

  1. RSV-EastAnswer
  2. B
    RSV-West
  3. C
    BV-East
  4. BV-WestAnswer

Answer

RSV-East and BV-West
The correct vaults are RSV-East and BV-West. RSV-East (a Recovery Services Vault in eastus2) is required because both VM-App-01 and Files-Config-01 reside in eastus2 and require a Recovery Services Vault. BV-West (a Backup Vault in westus3) is required because Disk-Data-01 resides in westus3 and Azure Disk backup is supported only by Backup Vaults, which must match the resource region.

Step-by-Step Solution

1
Determine the backup vault requirements for the virtual machine (VM-App-01) and Azure File share (Files-Config-01).
Both resources are in the eastus2 region and must be backed up using a Recovery Services Vault in the same region. This requires RSV-East.
Azure Virtual Machines and Azure Files backups are supported by Recovery Services Vaults and must reside in the same region as the source resources.
2
Determine the backup vault requirements for the Azure Disk (Disk-Data-01).
The resource is in the westus3 region and must be backed up using a Backup Vault in the same region. This requires BV-West.
Azure Disk backup is supported by Backup Vaults (not Recovery Services Vaults) and the vault must reside in the same region as the disk.
3
Combine the requirements to find the minimum set of vaults.
Using RSV-East and BV-West satisfies all backup and regional requirements with exactly two vaults.
This configuration uses the minimum number of vaults required while complying with both workload type and regional constraints.
