Question

Difficulty: MediumAzure Virtual Machine Recovery and Restore

An administrator manages an Azure virtual machine named vm-analytics that runs Windows Server 2022. The virtual machine has one OS disk and one data disk named disk-data-01, both of which are Azure Managed Disks. The virtual machine is backed up daily to a Recovery Services vault named vault-prod. The data disk disk-data-01 becomes corrupted due to a database write error. The administrator needs to restore the data disk to its state from a backup taken yesterday. The restore process must meet the following requirements:
- The virtual machine vm-analytics must remain online and continue serving users.
- The restored disk must be attached to vm-analytics as a new data disk to allow data verification.
- Administrative effort must be minimized.

Which recovery configuration should the administrator select in the Azure portal?

  1. Select the Restore disks option and set Restore as Managed Disks to Yes.Answer
  2. B
    Select the Replace existing option to swap the corrupted data disk directly.
  3. C
    Select the Restore disks option and set Restore as Managed Disks to No to restore the disks as VHDs in a staging storage account.
  4. D
    Select the File Recovery option and run the generated executable script on vm-analytics.

Answer

Select the Restore disks option and set Restore as Managed Disks to Yes.
Selecting the 'Restore disks' option with 'Restore as Managed Disks' set to 'Yes' restores the disks directly as Managed Disk resources in the specified resource group. This allows the administrator to attach the restored disk containing the data to the running virtual machine without interrupting the virtual machine's status, minimizing administrative effort.

Step-by-Step Solution

1
In the Azure portal, navigate to the backup items of the Recovery Services vault and select the restore point from yesterday.
The restore configuration page opens with options to recover the virtual machine.
This allows the selection of the restore point containing the uncorrupted data disk.
2
Select 'Restore disks' as the restore type and set 'Restore as Managed Disks' to 'Yes'.
Azure Backup restores the disks directly as Managed Disk resources in the specified resource group using the staging storage account.
Restoring directly as Managed Disks avoids the need to manually convert VHD files in a storage account into Managed Disks.
3
Attach the newly restored Managed Disk containing the data to the running virtual machine.
The disk becomes available to the operating system without shutting down the virtual machine.
This meets the requirement to keep the virtual machine online during verification.
