You have a Recovery Services vault named RSV1. RSV1 has a backup policy that retains instant snapshots for five days and daily backup for 14 days.
RSV1 performs daily backups of VM1. VM1 hosts a static website that was updated eight days ago.
You need to recover VM1 to a point eight days ago. The solution must minimize downtime.
What should you do first?

A. Deallocate VM1.

B. Restore VM1 by using the Replace existing restore configuration option.

C. Delete VM1.

D. Restore VM1 by using the Create new restore configuration option.








 

Suggested Answer: B

Replace existing:
You can restore a disk, and use it to replace a disk on the existing VM.
The current VM must exist. If it's been deleted, this option can't be used.
Azure Backup takes a snapshot of the existing VM before replacing the disk, and stores it in the staging location you specify. Existing disks connected to the VM are replaced with the selected restore point.
The snapshot is copied to the vault, and retained in accordance with the retention policy.
After the replace disk operation, the original disk is retained in the resource group. You can choose to manually delete the original disks if they aren't needed.
