The correct answer is B. Restore the snapshot. When a virtualized machine's snapshot exists, restoring it returns the VM to the exact saved state, including all configuration prior to any changes made to the underlying physical hardware.

Question

An administrator has virtualized a physical server. The application team reports satisfactory performance. The physical machine has been reimaged with a newer operating system. The following day, the application team remembers that the physical server had a dual purpose and uses a proprietary telephony card that connects to the PBX switch. The administrator needs to restore the server to its previous state. Which of the following should the administrator perform?

Options

  • AP2P
  • BRestore the snapshot
  • CV2V

Why each option

When a virtualized machine's snapshot exists, restoring it returns the VM to the exact saved state, including all configuration prior to any changes made to the underlying physical hardware.

AP2P

P2P (Physical to Physical) refers to cloning or migrating one physical machine to another physical machine and is not applicable when the source is already a virtual machine.

BRestore the snapshotCorrect

Restoring a snapshot reverts the virtual machine to its exact state at the time the snapshot was captured - before the physical server was reimaged - recovering all OS configuration, application data, and settings. This is the fastest and most direct way to bring back the previous server environment without complex migration steps. The snapshot preserves the complete disk and memory state, effectively undoing the changes caused by the reimage.

CV2V

V2V (Virtual to Virtual) migrates a VM from one hypervisor platform to another and does not restore a previous state - it would still reflect the current, post-reimage configuration.

DV2P

V2P (Virtual to Physical) converts a virtual machine back to a physical deployment, which is a lengthier process and not the most efficient approach when a snapshot of the desired state already exists.
