Question

Before a major OS upgrade, admins want an identical copy of a tax-system VM for rollback testing. Which virtualization operation should they use?

Accepted Answer

Clone the VM to create a duplicate instance for testing and potential rollback. — Cloning is photocopying the VM before you paint the walls—if the upgrade looks awful, the copy is still there. Do not delete the original hoping memory remembers it. Duplicate first, experiment second.

Answer

Delete the original VM and rebuild it from memory after the upgrade completes.

Answer

Enable hardware pass-through of a USB license dongle to every host in the cluster.

Answer

Shrink the VM to a single vCPU so the upgrade cannot modify disk contents.
