Options
- ARestarting the virtual server
- BCreating a snapshot
- CCreating an open virtualization format

Explanation
Before applying a critical patch to a virtual server, creating a snapshot is the best practice as it allows for immediate rollback to the pre-patch state if issues arise.
Common mistakes.
- A. Restarting the virtual server before a patch might be part of a maintenance window but does not provide a rollback mechanism if the patch fails.
- C. Creating an Open Virtualization Format (OVF) template is used for exporting and importing VMs, often for migration or archival, not for a quick rollback point before patching.
- D. Creating a copy of important files is a good general backup practice, but a server snapshot provides a complete system-level rollback capability which is more comprehensive and faster than restoring individual files for a critical system patch.
