CompTIA Cloud+ (CV0-003) — Question 205

A systems administrator is performing an OS upgrade on a production VM. Which of the following actions should the administrator take before the upgrade to ensure the FASTEST recovery of the system in case the upgrade fails in an unrecoverable way?

Answer options

• A. Submit the upgrade to the CAB.
• B. Perform a full backup.
• C. Take a snapshot of the system.
• D. Test the upgrade in a preproduction environment.

Correct answer: C

Explanation

Taking a snapshot of the system allows the administrator to quickly revert back to the previous state if the upgrade fails, making it the fastest recovery option. While submitting the upgrade to the CAB, performing a full backup, and testing in a preproduction environment are important steps, they do not provide the same immediate restoration capability as a snapshot.
