CompTIA Cloud+ (CV0-003) — Question 282

A systems administrator is patching virtual servers in a private cloud environment and must ensure any failure induced by patching is resolved as soon as possible. Which of the following is the best method for addressing this issue?

Answer options

• A. Uninstalling patches if the server is unresponsive after being patched
• B. Taking a full backup before patching and restoring from backup if the server is unresponsive after being patched
• C. Taking a snapshot before patching and reverting to the snapshot if a server is unresponsive after being patched
• D. Sending an alert to the on-call engineer if patching on a server fails for any reason

Correct answer: C

Explanation

The correct answer is C because taking a snapshot allows for a quick rollback to the exact state of the server before the patch was applied, minimizing downtime. Option A is inadequate as it only resolves the issue after it occurs, and B, while safe, is more time-consuming than using a snapshot. Option D does not directly resolve the issue but instead escalates it without providing an immediate solution.
