CompTIA Cloud+ (CV0-003) — Question 255

A systems administrator is implementing a new version of a company’s primary human-resources application. An upgrade will be performed on the production server, as there is no development environment. The administrator needs to have a plan in case something goes wrong with the upgrade. Which of the following will work best to ensure a quick rollback in case an issue arises?

Answer options

• A. An application-level backup
• B. A production snapshot
• C. A full backup
• D. A differential backup

Correct answer: B

Explanation

A production snapshot allows the administrator to capture the entire state of the server at a specific point in time, making it the quickest way to revert back if the upgrade fails. While a full backup could also work, it typically takes longer to restore than a snapshot. An application-level backup may not include all necessary system states, and a differential backup would require a full backup to restore, adding complexity and time to the rollback process.
