CompTIA A+ Core 1 (220-1101) — Question 440

A user reported performance issues on a computer after a recent OS update. A technician is confident that rolling back the system will resolve the issue. Which of the following steps should the technician take next?

Answer options

• A. Document the findings.
• B. Perform a system backup.
• C. Initiate the system restore.
• D. Verify full system functionality.

Correct answer: B

Explanation

Creating a system backup is crucial before making any changes, such as rolling back the OS, to ensure that data is not lost during the process. Documenting findings and verifying system functionality are important but should be done after a backup is created. Initiating the system restore without a backup could result in data loss if something goes wrong.
