CompTIA Security+ (SY0-501) — Question 486

A technician is required to configure updates on a guest operating system while maintaining the ability to quickly revert the changes that were made while testing the updates. Which of the following should the technician implement?

Answer options

• A. Snapshots
• B. Revert to known state
• C. Rollback to known configuration
• D. Shadow copy

Correct answer: A

Explanation

The correct answer is A, Snapshots, as they allow the technician to capture the current state of the guest OS and easily restore it later if needed. The other options, while related to system recovery, do not provide the same level of flexibility and immediacy in reverting to a previous state as snapshots do.
