CompTIA A+ Core 2 (220-1102) — Question 150

Which of the following is used to identify potential issues with a proposed change prior to implementation?

Answer options

• A. Request form
• B. Rollback plan
• C. End-user acceptance
• D. Sandbox testing

Correct answer: D

Explanation

Sandbox testing is the correct answer because it allows for a controlled environment to test changes without affecting the live system, helping to identify potential issues. The other options, while important, do not directly assess the impact of changes in a testing environment; for example, a rollback plan is meant for recovery after a change has caused issues, not for preemptive testing.
