CompTIA Project+ (PK0-005) — Question 149

A project is executed to migrate all data to a single system following the merger of two companies. The team validates that system performance will not be impacted. Which of the following did the team perform?

Answer options

• A. Regression testing
• B. Smoke testing
• C. Stress testing
• D. Automation testing

Correct answer: A

Explanation

The correct answer is A, as regression testing checks that new changes haven't adversely affected existing functionalities, ensuring system performance is maintained. Smoke testing is a preliminary check, stress testing evaluates performance under extreme conditions, and automation testing focuses on the execution of pre-scripted tests, none of which specifically validate existing performance after changes.
