CompTIA Project+ (PK0-005) — Question 181

After new capabilities were deployed in a system, issues with preexisting capabilities were reported. Which of the following testing cycles should be used to prevent this issue?

Answer options

• A. Performance testing
• B. User acceptance testing
• C. Stress testing
• D. Unit testing

Correct answer: B

Explanation

User acceptance testing (UAT) is designed to ensure that new changes do not negatively impact existing functionalities, making it the most suitable choice here. Performance testing, stress testing, and unit testing focus on different aspects, such as system load, breaking points, and individual components, but do not specifically verify user satisfaction with the overall system post-deployment.
