Certified Information Systems Auditor (CISA) — Question 272

Which type of testing is MOST important to perform during a project audit to help ensure business objectives are met?

Answer options

• A. Regression testing
• B. Pilot testing
• C. Functional testing
• D. System testing

Correct answer: C

Explanation

Functional testing is essential during a project audit as it verifies that the system operates according to the specified requirements, directly impacting business objectives. Regression testing and system testing, while important, focus on different aspects and may not directly validate the fulfillment of business goals. Pilot testing is typically conducted to assess usability and performance in a real-world scenario, but it does not ensure that all functional requirements are met.
