Certified Information Systems Auditor (CISA) — Question 156

Which of the following is the BEST source of information for assessing the effectiveness of IT process monitoring?

Answer options

• A. Performance data
• B. Participative management techniques
• C. Quality assurance (QA) reviews
• D. Real-time audit software

Correct answer: A

Explanation

Performance data provides quantitative metrics that directly reflect the effectiveness of IT process monitoring, making it the best choice. While participative management techniques, QA reviews, and real-time audit software can offer insights, they do not provide the same level of direct measurement and analysis as performance data.
