Certified Information Systems Auditor (CISA) — Question 399

Which of the following would be MOST helpful to an IS auditor assessing the reliability of an organization’s network?

Answer options

• A. Protocol analyzer
• B. Online monitoring
• C. Downtime report
• D. Response time report

Correct answer: A

Explanation

A Protocol analyzer is essential for an IS auditor as it allows for detailed analysis of network traffic, helping to assess reliability. Online monitoring provides real-time insights but may not capture comprehensive data for reliability assessments. Downtime and response time reports are useful but are retrospective and do not provide the in-depth analysis needed for a full reliability evaluation.
