Certified Information Systems Auditor (CISA) — Question 612

Which of the following is MOST important when planning a network audit?

Answer options

• A. Isolation of rogue access points
• B. Identification of existing nodes
• C. Analysis of traffic content
• D. Determination of IP range in use

Correct answer: B

Explanation

The identification of existing nodes is essential as it helps to understand the current network structure and devices in use, which is critical for an effective audit. While isolating rogue access points, analyzing traffic content, and determining IP ranges are important tasks, they are secondary to having a clear inventory of all active nodes in the network.
