How is the diagram kept current per 1.1.2?

• A. The diagram is automatically updated by a tool.
• B. The diagram is archived in a locked cabinet.
• C. The diagram is published quarterly.
• D. Interview responsible personnel to verify that the diagram is kept current.

Answer: (D)

Keeping the network diagram up-to-date means there is an ongoing process tied to change management that ensures the diagram reflects the live environment whenever changes happen. Verifying this by interviewing the people responsible for maintaining the diagram is the best approach because it confirms there is accountability and a defined process for updates, not just a one-time or automated assumption. Automated updates aren’t enough on their own, since they require proper governance to ensure accuracy. Archiving the diagram or publishing it only quarterly would hide the current state or imply periodic, not continuous, accuracy, which wouldn’t meet the requirement to keep the diagram current.
