What does a Network Diagram depict?

• A. A diagram showing system components and connections within a networked environment.
• B. The process of remoting scanning for vulnerabilities.
• C. A method of isolating cardholder data through segmentation.
• D. The protocol that synchronizes time.

Answer: (A)

A network diagram visually maps the components of a network and how they connect, showing devices, links, and data paths within an environment. This helps you identify where cardholder data flows and which systems touch it, so you can define the Cardholder Data Environment and apply appropriate controls. The other options describe actions or concepts unrelated to diagramming: vulnerability scanning is a security assessment process, segmentation is a data-isolation technique, and a time-sync protocol is about clock synchronization—not a diagram.
