Which diagram shows the actual physical locations of devices and how cables are run between them?

• A. Network Diagram
• B. Physical Diagram
• C. Logical Diagram
• D. Rack Diagram

Answer: (B)

A physical diagram focuses on where devices actually sit in real space and how cables run between them. It provides the spatial layout—which room or area each device is in, where racks or cabinets are placed, and the exact paths cables traverse (through racks, cable trays, walls, or floors). This is crucial for installation, cable management, and future maintenance since you can plan routes, avoid congestion, and ensure accessibility and cooling. In contrast, a network diagram shows how devices are connected in a topology without implying precise locations, a logical diagram maps data flows and addressing rather than physical placement, and a rack diagram details equipment inside a single rack rather than the broader facility layout and cabling paths.
