Which diagram shows the physical arrangement of equipment in server racks, measured in rack units (U)?

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

Answer: (C)

Rack height units (U) and physical placement are what this topic centers on. A diagram that shows how hardware is arranged inside server racks uses rack units to describe the height each device occupies, guiding how many devices fit, how they’re stacked, and how they fit into the physical cabinet. This helps with planning space, airflow, cooling, weight distribution, and cabling. Other diagram types focus on connections or logical relationships rather than the physical mounting heights, so they don’t convey the actual rack layout or device heights in U.
