CompTIA Network+ (N10-009)Network OperationsEasy
A network administrator is reviewing the network documentation and finds a diagram that depicts the physical location of devices, cable runs between wiring closets, and rack elevations. What type of network diagram is the administrator examining?
- ALogical topology diagram
- BIP addressing scheme diagram
- CPhysical topology diagram
- DNetwork services diagram
Show answer & explanationAnswer & explanation
Correct answer: C. Physical topology diagram
A physical topology diagram illustrates the actual, tangible layout of network components, including device locations, cabling, and rack placements. This is distinct from logical diagrams that show how data flows.
Why the other options are wrong
- A. A logical topology diagram illustrates how data flows and devices communicate, often showing VLANs, subnets, and routing, not physical placement.
- B. An IP addressing scheme diagram details the allocation of IP addresses, subnets, and potentially VLANs, which is logical information.
- D. A network services diagram focuses on the services running on the network, such as DNS, DHCP, or web servers, and their interdependencies.
Physical Topology Diagram
A network diagram that illustrates the tangible layout of network devices, including their physical locations, the type and length of cables connecting them, and their arrangement within racks or cabinets.
- Shows real-world device placement.
- Details cable runs and connections.
- Useful for installation, troubleshooting hardware, and asset management.
Memory trick: Diagrams show logic or location, services or numbers.
