Difficulty: EasyDocumentation and Diagrams

A network engineer needs to document a newly expanded network segment connecting three branch offices. The documentation must clearly illustrate IP subnet ranges, gateway addresses, interface names, and dynamic routing protocol boundaries, without showing physical cable lengths or hardware rack locations. Which of the following documentation types is most appropriate for this requirement?

  1. Logical topology diagramAnswer
  2. B
    Physical topology diagram
  3. C
    Rack elevation diagram
  4. D
    Wiring schematic

Answer

Logical topology diagram
A logical topology diagram displays how data logically moves through a network. It includes critical network-layer details such as IP address schemes, subnet masks, default gateways, and routing protocol relationships, making it the correct document for mapping layer 3 architecture without detailing physical hardware placement.

Step-by-Step Solution

1
Identify the required elements to document
The requirements call for showing IP subnets, interface addresses, and routing protocol boundaries.
These elements pertain to network layer data paths and logical address structures rather than physical placement.
2
Compare document types against the requirements
Logical topology diagrams map out subnets, IP configurations, and routing protocols, while physical topology, rack diagrams, and wiring schematics focus on hardware layout and cabling.
Selecting a logical diagram satisfies the goal of illustrating data flow and addressing without clutter from physical hardware dimensions.
