Difficulty: MediumDocumentation and Diagrams

A network administrator is preparing updated documentation following the deployment of a new Layer 3 collapsed core network structure. The documentation must specifically detail IP address assignments, VLAN identifiers, subnet boundaries, and active routing protocol relationships across all virtual interfaces, while excluding physical cable routes and equipment rack positions. Which type of documentation is best suited for this requirement?

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

Answer

The logical topology diagram is the correct choice because it documents IP subnets, VLAN arrangements, and logical routing pathways independently of physical hardware locations.
The logical topology diagram is designed specifically to visualize how data flows through a network. It details IP addresses, subnet masks, VLAN names/numbers, virtual router interfaces, and dynamic routing protocols without cluttering the view with physical cable paths or hardware rack locations.

Step-by-Step Solution

1
Analyze the documentation requirements stated in the scenario
Identified the need to document IP addressing, VLAN IDs, subnet boundaries, and routing protocol interactions.
Determining whether the data represents physical placement or logical protocol flow dictates the proper diagram type.
2
Evaluate the difference between logical and physical network artifacts
Physical diagrams focus on cabling and hardware locations, whereas logical diagrams map software layer configurations and traffic paths.
Excluding cable runs and rack placement points directly away from physical topologies, wiring schematics, and rack diagrams.
3
Select the matching network documentation type
The logical topology diagram perfectly satisfies the requirement to illustrate network subnets, VLANs, and Layer 3 routing topology.
Logical diagrams represent the virtual organization of the network.
