A network administrator needs to create a diagram that shows the IP addressing scheme, VLAN assignments, and routing protocols used in the network. This diagram will be used for troubleshooting and future planning. Which type of documentation should the administrator create?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Physical topology diagram
A physical diagram shows physical connections and device locations, not IP addressing or VLAN assignments.
B
Best answer
Logical topology diagram
A logical diagram represents the network as seen by the OSI Layer 3, including IP subnets, VLANs, routing protocols, and logical connections.
C
Distractor review
Rack elevation diagram
A rack elevation diagram shows the physical placement of devices in a rack, not logical network information.
D
Distractor review
Cable management plan
A cable management plan documents the physical cabling infrastructure, not IP schemes or VLANs.
Common exam trap
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Technical deep dive
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
- Access ports place end devices into a single VLAN.
- Trunk ports carry multiple VLANs between switches.
- Allowed VLAN lists decide which VLANs can cross a trunk.
- Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
- Use show vlan brief to verify access VLANs.
- Use show interfaces trunk to verify trunk state and allowed VLANs.
- Do not treat every same-VLAN issue as a routing problem.

FAQ
Questions learners often ask
What does this N10-009 question test?
Access ports place end devices into a single VLAN.
What is the correct answer to this question?
The correct answer is: Logical topology diagram — Network documentation is typically divided into physical and logical diagrams. A logical topology diagram shows how data flows through the network, including IP addresses, VLANs, subnets, routing protocols, and network segments. Physical topology diagrams show cables, devices, and physical locations. Rack elevation diagrams show equipment placement in racks. Cable management plans detail cabling paths. For IP schemes and VLANs, a logical diagram is appropriate.
