This N10-009 practice question tests your understanding of network operations. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network administrator is preparing documentation for a new branch office. The administrator needs a diagram that shows the logical relationships between network devices and how VLANs are trunked over inter-switch links. Which type of document should be created?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Logical topology diagram
A logical topology diagram is the correct choice because it illustrates how devices communicate across the network, including VLAN assignments and trunk links (e.g., 802.1Q tagging) between switches. This diagram abstracts physical locations to show Layer 2 and Layer 3 relationships, such as which VLANs traverse which inter-switch links, making it ideal for documenting VLAN trunking and logical connectivity.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Network baseline
Why it's wrong here
A baseline is a performance measurement, not a diagram.
✗
Wiring diagram
Why it's wrong here
A wiring diagram shows physical cable runs and patch panels.
✗
Physical topology diagram
Why it's wrong here
Physical topology shows device locations and cabling, not logical VLAN trunking.
✓
Logical topology diagram
Why this is correct
A logical topology diagram displays addressing, VLANs, and routing paths, making it ideal for showing trunk links and VLAN assignments.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'physical topology' with 'logical topology,' assuming that a physical diagram can show VLAN trunking, but physical diagrams only depict hardware connections, not the logical VLAN paths or trunking relationships.

Detailed technical explanation
How to think about this question
Logical topology diagrams often include VLANIDs, trunk encapsulation (802.1Q), and spanning-tree root bridges to show traffic flow. In a real-world scenario, an administrator might use a logical diagram to verify that a new VLAN is correctly trunked across all switches, avoiding misconfigurations that could cause broadcast storms or segmentation failures. This diagram type is essential for troubleshooting Layer 2 loops and ensuring proper VLAN propagation via VTP or manual configuration.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
