- A
Physical topology diagram
Why wrong: Physical topology diagrams focus on devices, cabling, and physical connectivity, not logical groupings like VLANs and subnets.
- B
Logical topology diagram
Logical topology diagrams show network segments, virtual LANs, IP addressing schemes, and routing – perfect for documenting VLAN and subnet relationships.
- C
Wiring diagram
Why wrong: Wiring diagrams detail cable runs, patch panel connections, and termination points, not logical VLAN/subnet associations.
- D
Rack elevation diagram
Why wrong: Rack elevation diagrams show the physical placement of equipment in racks, including ports and slot positions, but do not depict logical network segmentation.
Question 107 of 520
N10-009 Network Operations Practice Question
This N10-009 practice question tests your understanding of network operations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 creating documentation for a new data center. Which type of diagram is BEST for showing the logical relationships between VLANs and their associated subnets?
Answer choices
Why each option matters
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 the mapping of VLANs to their associated IP subnets. This type of diagram abstracts away physical cabling and device locations to focus on Layer 2 and Layer 3 relationships, such as VLAN IDs, subnet masks, and default gateways. It is essential for documenting network segmentation and troubleshooting inter-VLAN routing.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Physical topology diagram
Why it's wrong here
Physical topology diagrams focus on devices, cabling, and physical connectivity, not logical groupings like VLANs and subnets.
When this WOULD be correct
When the question asks for the best diagram to show the physical placement of servers, switches, and cabling paths in a data center.
- ✓
Logical topology diagram
Why this is correct
Logical topology diagrams show network segments, virtual LANs, IP addressing schemes, and routing – perfect for documenting VLAN and subnet relationships.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Wiring diagram
Why it's wrong here
Wiring diagrams detail cable runs, patch panel connections, and termination points, not logical VLAN/subnet associations.
When this WOULD be correct
When documenting physical cable runs between patch panels and switches in a data center, a wiring diagram is the best choice.
- ✗
Rack elevation diagram
Why it's wrong here
Rack elevation diagrams show the physical placement of equipment in racks, including ports and slot positions, but do not depict logical network segmentation.
When this WOULD be correct
When the question asks for the physical arrangement of servers, switches, and other hardware within racks in a data center, a rack elevation diagram is the best choice.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The N10-009 exam frequently reuses these exact scenarios with slightly different constraints.
✓Logical topology diagramCorrect answer▾
Why this is correct
Logical topology diagrams show network segments, virtual LANs, IP addressing schemes, and routing – perfect for documenting VLAN and subnet relationships.
✗Physical topology diagramWrong answer — click to see why▾
Why this is wrong here
A physical topology diagram shows the physical layout of devices and cabling, not logical relationships like VLAN-to-subnet mappings.
★ When this WOULD be the correct answer
When the question asks for the best diagram to show the physical placement of servers, switches, and cabling paths in a data center.
Why candidates choose this
Candidates may confuse 'logical' with 'physical' or think VLANs are tied to physical connections, overlooking that VLANs are logical constructs.
✗Wiring diagramWrong answer — click to see why▾
Why this is wrong here
A wiring diagram shows physical cable connections and paths, not logical relationships like VLAN-to-subnet mappings.
★ When this WOULD be the correct answer
When documenting physical cable runs between patch panels and switches in a data center, a wiring diagram is the best choice.
Why candidates choose this
Candidates may confuse 'wiring' with 'logical connections' because VLANs are often associated with switch configurations that involve cabling.
✗Rack elevation diagramWrong answer — click to see why▾
Why this is wrong here
A rack elevation diagram shows the physical placement of equipment in racks, not logical relationships between VLANs and subnets.
★ When this WOULD be the correct answer
When the question asks for the physical arrangement of servers, switches, and other hardware within racks in a data center, a rack elevation diagram is the best choice.
Why candidates choose this
Candidates may associate data center documentation with rack layouts and mistakenly think rack elevation diagrams include logical network information.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'logical topology' with 'physical topology,' assuming that a physical diagram can show VLANs because VLANs are configured on physical switches, but VLANs are a Layer 2 abstraction that must be documented separately.
Trap categories for this question
Command / output trap
Rack elevation diagrams show the physical placement of equipment in racks, including ports and slot positions, but do not depict logical network segmentation.
Detailed technical explanation
How to think about this question
In practice, a logical topology diagram for VLANs would include the VLAN ID (e.g., VLAN 10), its associated subnet (e.g., 192.168.10.0/24), and the default gateway (e.g., 192.168.10.1) on the Layer 3 switch or router. This mapping is critical for configuring 802.1Q trunking and ensuring proper traffic isolation. A real-world scenario might involve a misconfigured VLAN-to-subnet mapping causing hosts to receive an IP from the wrong DHCP scope, leading to connectivity failures that are only visible on the logical diagram.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
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.
