The correct answer is the logical topology diagram. This is the right choice because a logical topology diagram documents the abstract, Layer 3 elements of a network—specifically the IP addressing scheme, VLAN assignments, and routing protocols—showing how data flows between devices regardless of their physical locations. On the CompTIA Network+ N10-009 exam, this question tests your ability to distinguish between logical and physical documentation; a common trap is confusing it with a physical topology diagram, which shows cable runs and device placement, not IP schemes or VLANs. For exam day, remember that if the documentation involves IP addresses, subnets, VLAN IDs, or routing protocols like OSPF, you are dealing with logical topology. A simple memory tip: “Logical is for Layers—IP, VLANs, and routing protocols live at Layers 2 and 3.”
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 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 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 correct because it documents the IP addressing scheme, VLAN assignments, and routing protocols—abstract elements that define how data flows through the network, independent of physical device locations. This type of diagram is essential for troubleshooting Layer 3 issues and planning changes to the network's logical design.
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.
✗
Physical topology diagram
Why it's wrong here
A physical diagram shows physical connections and device locations, not IP addressing or VLAN assignments.
✓
Logical topology diagram
Why this is correct
A logical diagram represents the network as seen by the OSI Layer 3, including IP subnets, VLANs, routing protocols, and logical connections.

✗
Rack elevation diagram
Why it's wrong here
A rack elevation diagram shows the physical placement of devices in a rack, not logical network information.
✗
Cable management plan
Why it's wrong here
A cable management plan documents the physical cabling infrastructure, not IP schemes or VLANs.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between physical and logical documentation by describing a scenario that mixes physical and logical elements, leading candidates to mistakenly choose a physical topology diagram when the question explicitly asks for IP schemes and VLANs.
Trap categories for this question
Command / output trap
A physical diagram shows physical connections and device locations, not IP addressing or VLAN assignments.
Detailed technical explanation
How to think about this question
Logical topology diagrams often include OSPF areas, BGP AS numbers, VLANIDs (802.1Q), and subnet masks (e.g., /24 or 255.255.255.0) to represent Layer 2 and Layer 3 segmentation. In a real-world scenario, a network engineer troubleshooting a routing loop would reference the logical diagram to verify OSPF neighbor relationships and redistribution points, not the physical cabling.

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.

Variation 1. 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?
medium
A.Network baseline
B.Wiring diagram
C.Physical topology diagram
✓ D.Logical topology diagram
Why D: 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.
