The answer is the cabling diagram. This is the correct choice because a cabling diagram documents the physical layer (Layer 1) of the network, detailing exactly how cables are run, terminated, and labeled—including which patch panel port in the server room maps to a specific office wall jack. In contrast, a logical topology focuses on data flow, IP addressing, and virtual connections, which would be useless for tracing a physical cable path. On the CompTIA Network+ N10-009 exam, this question tests your ability to distinguish between physical and logical documentation; a common trap is confusing the cabling diagram with a network map or logical topology diagram. Remember the memory tip: “Cabling is physical, topology is logical”—if you need to touch the wire or find the port, you need the cabling diagram.
N10-009 Network Operations Practice Question
This N10-009 practice question tests your understanding of network operations. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 technician needs to find which physical patch panel port in the server room connects to a specific office wall jack. Which type of network documentation should the technician consult?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cabling diagram
A cabling diagram provides the physical layer (Layer 1) documentation that maps specific patch panel ports to wall jacks, including cable runs, termination points, and labeling. This is exactly what the technician needs to trace the physical connection from the server room patch panel to the office wall jack.
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.
✗
Logical topology diagram
Why it's wrong here
Logical diagrams depict network segments, IP addresses, and routing, not physical cabling connections.
✓
Cabling diagram
Why this is correct
Cabling diagrams document the physical cabling infrastructure, including identifiers for patch panels, wall jacks, and cables.

✗
Network baseline
Why it's wrong here
A baseline is a record of normal network performance metrics, not physical connectivity.
✗
Rack diagram
Why it's wrong here
Rack diagrams show the placement of equipment in a rack but usually do not provide the detailed patch panel-to-wall jack mappings.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between physical and logical documentation, and the trap here is that candidates confuse a logical topology diagram (which shows data flow) with a cabling diagram (which shows physical connections), leading them to select A instead of B.

Command / output trap
Rack diagrams show the placement of equipment in a rack but usually do not provide the detailed patch panel-to-wall jack mappings.
Detailed technical explanation
How to think about this question
Cabling diagrams often follow TIA/EIA-606 labeling standards, which assign unique identifiers to each patch panel port, cable, and wall jack. In a structured cabling system, the technician would use this documentation to cross-reference the wall jack ID (e.g., 'WJ-101') with the corresponding patch panel port (e.g., 'PP-1A-24') to locate the physical connection. Real-world scenarios may involve using a toner and probe to verify the cable if documentation is outdated, but the diagram itself is the primary reference.

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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
