Question 303 of 464
N10-009 Network Operations Practice Question
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?
⚠ Common exam trap
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.
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
✓
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.

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
A logical topology diagram provides an abstract, high-level view of the network's data flow, illustrating network segments, IP addressing schemes, VLAN configurations, and routing paths. This type of diagram focuses on how devices communicate logically rather than their physical placement or the actual cables connecting them. Consequently, it offers no insight into which physical patch panel port connects to a specific wall jack.
When this WOULD be correct
When the question asks which documentation shows how devices communicate on the network (e.g., 'Which diagram illustrates the data path between a switch and a router?').
- ✓
Cabling diagram
Why this is correct
A cabling diagram is the definitive documentation for tracing physical network connections. It meticulously maps specific ports on patch panels to corresponding wall jacks or other termination points, often including cable identifiers and lengths. This visual representation is crucial for quickly locating the physical path of a network drop, essential for troubleshooting connectivity issues or making infrastructure changes.
- ✗
Network baseline
Why it's wrong here
A network baseline establishes a historical record of normal network performance metrics, such as bandwidth utilization, latency, and error rates, over a period. While invaluable for identifying deviations that indicate performance problems or security incidents, it provides no information about the physical location or mapping of cabling infrastructure. Therefore, it cannot assist in physically locating a patch panel connection.
When this WOULD be correct
When the question asks for documentation to compare current network performance against a historical reference to identify anomalies or capacity issues, a network baseline is the correct choice.
- ✗
Rack diagram
Why it's wrong here
A rack diagram illustrates the physical arrangement of equipment within a server rack, detailing the placement of devices like switches, servers, and patch panels, along with their power and basic inter-device cabling. Although it shows where a patch panel is located within a rack, it typically does not extend to documenting the specific port-to-wall-jack mappings required to trace an individual physical patch connection. Its scope is equipment layout, not detailed horizontal cabling.
When this WOULD be correct
When the technician needs to identify the physical location of a specific patch panel or switch within a rack, such as determining which rack unit contains a device for troubleshooting or replacement.
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 diagramWrong answer — click to see why▾
Why this is wrong here
A logical topology diagram shows data flow and device connections (e.g., IP addresses, VLANs), not physical cabling paths between patch panels and wall jacks.
★ When this WOULD be the correct answer
When the question asks which documentation shows how devices communicate on the network (e.g., 'Which diagram illustrates the data path between a switch and a router?').
Why candidates choose this
Candidates confuse 'logical' with 'physical' documentation, assuming any network diagram will show cable connections.
✗Network baselineWrong answer — click to see why▾
Why this is wrong here
A network baseline documents normal performance metrics (e.g., bandwidth utilization, latency), not physical connectivity between patch panels and wall jacks.
★ When this WOULD be the correct answer
When the question asks for documentation to compare current network performance against a historical reference to identify anomalies or capacity issues, a network baseline is the correct choice.
Why candidates choose this
Candidates may confuse 'baseline' with any foundational documentation, mistakenly thinking it includes physical cabling records.
✗Rack diagramWrong answer — click to see why▾
Why this is wrong here
A rack diagram shows the physical layout of equipment in a rack, not the cabling path from a patch panel to a wall jack. It does not map specific ports to remote locations.
★ When this WOULD be the correct answer
When the technician needs to identify the physical location of a specific patch panel or switch within a rack, such as determining which rack unit contains a device for troubleshooting or replacement.
Why candidates choose this
Candidates may confuse rack diagrams with cabling documentation, assuming that the physical arrangement of patch panels in a rack also indicates port-to-jack connections.
