You want to confirm each cable lands on the planned port. What do you do?
Why B is the answer
Compare discovered neighbors with the cabling map
Topology data shows what is really connected.
In detail
- Discovered neighbors show what is really connected.
- Automate the comparison.
Use case
An illustrative scenario, not a real incident.
Discovered neighbors show one cable in the wrong port, which the cabling map reveals.

Q{"Does the neighbor match the plan?"}
Q -->|"Yes"| A0["Continue"]
Q -->|"No"| A1["Fix the cable"]Key point: Compare neighbors with the map.
Why the other options are wrong
- A. Trust the installer's sign-off sheet
- A sign-off sheet is not evidence.
- C. Check only that each link light is on
- A light shows a link, not the right port.
- D. Run HPL once and then assume all links are right
- Performance may hide a miswire.
