Which of the following is the BEST tool to verify the cable is plugged into the correct port on the patch panel?

A cable certifier measures whether a cable meets performance standards such as TIA/EIA categories, but does not trace or identify cable paths.

A punch down tool is used to seat wires into keystone jacks or patch panel ports, not to identify or trace cable paths.

A toner probe kit consists of a tone generator attached to one end of the cable and an inductive amplifier probe that audibly indicates when it is near the correct wire, even through walls and within cable bundles. This allows a technician to positively identify which port on a patch panel is connected to a specific outlet or drop, confirming correct termination. No other tool in the list provides this cable-tracing capability.

A cable tester verifies continuity and correct pin-to-pin wiring at both ends of an already-terminated cable, but cannot trace an unknown cable to a specific patch panel port.
