A technician is troubleshooting a newly installed cable in an office building that has not yet been labeled. The cable's endpoint is hidden in a bundle with numerous other cables in a patch panel. Which tool should the technician use to correctly identify the endpoint of this specific cable from the bundle?
A toner probe is the correct answer because it is specifically designed to trace and locate the ends of specific cables within a group. The toner part sends a signal down the wire, and the probe part is used to scan along the cable bundle until a tone is detected, indicating the matching cable. A Time-domain reflectometer (TDR) would not be practical in this scenario as it is used primarily to diagnose the length of cables and find faults. A cable tester requires both ends of a cable to be accessible and is not intended for locating a cable within a bundle. A punchdown tool is used for inserting and securing wire terminations, not for tracking cable endpoints.
