A technician is troubleshooting connectivity issues to a PC and needs to verify which cable is plugged into the correct port of the patch panel. What tool should the technician use?

The technician should use a cable tester to verify the connectivity of the cables connected to the patch panel. This tool can help identify which cable corresponds to which port and check for any faults or misconfigurations. Additionally, a tone generator and probe can be employed to trace the cable path more effectively.
