Which tool should a technician use to locate the physical connection when the wall jack and network patch panel do not have a label?

A tone generator is an essential tool for locating physical connections in network cabling. It works by sending a signal through the cable, which can then be detected using a tone probe or receiver. When both the wall jack and the network patch panel lack labels, the technician can connect the tone generator to one end of the cable and use the probe to trace the signal along the cable paths. This allows the technician to identify and pinpoint exactly where the cable runs, making it easier to confirm the connections without needing any existing labeling.

In contrast, a multimeter is typically used for measuring electrical properties like voltage, current, and resistance, which doesn't inherently help in tracing cable connections. A packet sniffer monitors the data transmitted over a network but does not provide any insights into the physical layout of the cabling itself. Lastly, a loopback adapter is used for testing the functionality of network interfaces but will not assist in identifying the path of a cable through the infrastructure.
