Question

A technician must trace a network cable from a user's desk to the punch down block in the wiring closet. Which of the following tools would be the BEST choice?

Options

ACable tester
BMultimeter
CLoopback plug
DToner probe

Explanation

A toner probe (also called a tone generator and probe kit) is the correct tool for tracing cables. The tone generator is connected to one end of the cable, and the inductive probe is used to detect the tone along the cable path or at the punch down block without needing physical access to both ends simultaneously. A cable tester checks continuity/wiring integrity but requires access to both ends. A multimeter measures electrical properties. A loopback plug tests port functionality - none of these help physically trace a cable's route.
