Exam N10-009 topic 1 question 39 discussion

A. toner Generic term for two devices used together—a tone generator and a tone locator (probe)—to trace cables by sending an electrical signal along a wire at a particular frequency. The tone locator then emits a sound when it distinguishes that frequency. Also referred to as Fox and Hound

Toner is the easiest tool to identify the appropriate patch panel port

A toner (also known as a tone generator and probe) is the easiest tool to use for identifying the appropriate patch panel port when the ports are not labeled. It works by sending a tone down the cable, which can be traced with the probe at the other end, helping the technician quickly identify the corresponding patch panel port.

C, Cable tester. In this scenario a cable tester can verify the connectivity of one end of the cable, while you can test each of the ports of the patch panel to see where the connection is easily. A Toner on the other hand (I think they are trying to refer to a tone generator probe?) Would not work as well, since you'd send a signal down a cable, and test for an already patched cable to be giving off the tone for the probe to read.
