You are trying to make sense of server room where all the drops terminate, and you want to begin by labeling each drop in the server room with a room and letter number corresponding to its physical drop location in the building. What tool is going to be most helpful to you in completing this task?
  1. Cable Tester
  2. Loopback Plug
  3. Toner Probes
  4. Punch Down Tools
Explanation
Answer: C - Toner Probes will be most helpful to you in trying to locate the physical location of cables on a patch panel.

Key Takeaway: Toner Probes work by emitting a tone into the cable that can be recognized by a unit plugged into the other end of the cable. So, you can use this device to determine the location of cables that have been labeled poorly. A loopback plug tests a network card or Ethernet port, a cable tester tests the cable itself, and a punch down tool is used to terminate patch cables in a patch panel, for instance on an IDF or MDF.
