There is a network (RJ45) port in your office, recently it stopped working. There is no connectivity provided when you plugin to it. The cable and your NIC are known-good, you need to make sure the cable on the back-end of the port is connected but the wiring closet is a disaster. Which tool will assist with this?

  • PING
  • Tone generator/probe
  • Cable tester
  • Loopback plug
