Free CompTIA Network+ N10-008 Practice Question

A network administrator notices that two switches are not communicating properly over a newly installed fiber link. The link lights are lit on both switches, indicating that there is a physical layer connection. However, no data is being transmitted between the switches. The administrator suspects that the transmit and receive pairs might be reversed during the installation of the fiber connectors. Which of the following actions should the administrator take to confirm and correct the issue?

  • Swap the fiber strands on one end of the connection.

  • Configure the switch ports to auto-negotiate the TX and RX signals.

  • Update the firmware on the switches to ensure compatibility with the fiber modules.

  • Install a fiber repeater to boost the signal between the switches.

  • Replace the fiber connectors as they may be damaged.

  • Use a tone generator and probe to determine if there is a signal on the fiber cable.
