When isolating a physical-layer fault, which approach best helps identify the faulty component?

  1. A

    Replace the cable and switch port at the same time.

  2. B

    Assume the switch is faulty before checking the connection.

    Use any fiber type as long as the connectors fit.

  2. B

    Confirm that the fiber type and transceivers match the equipment and intended link.

  3. C

    Replace the patch panel without checking the transceivers.

A device has no link. Which checks are appropriate early in troubleshooting? Select all that apply.

  1. A

    Check that devices are powered.

  2. B

    Check that connections are seated and ports are correctly selected.

  3. C

    Assume the network is unavailable because there is no link light.

  4. D

    Check whether the ports are enabled.

  5. E

    Confirm that the cable type is suitable and include both ends of the path.

A connection passes through a wall jack and patch panel. Which part should be tested if the fault may be in the building cabling?

  1. A

    Test only the patch cord at the workstation.

  2. B

    Check only whether the switch has a link light.

  3. C

    Test the cabling run through the wall jack or patch panel.

A device has no link. After you replace its patch cable with a known-good cable of the correct type, the link light comes on. What is the most likely conclusion?

  1. A

    The switch port is definitely faulty.

  2. B

    The original patch cable is likely faulty.

  3. C

    The in-wall run must be replaced.

  4. D

    The device must be unpowered.

  2. B

    The original patch cord is likely faulty.

  3. C

    The in-wall run is definitely faulty.

  1. A

    The cable is certified for its intended Ethernet speed.

  2. B

    The cable has no faults of any kind.

  3. C

    The conductors reach the expected pins, but performance is not necessarily verified.

  4. D

    The cable is safe to test while carrying live network service.

A network link remains lit, but performance is poor and the connection repeatedly drops and returns. What is a sensible next step?

  1. A

    Inspect for cable or termination problems and check interface counters for errors.

  2. B

    Treat the link light as proof that the cabling is error-free.

  3. C

    Replace the transceivers before checking the cable or port.
