Show answer and explanation

Correct answer: C

Explanation

A blinking amber link light is a common indicator that the device is attempting to negotiate a connection but is failing to do so. This could be due to mismatched speeds, duplex settings, or a misconfiguration in the network. Understanding link light statuses is critical for effective network troubleshooting.

  • A. Incorrect.

    A completely unlit link light typically indicates that the cable is not connected properly or that there is no power to the device.

  • B. Incorrect.

    A solid amber light usually represents a hardware failure or an issue with the port itself, not a blinking amber light.

  • C. Correct.

    A blinking amber light indicates that the device is attempting to establish a connection but has not yet succeeded. This is common during the negotiation phase or when there is a network misconfiguration.

  • D. Incorrect.

    If the Ethernet connection is functioning normally, the link light would typically be solid green or blinking green, depending on the device and manufacturer, and not amber.
