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.
