Show answer and explanation
Correct answer: B
Explanation
A solid amber link light on a switch port typically indicates a problem with the connection, such as a speed or duplex mismatch. This issue occurs when the switch and the connected device have incompatible configurations for speed or duplex settings. It is different from a green light, which indicates normal operation, or no light, which signals no connection.
- A. Incorrect.
A solid amber link light usually does not indicate that the port is administratively disabled. Administratively disabled ports are generally indicated by no light at all or specific configurations in the switch settings.
- B. Correct.
A solid amber link light often indicates a speed or duplex mismatch on the port. This can occur when the switch and the connected device are not configured to negotiate speed and duplex settings properly.
- C. Incorrect.
A solid amber link light does not indicate normal operation. A solid green or blinking green light typically signifies an active and properly functioning connection.
- D. Incorrect.
A solid amber link light does not indicate a disconnected or damaged cable. A disconnected cable usually results in no link light at all.
