David is working as a network administrator at his organization. One of the switches on his network has a port status LED that is alternating between green and amber. What could this indicate?
  1. There is a problem with the switch.
  2. The port is in STP blocking mode.
  3. The switch is operating normally.
  4. The port is shut down.
Explanation
Answer - A - If the light on the port keeps blinking between green and amber, it means that there is a problem with the switch.

Key Takeaway: When a switch port is connected, it first toggles between orange and amber. Then a stable green is established. If the light on the port keeps blinking, then it indicates there is an issue with the connection or the switch.
