If the MAC address is not learned, the switch cannot forward frames to that port.Final Answer:
The MAC address of the device is not learned by the switch. -> Option BQuick Check:
Switch forwarding depends on MAC learning = The MAC address of the device is not learned by the switch. [OK]
Quick Trick: Switch forwards only to learned MAC addresses [OK]
Common Mistakes:
MISTAKES- Blaming IP address for switch forwarding
