If a switch receives a frame and the source MAC address is not in the MAC address table but the destination address is, what will the switch do with the frame?
Answer: Option
Explanation:
Since the source MAC address is not in the MAC address table, the switch will add the source address and the port it is connected to into the MAC address table and then forward the frame to the outgoing port.

I did not understand. If the destination MAC Address is present in the frame, then Switch will just forward the packet to that destination port. I don't believe that the Switch cares about the Source MAC Address as it may be coming in from another network and routed through the gateway router to the switch. Please correct me if I am wrong. [This is when the packet is coming from the trunk port on the switch].
