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?
A. Discard it and send an error message back to the originating host
B. Flood the network with the frame
C. Add the source address and port to the MAC address table and forward the frame out the destination port
D. Add the destination to the MAC address table and then forward the frame
Answer: Option C
Solution(By Examveda Team)
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.What is the purpose of Spanning Tree Protocol in a switched LAN?
