 Discuss Question
Answer: Option B. -> show mac address-table
Question 720. 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?
  1.    Flood the network with the frame
  2.    Add the source address and port to the MAC address table and forward the frame out the destination port
  3.    Discard it and send an error message back to the originating host
