  B. The switch will discard the frame and send an error message back to host A.
  C. The switch will flood the frame out of all ports except for port Fa0/3.
  D. The switch will add the destination address of the frame to the MAC address table and forward the frame to host D.
  A. The switch will add the source address and port to the MAC address table and forward the frame to host D.
