Computer Networking 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? Flood the network with the frame Discard it and send an error message back to the originating host Add the source address and port to the MAC address table and forward the frame out the destination port Add the destination to the MAC address table and then forward the frame Flood the network with the frame Discard it and send an error message back to the originating host Add the source address and port to the MAC address table and forward the frame out the destination port Add the destination to the MAC address table and then forward the frame ANSWER DOWNLOAD EXAMIANS APP
