Refer to the exhibit. The MAC address table is shown in its entirety. The Ethernet frame that is shown arrives at the switch. What two operations will the switch perform when it receives this frame? (Choose two.)
正解:D,E
Explanation/Reference: Explanation: If the switch already has the MAC address in its table for the destination, it will forward the frame directly to the destination port. If it was not already in its MAC table, then the source MAC is added to the MAC address table and frame would have been flooded out all ports except for the port that it came from.
