宛先 MAC アドレスが不明なフレームを受信したときのレイヤ 2 スイッチのデフォルトの動作は何ですか?
正解:B
If the destination MAC address is not in the CAM table (unknown destination MAC address), the switch sends the frame out all other ports that are in the same VLAN as the received frame. This is called flooding. It does not flood the frame out the same port on which the frame was received.
