質問 2：
What is the behavior of a typical Ethernet switch when it receives a frame with a uncast destination MAC address? (Choose two.)
A. The switch looks in its FDB. If the destination address is unknown it discards the frame.
B. The switch looks in its FDB. If the destination address is unknown it floods the frame out all ports except the port on which it was received.
C. The switch looks in its FDB. If the destination address is known it forwards the frame out the appropriate interface.
D. The switch looks in its FDB. If the source address is unknown it discards the frame.
