- C. It floods the frame out of all its interfaces except the interface on which the frame arrived.
- D. It transmits the frame out of the appropriate interface.
Answer : B
Question 14
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 floods the frame out of all ports except the port on which it was received.
- B. The switch looks in its FDB. If the source address is unknown it discards the frame.
- 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 destination address is unknown it floods the frame out all ports except the port on which it was received.
