- 13.PC1, with MAC address 1111.1111.1111, is connected to Switch SW1’s Fa0/1 interface. PC2, with MAC address 2222.2222.2222, is connected to SW1’s Fa0/2 interface. PC3, with MAC address 3333.3333.3333, connects to SW1’s Fa0/3 interface. The switch begins with no dynamically learned MAC addresses, followed by PC1 sending a frame with a destination address of 2222.2222.2222. If the next frame to reach the switch is a frame sent by PC3, destined for PC2’s MAC address of 2222.2222.2222, which of the following are true?
- A.
The switch forwards the frame out interface Fa0/1.
- B.
The switch forwards the frame out interface Fa0/2.
- C.
The switch forwards the frame out interface Fa0/3.
- D.
The switch discards (filters) the frame.
