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.
The correct answer according to book author is A and B
I selected only option B, because once switch has sent a frame of PC1 to PC2, now PC2 should be in its MAC table,
