In the following figure, what will happen if the computers on ports Fa0/2 (Computer A) and Fa0/3 (Computer B) are swapped?

Computer A's frames will be forwarded to its new port of Fa0/3 since the entries will be cleared out when the cables are disconnected and relearned. When Computer A is disconnected from Fa0/2, the MAC address entries for that port will be cleared from the table. Therefore, frames will no longer be forwarded to Fa0/2 on behalf of Computer A, only to Computer A's new port of Fa0/3. Frames are only forwarded to all active ports when the destination MAC address in a frame is not in the MAC address table.
