I'm not sure, but I think the answer might be D) The source and destination MAC addresses are saved in the MAC FDB, and the frame is flooded to all ports.

I disagree, I believe the answer is C) The source MAC address is saved in the MAC FDB, and the frame is flooded to all ports except the receiving port.

Haha, this is a classic networking question. I'm going with B - the switch should save the source MAC address and then just discard the frame. Who needs to forward it, am I right?

No way, I'm going with B. The source MAC address is saved in the MAC FDB, and the frame is discarded.

D seems like the right answer to me. The switch should save both the source and destination MAC addresses and then flood the frame to all ports.

That makes sense. It's important for the switch to learn and update its MAC address table.

Yes, but it's necessary in this case to ensure that the frame reaches its destination.

That would be option B. The switch saves the source address and discards the frame.

But wouldn't flooding the frame to all ports cause unnecessary traffic on the network?

But what if the switch just saves the source address and discards the frame?

I think D is correct too. The switch needs to save both addresses and flood the frame.
