I'm just glad the frame didn't try to check into a hotel. That would be a real MAC address problem!

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

This question is a real brain-teaser. I'm going to go with C. Saving the source MAC and flooding the frame seems like the most logical approach.

Hmm, I think B is the right answer. The switch will save the source MAC address and discard the frame. Simple enough!

I'm pretty sure it's option D. The switch should save both the source and destination MAC addresses in the MAC FDB and flood the frame to all ports.

It can potentially create congestion, but switches are designed to handle it efficiently.

Doesn't flooding the frame to all ports create network congestion?

Yes, that's correct. It floods the frame to all ports to try and reach the destination.
