I'm going with C. The switch should forward the multicast frame based on the known source in the forwarding table, right?

I'm not sure about this one. I was thinking it might be B, since the switch has to flood the multicast frame like an unknown unicast destination.

Hmm, this is tricky. I think the answer is A, since the switch should forward the multicast frame based on the known destination in the forwarding table, just like a unicast frame.

I agree with Mattie. When forwarding a multicast frame, the switch should behave like it's forwarding a unicast frame with a known destination.
