D is just wrong, multicast shouldn't be dropped.

I’m a bit confused about whether all traffic gets dropped or just unicast. I think option D sounds extreme, but I can't recall for sure.

I practiced a similar question where we discussed how unknown multicast and broadcast traffic is handled. I feel like option E might be correct too.

I think if the unicast source address isn't in the forwarding database, the frame gets dropped. That sounds like option B to me.

I remember something about how the "discard-unknown" command affects traffic, but I'm not sure if it applies to broadcast traffic.

I've got a good handle on this. I think the correct answers are B and C, since the "discard-unknown" command will drop frames with unknown unicast destinations or sources.

Based on my understanding, if the unicast DA is not learned in the FDB, the frame will be dropped. But I'm not sure about the other options.

I'm a bit confused about the difference between unicast SA and unicast DA. I'll need to review those concepts before answering.

Okay, let's think this through step-by-step. The key is to focus on what happens to different types of traffic when the "discard-unknown" command is enabled.

I'm going with B and C. Seems like the 'discard-unknown' command is all about unicast addresses, not broadcast or multicast. Something tells me D is just trying to trick us.

D sounds like the most comprehensive answer, but I'm guessing that's not the right one. This 'discard-unknown' thing is really throwing me off.

I think B and C are the correct answers. If the unicast source or destination address is not in the FDB, the frame will be dropped due to the 'discard-unknown' command.

But if we enable 'discard-unknown' at the VPLS level, wouldn't it make sense for unicast traffic to be dropped if not in the FDB?
