D seems off. The FDB should store local MACs too, right?

C is definitely true. Flooding is part of the process.

Wait, really? I thought the FDB was shared across all VPLSes.

I disagree, B is misleading. Each VPLS has its own FDB.
NO

A is correct! Mesh SDPs do help with MAC learning.

Option D seems off to me; I thought the FDB stored MAC addresses for both local and remote sites, not just remote ones.

I recall that mesh SDPs play a role in MAC learning, so option A might be correct, but I need to double-check that.

I'm not entirely sure about option B; I remember something about PEs having separate FDBs for different VPLSes, but it could be different.

I think option C sounds familiar because we discussed how broadcast and multicast frames are typically flooded in VPLS.
NO

Ah, I remember this from the lectures. The correct answer is C - frames received on a SAP that are broadcast, multicast or unknown are flooded. VPLS uses a Flood and Learn mechanism for MAC learning, so that's the key thing to remember here.

I'm a bit confused by this question. I know VPLS is a Layer 2 VPN technology, but the details of how MAC learning works are a bit hazy for me. I'll have to review my notes on this before answering.

Okay, let me see. I remember that VPLS uses SDPs to connect sites, and the FDB stores MAC addresses. I think the answer might be A, but I'm not 100% sure.

Hmm, I'm a bit unsure about this. I know VPLS has something to do with MAC learning, but I'm not sure about the specifics. I'll have to think this through carefully.

I'm pretty confident about this one. I think the answer is C - frames received on a SAP that are broadcast, multicast or unknown are flooded.

This seems like a straightforward data validation requirement. I'd probably go with option B, "required Fields", as that seems like the most direct way to ensure the customer provides either a phone number or email address.

Hmm, integration parameters? I'm not entirely sure what that means. Let me re-read the question and see if I can figure out the right approach.

Ah, I remember learning about SOAP in class. It's a standard for how web services communicate, so I'm confident A is the right answer.

Expert judgment makes the most sense to me. The other options don't seem directly relevant to validating the logic models. I'll go with A and move on to the next question.
