D definitely sounds like the correct answer. Forwarding decisions in a VPLS are all about those FDB lookups, like a well-choreographed dance between the PEs. It's like a networking version of the Macarena, but with less hip-shaking and more CLI commands.

I'm going with option D. The question mentions a full mesh and a spoke-SDP, so it's gotta be a VPLS setup. And if you ask me, the FDB lookup is the spice of life when it comes to these networking exams!

Hmm, I was a bit confused at first, but I think D is the way to go. Gotta love those VPLS FDB lookups, am I right? It's like a virtual maze, but with less Minotaurs and more Alcatel-Lucent equipment.

User 3: I always get a bit confused with all these configurations, but D does make sense in this scenario.

I think the correct answer is D. A VPLS FDB lookup is done at PE-A, PE-C, and PE-B to forward the traffic from PE-A to PE-D. The full mesh of mesh-SDPs and spoke-SDP configuration implies a VPLS setup, and the traffic would need to be looked up in the FDB at multiple PEs.
