A is definitely wrong, VPLS needs an FDB to function properly.

D seems right, separate FDBs for each service is logical.

Wait, are there really two FDBs for each service? That sounds complicated!

C makes more sense, it should track all VPLS services.

I think B is correct, FDBs track MACs on the PE router.

I vaguely remember that there could be multiple FDBs, but I’m not sure if it's two for each service or just one. I need to think about the multicast and broadcast traffic part.

I’m a bit confused about whether there’s one FDB for all services or separate ones. I thought each VPLS might have its own FDB, but I can't recall clearly.

I practiced a question similar to this, and I feel like option C sounds right since it mentions tracking MAC addresses for all VPLS services on the router.

I think I remember that an FDB is related to how MAC addresses are learned, but I'm not sure if it's for all traffic or just specific services.

Ah, this is a tricky one. I'm torn between B and D. I know the FDB is used to track MAC addresses, but I'm not sure if it's for all traffic or just the VPLS services. I'll have to think this through carefully.

I'm pretty confident that the correct answer is C. The FDB on the PE router tracks MAC addresses learned from all VPLS services configured on that router, not just a single service.

Hmm, I'm a bit unsure about this one. I know VPLS is a Layer 2 VPN service, but I'm not totally clear on the specifics of how the FDB works in that context. I'll have to review my notes to see if I can figure this out.

This question seems to be testing my understanding of how VPLS services use forwarding databases (FDBs). I'll need to think carefully about the different options and how they relate to VPLS.

Okay, I think I've got this. For a VPLS service, a separate FDB is maintained for each VPLS instance on the PE router to track the MAC addresses learned from that specific service. That sounds like option D to me.

Hmm, I'm a bit unsure about this one. "Cost-benefit thinking" could apply to a few different areas of financial management. I'll need to re-read the question and options closely to determine the best answer.

Assigning ownership seems like a good step, but I'm not sure if that alone would be the best way to enable an effective information asset classification process.

Haha, I'll go with D. Gotta keep those MAC addresses on a tight leash, one FDB per VPLS service. Anything else would be like trying to herd cats, am I right?

Option D all the way! It's the only one that specifically mentions 'a separate FDB' for each VPLS service. The others don't seem to capture the nuance of how the FDB is handled in a VPLS setup.
