I agree with Floyd. A) 100 makes sense for hierarchical VPLS.

I’m leaning towards D) 2. Just need one LSP per metro.

I feel like it's A) 100. Each service needs one LSP.

I’m confused about whether the LSPs are shared or dedicated. If they’re dedicated, then it could be 200, but if they’re shared, maybe just 2?

I practiced a similar question where we had to calculate LSPs for a different number of services. I think it was 2 LSPs for a pair of networks, but this one seems trickier.

I’m not entirely sure, but I feel like the number of LSPs could be related to the number of services. Maybe it’s 200 since each service might need its own LSP?

I think we might need to consider how VPLS services are structured. I remember something about needing multiple LSPs for redundancy.
