Definitely 200, each service needs an LSP in both metros.

I thought it would be less, like 100 or something.

Totally agree, 200 makes sense for 100 services.

If I recall correctly, hierarchical VPLS can optimize LSP usage, but I still think we need at least one LSP for each service. So, maybe 100?

I’m a bit confused about how the hierarchical aspect affects the LSP count. Does it mean we need fewer LSPs overall?

This question feels similar to one we practiced about LSPs and VPLS. I think we discussed needing double the number of services for two metros, so maybe it's 200?

I think I remember that each VPLS service might require its own LSP, but I'm not entirely sure if they can share them.

This seems like a pretty standard VPLS question. I'll just need to apply the basic VPLS concepts and do the math to arrive at the correct answer. I'm feeling confident about this one.

I'm a little confused by the wording of the question. Is it asking for the total number of LSPs required, or just the number of LSPs between the two metro networks? I'll need to think this through carefully.

Okay, let's see. Each VPLS service requires two LSPs, one in each direction. With 100 VPLS services across two metro networks, that should be 200 LSPs in total. I'll go with option B.

Hmm, I'm a bit unsure about this one. I'll need to review my VPLS concepts and do some quick calculations to determine the total number of LSPs.

This looks like a straightforward VPLS question. I'll need to think through the number of LSPs required for 100 hierarchical VPLS services across two metro networks.

Ah, the age-old question of how many LSPs are required for VPLS services. I'm going to go with B) 200, because that's the answer that sounds the most like a made-up number. Hey, at least I'm being honest, right?

Alright, time to put on my thinking cap. 100 services, huh? Okay, I'm feeling lucky, let's go with D) 2. Because two is always better than one, am I right?

This is a trick question, I just know it. I'm going to go with the least obvious answer, C) 1. Who needs 200 LSPs for 100 services? That's just overkill.

User 1: I think the answer is B) 200. Each service needs 2 LSPs, so for 100 services, it would be 200 LSPs in total.

Wait, what? 100 services, but only 1 or 2 LSPs? That can't be right. I'm going with B) 200. Gotta have one LSP per service, right?
