Wait, are we really saying A is true? That seems off!

A is definitely false, LSPs use more than just routing tables.

I'm a bit confused about C; I thought constraint-based LSPs were calculated at the ingress, not at each hop.

I practiced a question similar to this, and I think D is definitely true since LDP is commonly used for IGP-based LSPs.

I feel like the constraint-based routed LSP is calculated at the ingress, but I can't recall the specifics about the router database.

I think I remember that IGP-based LSPs rely on routing tables, but I'm not sure if it's solely from them.

I'm not too confident about this one. I'll have to think it through step-by-step to make sure I understand which block of code is the correct solution.

Hmm, I'm a little unsure about the correct way to set up the event listeners here. I want to make sure I get this right, so I'll carefully read through the options and think it through step-by-step.

I'm pretty sure this is about how 'any willing provider' laws make it harder for health plans to control costs. I'm leaning towards option B about monitoring utilization.

I'm just glad they didn't ask about the secret handshake required to establish an LSP. That one always trips me up!

A and B for sure. As for C, that's just crazy talk. The network engineers must have been on a coffee break when they came up with that one.

Hmm, I thought IGP-based LSPs used RSVP signaling, not LDP. Maybe I need to review my MPLS notes again.

Yeah, IGP-based LSPs actually use RSVP signaling, not LDP. It's important to review the notes.

A and B seem to be the correct answers here. IGP-based LSPs are established using routing table information, and the constraint-based routed LSP is calculated at the ingress based on the router database and user constraints.
