A seems wrong, LSPs shouldn't need explicit config like that.

D is interesting too, but I think it's more about the path calculation.

Wait, so the head-end does all the work? Sounds a bit off.

I agree with B, makes the most sense.

It's definitely B! The head-end router calculates the initial path.

I thought a PCC-initiated LSP meant it had to be configured on the head-end router, but that doesn't seem to fit with what I studied about PCEs.

I feel like option D makes sense since it mentions the PCE, but I’m a bit confused about how it relates to the initiation of the LSP.

I remember practicing a question about LSPs and PCEs, and I think it was about how the PCE interacts with the LSP, but I can't recall the specifics.

I think a PCC-initiated LSP is one where the head-end router calculates the initial path, but I'm not entirely sure if that's the right answer.

I remember learning about PCC-initiated LSPs in class. Let me apply that knowledge to this scenario.

Okay, the key here is understanding the role of the PCE in the network. I'll focus on that to determine the correct answer.

Hmm, I'm a bit confused about the difference between PCC-initiated and head-end initiated LSPs. Let me think this through.

This question seems straightforward, I think I know the answer.

This question is a real head-scratcher. I think I'll go with option B since it sounds the most logical to me.

Hah, classic networking exam question. All these options sound like they could be right. I'm just going to guess and hope for the best!

D) An LSP whose existence and state are reported to the PCE.

B) An LSP for which the initial path is calculated by the head-end router.

A) An LSP that needs to be explicitly configured on the head-end router.
KE

I'm leaning towards option C. The head-end router should be responsible for triggering path repairs and re-optimizations.

I'm not sure, but I think option D is also a possibility. The PCE needs to be aware of the LSP's existence and state.
JO

I agree with you. Option B seems to be the correct choice.
DO

I think option B makes more sense. The head-end router calculates the initial path for the LSP.
VE

Option D seems like the correct answer. The PCE needs to know about the LSP's existence and state to be able to perform path computations.
AL

So, it's important for the PCC to report the LSP's status to the PCE for efficient network management.
ER
Erick

Yes, that makes sense. The PCE relies on that information to perform path computations.
SV

I think option D is correct. The PCE needs to be aware of the LSP's existence and state.

Hmm, that makes sense too. Maybe we should review the material again to be sure.
CE

I disagree, I believe it's an LSP for which the initial path is calculated by the head-end router.
