I heard GR can achieve 100% survivability, but I'm not so sure about that.

Definitely agree, GR calculates new backup LSPs for each failure.

Wait, GR doesn't need to signal faults? That sounds off.

I think GR can do more than just 100% survivability for single failures.

GR does use reestablished backup LSPs, that's a fact.

I practiced a question similar to this, and I think GR calculates new backup LSPs, but I can't remember if that's every time or just under certain conditions.

I feel like GR doesn't need to signal faults for restoration, but that seems a bit too straightforward.

I remember something about GR and survivability, but I can't recall if it really only applies to single failures.

I think GR is about using backup LSPs, but I'm not sure if they are always reestablished or just reserved.

I feel pretty good about this one. The description of GR using pre-established backup LSPs with reserved resources sounds right to me. I'll go with that.

Okay, I've got a strategy for this. I'll eliminate the options that don't sound right, then focus in on the key details about GR to determine the correct answer.

Hmm, I'm a bit unsure about this one. The options are pretty technical and I'm not totally confident in my GMPLS knowledge. I'll have to think it through step-by-step.

This question seems to be testing our understanding of guaranteed restoration in GMPLS. I'll need to carefully read through the options and think about the key characteristics of GR.

Wait, is GR the one where you get a free backup LSP if the first one doesn't work? Sounds like a sweet deal to me!

Option A seems to be the correct answer. Guaranteed restoration uses pre-established backup LSPs with resources reserved and configured.

So, GR doesn't calculate a new backup LSP every time a failure occurs. It's all pre-configured.
