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!

Haha, I bet the exam writers were feeling a bit 'guaranteed' when they came up with these answer choices!

Option D doesn't sound right. GR uses pre-calculated backup LSPs, not a new one for every failure.

I think option C is wrong. GR does require signaling of the fault to trigger the restoration process.

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

Actually, I think Hayley is right. B makes more sense because GR cannot guarantee 100% survivability in all scenarios.
