I remember that 'max-sr-frr-labels' is a parameter, but I can't quite remember if it specifically limits R-LFA labels or something else.

I practiced a similar question where we discussed the role of fast re-route in segment routing, and I feel like option D could be misleading.

I'm not entirely sure about option C; I remember something about R-LFA and TI-LFA being related, but I can't recall if they can be enabled independently.

I think option A sounds correct because fast re-route is indeed meant to be a temporary solution during failures.

The 'max-sr-frr-labels' parameter sounds familiar, but I can't quite recall what it does. I'll have to think this through carefully.

Wait, what's the difference between protecting the active segment versus the entire multi-segment tunnel? I'm a bit confused on that part.

Ah, I've worked with R-LFA and TI-LFA before. I'm pretty confident I know the difference between them, so this should be straightforward.

Ah, this is a tricky one. I'm leaning towards gap analysis, but I want to double-check the definitions of the other options just to be sure.
