I thought NSF would keep things stable, but guess not!

I think the answer is A. RC will cause all to tear down.

I believe that if RA goes down, RC will definitely affect the peering, but I’m torn between options A and D. I need to think this through more.

I’m a bit confused about the specifics of NSF. I thought that if one router doesn’t support it, the others might still hold their sessions, but I can't recall clearly.

I practiced a similar question where the behavior of routers during a switchover was tested. I’m not entirely sure, but I feel like option A could be correct.

I think I remember that when NSF is involved, it helps maintain peer relationships, but since RC doesn't support it, things might get tricky.

I'm leaning towards the hunt pilot option. It seems like the right place to manage those numbers.

Sending the same message to everyone feels like the wrong choice; we definitely talked about that in class.

Hmm, this seems tricky. I'm a bit confused about how the number of methods created would differ between the two options. I'll need to think this through step-by-step.

I remember a question about whether written reports need to be distributed to governance. I think it was something like this, but I can't recall the specifics.
