I'm surprised R1 can also be a PLR.

Wait, can R3 really be a PLR if R2 fails?

All routers can be PLRs, that's true!

I think R4 becoming an MP is a bit off.

R1 is definitely the LSP head-end.

I feel like option C is misleading. R3 becoming a PLR if R2-R3 fails doesn't sound right to me.

I'm a bit confused about option B. If R1-R2 fails, does R4 really become an MP? I need to double-check that.

I remember a practice question where R1 was the head-end, so maybe option D is the right choice here?

I think option A might be correct since all routers can act as PLRs, but I'm not entirely sure.

I think the "1" might be indicating the version or revision number of the RP100-xx standard. That would make sense for the options provided. I'll go with B, "1 display", as my best guess.

Hmm, I'm not totally sure about this one. I know the Ishikawa diagram is used for root cause analysis, but I can't remember if that's specifically for risks or something else. I'll have to think this through.
