Ah, I see what you mean. This is a classic 'which one doesn't belong' type of question. I'll go with B as well.

Yeah, I agree. B doesn't seem necessary to protect the tunnel.

I agree with Kirk, D makes sense because fast reroute would help protect the tunnel.

Wait, isn't the correct answer supposed to be the one that's 'NOT required'? I'm going with B then.

Haha, this question is a bit tricky. I'd go with C. ABR-1 needs to have T-LDP sessions to all the ABRs in area 0.

I see your point, but I still think it's C. ABR-1 requires T-LDP sessions to all ABRs in area 0.

No, I disagree. It's actually D. PE-1 needs fast reroute enabled on all RSVP-TE LSPs.

I think it's B. PE-1 needs a full mesh of RSVP-TE LSPs to all routers in area 1.

Hmm, I'm not so sure. Isn't fast reroute on the RSVP-TE LSPs important for redundancy? I'm leaning towards D.

I think the answer is B. A full mesh of RSVP-TE LSPs is not required to protect the LDP-over-RSVP tunnel.
