ABR-1 needing T-LDP sessions to all ABRs in area 0 is definitely required.

Fast reroute on all RSVP-TE LSPs? I thought that was optional.

Wait, does it really need a full mesh of RSVP-TE LSPs? Sounds excessive.

I have a hunch that ABR-1 needing T-LDP sessions to all ABRs is not a requirement. It sounds familiar from my notes.

I practiced a similar question last week, and I remember that fast reroute is often necessary. Could it be option C instead?

I think option B might be the one that isn't required. I remember something about RSVP-TE not needing a full mesh in certain scenarios.

I'm not entirely sure, but I feel like T-LDP sessions are pretty crucial for the setup. Maybe option D is the answer?

This seems like a classic Expressway interoperability issue. I'm pretty confident I can identify the root cause by carefully examining the information provided in the question.

Hmm, I'm a bit unsure about the dBm to mW conversion. I'll need to review that concept before answering.
