I feel like C is less likely. Router 1 should initiate the tunnel.

Option B is important too. RSVP bandwidth must match on both ends.

Definitely D. Without it, the tunnel won't even start.

I agree, but what about option A? An explicit path might be necessary too.
RO

I think option D is crucial. MPLS TE needs to be enabled on the interface.

I thought it was A at first, but D makes more sense now.

B seems important too, can't overlook the RSVP bandwidth!
DA

I think D is the right answer. MPLS TE needs to be enabled on the interface.

I definitely recall that MPLS TE needs to be enabled on the interface, so option D could be the correct answer.

I’m a bit confused about option C; I thought the tunnel interface was only needed on the originating router, not the destination.

I remember something about RSVP bandwidth from practice questions, so option B might be the right choice.

I think option A sounds familiar, but I'm not entirely sure if it's necessary to define an explicit path.
