B is important too. Routing protocol is needed for CE communication.

I feel like A is crucial. MP-BGP is essential for customer routes.

I'm leaning towards D. Labels are exchanged with core devices, not CE.

But what about D? Isn’t MPLS essential for labels?

I’m not confident, but I think B could be the answer since it seems like a standard routing protocol setup.

I'm leaning towards D because I recall that MPLS is mainly for core devices, but I could be mixing it up with something else.

I think the answer might be C, but I'm not entirely sure. I remember something about label signaling protocols being used between PEs and CEs.
