Wait, does VPWS really emulate a Layer 2 connection?

VPWS is definitely point-to-point.

I vaguely recall something about encapsulation, but I’m not confident if VPWS encapsulates Layer 2 frames into IP datagrams. Maybe option D is the false one?

I practiced a similar question where VPWS was described as emulating Layer 2 connections, so I think option B is definitely true.

I’m not entirely sure, but I feel like VPWS does perform some kind of MAC learning, which might make option C the false one.

I remember studying that VPWS is indeed a point-to-point service, so I think option A is true.

Okay, I've got this. The costing sheet is assigned to the Costing variant, which is option D.

I remember we discussed something about TCP streams during our study group, but I'm not completely sure how enabling that feature works.

Option D looks promising - EnableJob seems like it could be the right method to enable a new job. But I'll double-check the parameter types to make sure that matches what the question is asking for.

Ugh, I don't remember much about how multicast is handled in the ACI fabric. I'll have to guess on this one and hope for the best.
