Not sure about that, I thought all setups needed some loop prevention.

I think option B is also important for ring networks.

Wait, does that mean we can skip RSTP? Sounds too good to be true.

A key benefit is that the MDU doesn't need to support MPLS.

I recall that ring networks can be complex, so option B might be a benefit, but I can't remember the details about how that works with pseudowires.

I practiced a similar question about MPLS benefits, and I feel like option A could be a trick answer since MPLS is usually important for pseudowires.

I'm not entirely sure, but I remember something about how pseudowires can simplify network configurations. Maybe option C is relevant?

I think option D might be correct because it seems like the MDU shouldn't need to know about the active/standby setup.
