A is interesting, but I feel like it complicates things too much.

Wait, can SGTs really handle VN communication? Sounds off.

I think D is a solid choice too, route leaking works well.

E seems like the wrong answer. Shaping is definitely not just done in hardware and serviced in a round-robin. I think the key is to look for where traffic aggregation happens.

Hmm, I'm a bit unsure about this one. I know a single-homed AS is connected to only one other AS, but I'm not entirely clear on the other details. I'll need to think through each answer choice carefully.
