I'm leaning towards A, but I can't recall if the head-end router's address is always used for RESV messages.

I remember practicing a similar question, and I think it was about how the router determines the next hop. Maybe it's D?

I feel like I studied this, and it could be C, but I get confused between PSB and RRO sometimes.

Hmm, this one's tricky. I'm not sure if POTS, ISDN, and T1 lines are actually examples of message switching. I'll have to think this through carefully.

I'm not sure, but I think it might be D) It sets the address to the next upstream hop from the RRO, as the Record Route Object keeps track of the path taken by the message.
