Haha, option A is probably true, but I'm picturing a PE router advertising its own MAC address on a MAC/IP route. That's just funny to imagine.

I think option A is true, each PE advertises a MAC/IP route with the MAC address of SBD IRB interface.

Hmm, I'm not sure about C. Isn't the VPRN service typically configured to advertise IP prefixes? That seems like a normal feature, not a false statement.

I agree, B doesn't sound right. The correct answer must be D - the SBD IRB interface has no IP address assigned to it in the interface-ful unnumbered forwarding model.
