I disagree with Elza, because the VPRN service should indeed allow the advertisement of IP prefixes for Layer-3 EVPN service.

Ah, the joys of networking exams. Where we get to play 'Spot the Odd One Out' with obscure protocol configurations. At least it's not as bad as studying for the 'MPLS for Penguins' certification.

Option C is the false one. The VPRN service should be configured to allow the advertisement of IP prefixes, not the other way around.

This question is making my brain hurt. Why do we need to remember all these technical details about EVPN forwarding models? I just want to pass the exam and get it over with.

I think Option D is the correct answer. The SBD IRB interface in the VPRN service should not have an IP address assigned to it, as per the unnumbered forwarding model.
