I'm a bit stumped on this one. Time to dust off my VPWS knowledge and give it another read-through.

Haha, the question mentions 'CEI' instead of 'PE1'. Looks like someone needs to proofread their exams more carefully!

I think C is false. PE1 and PE3 don't exchange service labels using A-D per EVI routes. That just doesn't make sense to me.

Hmm, this is tricky. I'm gonna go with D. The service labels are exchanged over a targeted LDP session between PE3 and PE4, not using A-D per EVI routes.

But what about option A? PEI advertising an auto-discovery route to PE3 doesn't seem right.

Option B seems to be the correct answer. PE3 would advertise an IMET route to PE1 as soon as VPWS 4 is enabled, not the other way around.

I disagree, I believe the false statement is D) PE3 and PE4 exchange their service labels over an established targeted LDP session.
