I’m confused about C. I thought service labels were exchanged through different methods, but I can’t recall the specifics.

I’m leaning towards D being false because I thought targeted LDP sessions were only for specific types of exchanges.

I feel like I’ve seen a similar question before, and it was about how PE routers advertise routes. Maybe B is the one that’s false?

I think A might be the false statement, but I'm not entirely sure. I remember something about auto-discovery being tied to operational status.

I'm not entirely sure about the details of VPWS 4 and how it interacts with EVPN. I'll need to think through the options carefully and try to eliminate the ones that don't seem plausible.

Okay, I think I've got this. The key is to identify the false statement about the operation of VPWS 4. I'll carefully evaluate each option and select the one that doesn't match the expected behavior.

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.
