D is definitely false, it’s more complex than that.

Wait, all labels popped? That seems too simple!

C seems off, not sure about that one.

I think B is correct, sounds right to me.

PE1 definitely pushes three labels.

Charlette 1 year ago

I have a feeling that option D is the false statement because PE2 usually does more than just pop all labels before forwarding.

I practiced a similar question where PE routers pushed multiple labels, so I feel like option A could be true, but I’m not entirely confident.

I remember that in the VPRN model, PE routers handle the labels, but I'm not sure if ASBRs pop or swap labels in this scenario.

I think option C sounds familiar, but I can't recall if ASBR2 actually pushes an LDP label or if it just swaps the BGP label.

Hmm, I'm not sure about this one. Out of Office could be useful to see who's available, but I'm not sure if that really solves the problem of gathering feedback. I'll have to think this through a bit more.

I think I know this one. The pre-delivered MM standard data model in SAP Master Data Governance for Material covers Sales, Customer, and Plant data.

I'm a little confused by the different audit program options mentioned. I'll need to re-read that part carefully to make sure I'm understanding the context correctly before answering.

Okay, I've got an idea. Option D looks promising - running custom keyword scans on outbound email traffic could help identify and block any "Company Proprietary" files being sent out. That seems like a good way to enforce the new policy.
