C sounds right to me, one MP-BGP session for all EVIs makes sense.

I feel like the PE using a single MP-BGP session is a tricky one. It seems plausible, but I can't recall if that's always the case.

Ah, I remember this from the lecture. A PE definitely advertises locally-learned MAC addresses to remote PEs using EVPN type-2 routes, so D is the correct answer.

Okay, let me see. I know that PEs use a single MP-BGP session to exchange routes for all EVIs, so I think C is the false statement here.

This seems like a straightforward insurance-related question. I'll focus on understanding the key terms like "losses paid" and "outstanding loss reserves" to determine the correct answer.

Okay, let me see. Workspace ONE Access provides identity and access management, while Horizon is more focused on virtual desktops. I believe the correct answer is Workspace ONE UEM.
