I’m a bit confused; I thought the underlay was just for transporting Layer 2 frames, which sounds like B. But I could be mixing it up with something else!

Based on my understanding, the purpose of the Cisco SD-Access underlay network is to provide virtualization by encapsulating network traffic over IP tunnels. That sounds like option D to me.

This seems straightforward. The user can see the reports but not execute them, so the administrator needs to configure the appropriate permissions, likely at the SQL database level, to allow the user to run the reports. I'll go with option C.
