An organization wants to discover, monitor, and track the applications running on the WAN Edge device on the LAN. Which configuration achieves the goal?
A
An organization wants to discover, , -> this means app visibility
monitor -> visibility is needed to know what to minitor
"and track" -> even with no AAR, vManage keeps graphs for apps so you have tracking
What a hard question between A and D.
What do you think about: An organization wants to discover, monitor, "and track"
When you have dpi running on a Cisco Device, you can discover applications and flows passing through in real time:
show sdwan app-fwd dpi flows table
that's real time, so you are not tracking it I think, in the time after, flow disapears at one moment normally.
When you are configuring a netflow collector, you are saving those informations, so tracking more that only in real time? what do you think?
#show sdwan app-fwd dpi flows table
Generating output, this might take time, please wait ...

Enable Application Visibility on Cisco SD-WAN Devices
You can enable application visibility directly on Cisco SD-WAN devices, without configuring application-aware routing policy so that you can monitor all the applications running in all VPNs in the LAN. To do this, configure application visiblity on the router:
vEdge(config)# policy app-visibility
I would say "A". Enable Application Visibility on Cisco SD-WAN Devices
You can enable application visibility directly on Cisco SD-WAN devices, without configuring application-aware routing policy so that you can monitor all the applications running in all VPNs in the LAN. To do this, configure application visibility on the router:
vEdge(config)# policy app-visibility
https://www.cisco.com/c/en/us/td/docs/routers/sdwan/configuration/policies/vedge-20-x/policies-book/application-aware-routing.html
I think the answer is A:
"app-visibility
Enable application visibility so that a vEdge router can monitor and track the applications running on the LAN (on vEdge routers only)."
