Which two actions must be taken to allow certain department to require firewall protection when interacting with data center networks without including other departments? (Choose two.)

Using classification, policing, and marking are QoS mechanisms that control traffic flow and priority, but they do not directly enable or provision a firewall service for specific departments.

The firewall service must be advertised to vSmart controllers so that the vSmart controllers can build a topology that includes the firewall service and inform the relevant vEdge routers about its availability for service chaining. This allows the vSmart to intelligently direct traffic through the firewall.

While a regional hub might host the firewall, simply stating "The regional hub advertises the availability of the firewall service" is not precise enough; it is the vSmart that learns of the service from the devices providing it.

Applying data policies at vEdge is a mechanism to enforce traffic flow, but it does not describe the prerequisite steps of deploying the service and making it known to the control plane, which are covered by B and E.
