Drag and drop the elements from the left onto the functions they perform in the Cisco SD-WAN architecture on the right.

Refer to the exhibit. A network engineer is designing an OSPF solution to connect a company's remote to a newly provisioned MPLS VPN backbone. Some of the branches have a direct dark fiber connection between each other. The engineer wants to ensure that the dark fibers are used only when the MPLS core is unavailable.
Which solution must the engineer choose?

An engineer must propose a solution for a campus network that includes the capability to create multiple Layer
3 virtual networks. Each network must have its own addressing structure and routing table for data forwarding.
The solution must be scalable to support hundreds of virtual networks and allow simple configuration and management with minimal administrative overhead. Which solution does the engineer recommend?
