SD-WAN can be used to provide secure connectivity to remote offices, branch offices, campus networks, data centers, and the cloud over any type of IP-based underlay transport network. Which two statements describe SD-WAN solutions? (Choose two.)
A.
Control and data forwarding planes are kept separate.
B.
Solutions allow for variations of commodity and specialized switching hardware.
C.
SD-WAN networks are inherently protected against slow performance.
D.
Solutions include centralized orchestration, control, and zero-touch provisioning.
E.
Improved operational efficiencies result in cost savings.
I think correct ans are A and D
A. Control and data forwarding planes are kept separate: In the SD-WAN architecture, the control and data forwarding planes are kept separate to centralize management and policy enforcement across the network and to streamline data forwarding. This separation allows for flexible management and rapid deployment. This separation allows for flexible management and rapid network changes.
D. Solutions include centralized orchestration, control, and zero-touch provisioning. SD-WAN solutions feature centralized orchestration and control, simplifying configuration and management of the entire network. Zero-touch provisioning also enables rapid deployment of new devices, improving operational efficiency. This allows administrators to easily manage complex networks.
separates the control plane and data forwarding plane is more of a design principle. Cost savings is the best answer and why we choosing SD-WAN over traditional solutions.
SD-WAN is a form of SDN, separate control/forwarding planes.
SD-WAN uses Orchestration and ZTP. Both of these are true.
Now look at the choice of E regarding cost savings. SD-WAN does enable cost savings, but not due to operational efficiencies. Instead these costs savings are from enabling the use of commodity circuits such as broadband over the use of expensive MPLS circuits. Operational efficiencies provides many technical benefits, but cost savings is questionable.
So A & D for me.
Answer is: AE
An SD-WAN uses a "centralized control function to securely and intelligently route traffic across the WAN". This enhances application performance and provides a high quality user experience, resulting in increased business productivity, agility and "lessened costs" for IT.

I'd agree with DE also. https://blogs.cisco.com/sp/the-rise-of-cisco-sd-wan
