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.
SD-WAN networks are inherently protected against slow performance.
B.
Control and data forwarding planes are kept separate.
C.
Improved operational efficiencies result in cost savings.
D.
Solutions include centralized orchestration, control, and zero-touch provisioning.
E.
Solutions allow for variations of commodity and specialized switching hardware.
C: Centralized policy, simplified management, and dynamic path selection improve operational efficiency, directly resulting in cost savings.
D: SD-WAN provides centralized orchestration, automation, and zero-touch provisioning, simplifying deployment and scaling.
Why other options are incorrect:
A: SD-WAN improves performance with features like dynamic path selection but cannot inherently prevent slow underlay performance.
B: Many SD-WAN solutions logically separate control and data planes, but not all strictly follow full separation like traditional SDN.
E: SD-WAN is typically hardware-agnostic but does not depend on specialized switching hardware.
