300-415 · Question #27
Which two options are SD-WAN solution capabilities? (Choose two.)
The correct answer is B. The separation of management plane, control plane and data plane to enable horizontal scaling D. Cloud hosted or on-Premise fully redundant management and control plane functions. Key capabilities of an SD-WAN solution include the architectural separation of management, control, and data planes for horizontal scaling, and the flexibility to deploy management and control functions redundantly, either in the cloud or on-premises.

Why each option
Key capabilities of an SD-WAN solution include the architectural separation of management, control, and data planes for horizontal scaling, and the flexibility to deploy management and control functions redundantly, either in the cloud or on-premises.
While SD-WAN solutions often integrate security, the ability to integrate security with complementary products is a general IT capability and not a unique, defining architectural capability of SD-WAN itself.
A fundamental capability of SD-WAN, especially Cisco SD-WAN, is the separation of the management plane, control plane, and data plane. This architectural design enables centralized control, simplified operations, and independent, horizontal scaling of each network plane.
The concept of 'truck roll branch turn up' contradicts a primary benefit of SD-WAN, which is 'zero-touch provisioning' designed to minimize or eliminate the need for manual on-site intervention for new installations.
Cisco SD-WAN provides robust deployment flexibility and high availability for its management (vManage) and control (vSmart) plane functions. These critical components can be hosted either in a cloud environment or on-premises, with options for full redundancy to ensure continuous operation and meet diverse organizational infrastructure requirements.
