In an SD-Access deployment, what primary role does Cisco DNA Center perform?

Cisco DNA Center is the centralized management and automation platform for SD-Access. Its primary role encompasses the entire lifecycle of the fabric network, including designing the network topology, managing device configurations, deploying new devices, provisioning services and policies, and providing assurance through monitoring and troubleshooting. This comprehensive control makes it the single pane of glass for SD-Access operations. The other options are incorrect because: Routing decisions inside the fabric are handled by the control plane nodes (e.g., LISP Map-Servers and Map-Resolvers) and data plane devices (e.g., fabric edge nodes, fabric border nodes). While DNA Center can integrate with external systems, its primary role is not solely focused on non-fabric nodes and their counterparts; it manages the fabric itself. While DNA Center collects information about endpoints and network devices for assurance and policy enforcement, it doesn't solely "possess" this information as its primary role; rather, it uses this information to perform its management and automation functions.
