- Cisco DNA Center (Catalyst Center) acts as a centralized controller, replacing device-by-device CLI management with automation.

- Intent-based networking allows you to define business outcomes (the 'what'), which DNA Center then translates into network configurations (the 'how').

- The underlay is the physical network providing basic connectivity, while the overlay is the virtual network (using VXLAN) that enforces policy in SD-Access.

- DNA Center Assurance provides analytics and AI-driven insights to proactively monitor network health and accelerate troubleshooting.

- Northbound APIs are used for integration, allowing external IT systems to programmatically interact with the network via DNA Center.
