Question

A network automation team is building a custom dashboard application that pulls device health and network assurance data from Cisco Catalyst Center. The application communicates with Catalyst Center over a RESTful interface, while Catalyst Center itself uses device-facing protocols to push configuration to the switches and routers it manages. Which statement correctly characterizes the API relationship in this SDN architecture?

Accepted Answer

The dashboard application uses a Northbound API to communicate with the Catalyst Center controller, and Catalyst Center uses Southbound protocols to communicate with the network devices.

Answer

The dashboard application uses a Southbound API to communicate with the Catalyst Center controller, and Catalyst Center uses Northbound protocols to communicate with the network devices.

Answer

Both the dashboard application and the network devices communicate with Catalyst Center exclusively through Northbound APIs.

Answer

The dashboard application communicates with the network devices directly using a Westbound API that bypasses the controller.
