350-401 Exam Dumps - Cisco CCNP Enterprise Questions and Answers

The correct answer is A. interface between the controller and the network devices.

In Cisco controller-based architectures such as Cisco DNA Center / Cisco Catalyst Center, APIs are generally described in two directions:

Northbound APIs → used by external applications, users, or orchestration systems to communicate with the controller

Southbound APIs → used by the controller to communicate with the network devices

A southbound API provides the communication path between the controller and the infrastructure devices such as switches, routers, and wireless devices. This is how the controller pushes configuration, collects operational data, and manages the network.

B. interface between the controller and the consumer This describes a northbound API, not a southbound API.

C. NETCONF API interface for orchestrator communication Orchestrator communication is generally associated with northbound integration, not the fundamental definition of Cisco DNA southbound APIs.

D. RESTful API interface for orchestrator communication This also describes northbound API behavior, where external systems communicate with the controller.

Remember this controller model clearly:

Northbound API = controller ↔ applications / orchestration / users

Southbound API = controller ↔ network devices

Southbound = toward the infrastructure
