Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 474

In a Cisco Software Defined Networking (SDN) architecture, what is used to describe the API communication between the SDN controller and the network elements (routers and switches) that it manages?

Answer options

• A. Southbound API
• B. Northbound API
• C. Westbound API
• D. Eastbound API.

Correct answer: A

Explanation

The correct answer is A, Southbound API, as it specifically refers to the communication interface used by the SDN controller to interact with the network elements. The other options, Northbound, Westbound, and Eastbound APIs, do not describe the communication with network devices but rather serve different purposes in the SDN architecture.
