CCNA: Cisco Certified Network Associate — Question 514

What is a function of a southbound API?

Answer options

• A. Use orchestration to provision a virtual server configuration from a web server
• B. Automate configuration changes between a server and a switching fabric
• C. Manage flow control between an SDN controller and a switching fabric
• D. Facilitate the information exchange between an SDN controller and application

Correct answer: C

Explanation

The correct answer is C because a southbound API is specifically designed to manage communication and flow control between the SDN controller and the network elements like switching fabrics. Options A, B, and D do not accurately describe the primary function of a southbound API, as they relate to different aspects of network management and orchestration.
