Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 50

What is the function of SDN southbound API protocols?

Answer options

• A. to allow for the static configuration of control plane applications
• B. to enable the controller to use REST
• C. to enable the controller to make changes
• D. to allow for the dynamic configuration of control plane applications

Correct answer: C

Explanation

The correct answer is C because SDN southbound API protocols facilitate communication between the controller and network devices, allowing the controller to make real-time adjustments. Options A and D incorrectly describe static and dynamic configurations, which do not reflect the primary function of the southbound APIs. Option B is inaccurate as it misrepresents the REST usage, which is not the main purpose of these protocols.
