Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 436

What are two functionalities of SDN southbound APIs? (Choose two.)

Answer options

• A. Southbound APIs from the interface between the SDN controller and business applications.
• B. Application layer programs communicate with the SDN controller through the southbound APIs.
• C. OpenFlow is a standardized southbound API protocol used between the SDN controller and the switch.
• D. Southbound APIs form the interface between the SDN controller and the network switches and routers.
• E. Southbound APIs provide a programmable interface for applications to configure the network.

Correct answer: C, D

Explanation

The correct answers are C and D because OpenFlow is indeed a standardized protocol that facilitates communication between the SDN controller and network devices like switches, and southbound APIs specifically connect the SDN controller to network switches and routers. Options A, B, and E describe aspects of SDN but do not accurately represent the primary functions of southbound APIs.
