CCIE Data Center (legacy) — Question 34

Which description of a hybrid SDN framework is true?

Answer options

• A. The data plane is pulled from the networking element and put in an SDN controller.
• B. The control plane is pulled from the networking element and put in an SDN controller.
• C. The control plane function is split between a SDN controller and the networking element.
• D. The control plane and data plane are pulled from the networking element and put in an SDN controller and SDN agent.

Correct answer: B

Explanation

The correct answer is B because a hybrid SDN framework involves moving the control plane from the networking element to the SDN controller, allowing for centralized management. Options A and D incorrectly refer to the data plane, which is typically not moved in a hybrid framework, while option C suggests a split control plane that does not accurately capture the essence of a hybrid approach.
