Answers

D.

Only controller-based networks decouple the control plane and the data plane

Answers
D.

Only controller-based networks decouple the control plane and the data plane

Suggested answer: D

Explanation:

Most traditional devices use a distributed architecture, in which each control plane is resided in a networking device. Therefore they need to communicate with each other via messages to work correctly.

In contrast to distributed architecture, centralized (or controller-based) architectures centralizes the control of networking devices into one device, called SDN controller
