Cisco CCNA 200-301 Practice Question

Separating the control plane from the data plane allows for centralized network intelligence and management. This means network decisions and policies are made centrally by the controller, which improves scalability and simplifies network management. The data plane devices, like switches and routers, forward packets based on the controller's instructions but do not make decisions themselves. Reducing latency by processing data packets faster is not a direct result of this separation. Ensuring data security by encrypting all data traffic at the hardware level is unrelated to control and data plane separation. Enabling direct communication between hardware devices without a controller contradicts the concept of centralized control.
