Nichel Jhon 2021-08-18

This CCNA training is considered associate-level Cisco training, which means it was designed for junior network administrators. This 200-301 CCNA course is valuable for new IT professionals with at least a year of experience with networks and experienced network administrators looking to validate their Cisco skills.

378. Which statement correctly compares traditional networks and controller-based networks?

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

B.Traditional and controller-based networks abstract policies from device configurations.

C. Only traditional networks natively support centralized management.

D. Only traditional networks offer a centralized control plane.

Answer:A

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.
