CCNA: Cisco Certified Network Associate — Question 310

In software-defined architectures, which plane is distributed and responsible for traffic forwarding?

Answer options

• A. management plane
• B. policy plane
• C. data plane
• D. control plane

Correct answer: C

Explanation

The data plane is the correct answer because it is specifically designed to forward user data packets. The management plane oversees configuration and management, the control plane makes routing decisions, and the policy plane enforces rules, but none of these are directly involved in the forwarding of traffic.
