CCNA: Cisco Certified Network Associate — Question 1170

What is the difference between controller-based networks and traditional networks as they relate to control-plane and/or data-plane functions?

Answer options

• A. Controller-based networks centralize all important data-plane functions, and traditional networks distribute data-plane functions.
• B. Traditional networks centralize all important control-plane functions, and controller-based networks distribute control-plane functions.
• C. Traditional networks centralize all important data-plane functions, and controller-based networks distribute data-plane functions.
• D. Controller-based networks centralize all important control-plane functions, and traditional networks distribute control-plane functions.

Correct answer: D

Explanation

The correct answer is D because controller-based networks centralize control-plane functions, allowing for more efficient management and orchestration of network resources. In contrast, traditional networks often distribute these functions, which can lead to less efficient operations and management challenges. Options A, B, and C incorrectly describe the distribution and centralization of data-plane and control-plane functions.
