CCNA: Cisco Certified Network Associate — Question 53

Which statement compares traditional networks and controller-based networks?

Answer options

• 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.

Correct answer: A

Explanation

The correct answer A is accurate because controller-based networks are specifically designed to decouple the control plane from the data plane, which is not a feature of traditional networks. Option B is incorrect as traditional networks do not inherently abstract policies. Option C is misleading since controller-based networks also support centralized management. Option D is false because controller-based networks provide a centralized control plane, unlike traditional networks.
