CCNA: Cisco Certified Network Associate — Question 308

What benefit does controller-based networking provide versus traditional networking?

Answer options

• A. allows configuration and monitoring of the network from one centralized point
• B. provides an added layer of security to protect from DDoS attacks
• C. combines control and data plane functionality on a single device to minimize latency
• D. moves from a two-tier to a three-tier network architecture to provide maximum redundancy

Correct answer: A

Explanation

The correct answer is A because controller-based networking centralizes the configuration and monitoring process, making it easier to manage the network. Options B, C, and D, while they may have their own advantages, do not specifically highlight the primary benefit of centralized management that controller-based systems provide.
