200-301 Question 467
Select 3A company is transitioning from a traditional network to a controller-based networking approach to improve scalability and simplify management. Which of the following characteristics differentiate controller-based networking from traditional networks?
- A
Centralized control plane managed by a network controller
- B
Direct configuration of individual devices using CLI
- C
Simplified deployment of policies across the network
- D
Decoupling of the control plane from the data plane
- E
Device-specific configurations stored locally on each network device
Show answer and explanation
Correct answers: A, C, D
Explanation
Controller-based networking centralizes control and simplifies management by decoupling the control plane from the data plane. This approach allows network administrators to deploy policies across the network from a single controller, improving scalability and reducing the complexity associated with managing individual devices, which is a drawback of traditional networking.
- A. Correct.
Centralized control plane managed by a network controller is a key feature of controller-based networking, which allows for easier management and scalability.
- B. Incorrect.
Direct configuration of individual devices using CLI is a characteristic of traditional networks, not controller-based networking.
- C. Correct.
Simplified deployment of policies across the network is a major benefit of controller-based networking, as the controller can push configurations to all devices at once.
- D. Correct.
Decoupling of the control plane from the data plane is a hallmark of controller-based networking, enabling centralized decision-making and distributed forwarding.
- E. Incorrect.
Device-specific configurations stored locally on each network device is typical of traditional networks, where each device operates independently.
