200-301 Question 466
Select 3An organization is considering migrating from a traditional network to a controller-based networking model. The IT team is debating the benefits of this transition. Which of the following advantages are specific to a controller-based networking model compared to traditional networks?
- A
Centralized management of network policies and configurations
- B
Direct device-to-device communication without a central controller
- C
Enhanced automation through APIs and programmability
- D
Manual configuration of individual devices for policy changes
- E
Faster deployment of network changes across multiple devices
Show answer and explanation
Correct answers: A, C, E
Explanation
Controller-based networking introduces centralized management and automation, which are significant improvements over traditional networks. These features allow for streamlined policy enforcement, faster deployment of changes, and programmability through APIs, making the network more agile and easier to manage. In contrast, traditional networks rely on manual configurations and direct device-to-device interactions, which can be time-consuming and error-prone.
- A. Correct.
Centralized management is a core feature of controller-based networking, simplifying the management of large networks.
- B. Incorrect.
Direct device-to-device communication without a central controller is a characteristic of traditional networks, not controller-based networks.
- C. Correct.
Enhanced automation through APIs and programmability is a key feature in controller-based networks, enabling flexibility and ease of management.
- D. Incorrect.
Manual configuration of individual devices is typical in traditional networks and is minimized in controller-based networking.
- E. Correct.
Faster deployment of network changes is a benefit of controller-based networking due to centralized management and automation.
