200-301 Question 468
Select 4An organization is considering migrating from a traditional network to a controller-based networking approach. Which of the following benefits are specific to a controller-based network compared to a traditional network?
- A
Centralized management of network policies and configurations
- B
Automation of repetitive network tasks, such as provisioning and updates
- C
Direct device-to-device communication without intermediary systems
- D
Improved scalability by abstracting the control plane from individual devices
- E
Reduced reliance on hardware by leveraging software-defined principles
Show answer and explanation
Correct answers: A, B, D, E
Explanation
Controller-based networking provides significant advantages over traditional networks, such as centralized management, automation, scalability, and reduced reliance on hardware. These features streamline network operations and improve efficiency, whereas traditional networks rely more on device-specific configurations and manual management.
- A. Correct.
Centralized management of network policies and configurations is a hallmark of controller-based networking, enabling administrators to manage the network from a single point.
- B. Correct.
Automation of repetitive tasks is a key benefit of controller-based networking, as controllers can push configurations and updates to multiple devices simultaneously.
- C. Incorrect.
Direct device-to-device communication is a feature of traditional networks, where devices often communicate directly without a centralized controller.
- D. Correct.
Improved scalability is inherent to controller-based networking because separating the control plane from individual devices allows for more flexible and efficient scaling.
- E. Correct.
Reduced reliance on hardware is a benefit of controller-based networking, as software-defined principles take precedence over hardware-centric configurations.
