200-901 Question 141
Select 3A network engineer is tasked with managing a large-scale enterprise network. The engineer is debating whether to use a controller-level management approach or a device-level management approach. Which of the following features are specific to controller-level management?
- A
Centralized management of multiple network devices through a single interface
- B
Configuration changes made directly on individual devices
- C
Network-wide policy enforcement and automation
- D
Limited scalability when managing a large number of devices
- E
Real-time monitoring and telemetry across multiple devices
Show answer and explanation
Correct answers: A, C, E
Explanation
Controller-level management provides centralized control, enabling network-wide policy enforcement, automation, and real-time monitoring across devices. This approach contrasts with device-level management, which requires manual configuration and lacks the scalability and efficiency needed for large networks.
- A. Correct.
Centralized management of multiple network devices through a single interface is a key characteristic of controller-level management, as it enables administrators to manage the entire network from a central point.
- B. Incorrect.
Configuration changes made directly on individual devices is specific to device-level management, not controller-level management.
- C. Correct.
Network-wide policy enforcement and automation are significant advantages of controller-level management, enabling consistency and reducing manual effort.
- D. Incorrect.
Limited scalability is a drawback of device-level management, whereas controller-level management is designed to handle scalability for large networks.
- E. Correct.
Real-time monitoring and telemetry across multiple devices is a feature of controller-level management, providing centralized visibility and insights.
