Three advantages of controller-based networks versus traditional networks are:
-
Allows for mass configuration - Controller-based networks enable administrators to configure multiple devices simultaneously from a central point, which saves time and effort compared to configuring each device individually.
-
Can monitor the entire network connected to the controller - A centralized controller can provide an overview and real-time monitoring of the entire network, allowing for easier troubleshooting and performance assessment.
-
Central management - Controller-based architectures allow for centralized management of network resources, policies, and settings, which enhances efficiency and consistency across the network.
The option "Each device is independent of each other" does not accurately reflect an advantage of controller-based networks, as they typically promote coordinated operation among devices rather than independence.
