What are two advantages of controller-based networks versus traditional networks? (Choose two.)

The correct answer is A. more consistent device configuration D. the ability to configure the features for the network rather than per device. Controller-based networks centralize management so configurations are applied uniformly and policies are defined at the network level rather than device by device.

Why each option

Controller-based networks centralize management so configurations are applied uniformly and policies are defined at the network level rather than device by device.

Amore consistent device configurationCorrect

A controller pushes configurations from a single centralized point, eliminating per-device inconsistencies that arise from manual CLI management across distributed devices.

Bthe ability to have forwarding tables at each device

Forwarding tables at each device describe the distributed forwarding model of traditional networks, not an advantage unique to controller-based architectures.

Cprogrammatic APIs that are available per device

Per-device programmatic APIs exist in traditional networks as well and do not represent a distinguishing advantage of controller-based networks.

Dthe ability to configure the features for the network rather than per deviceCorrect

Controller-based architectures allow administrators to define intent and policy at the network level, and the controller translates that policy into device-specific configuration, removing the need to configure each device individually.

Emore flexible configuration per device

Flexible per-device configuration is a characteristic of traditional networks where each device is managed independently, which is the opposite of what controller-based networks aim to achieve.
