An enterprise is transitioning from a traditional distributed network architecture to a controller-based software-defined networking (SDN) model. Which two statements describe key operational characteristics of a controller-based networking approach? (Select two.)
- Control plane intelligence is centralized on a software controller rather than executing independently on each individual device.Cevap
- BData plane packet processing is relocated entirely to the SDN controller, eliminating hardware forwarding mechanisms on network switches.
- Network policies and configurations are programmatically deployed across the fabric via centralized management interfaces and APIs.Cevap
- DSouthbound APIs serve as the primary interface for network engineers to write management scripts and interact with the controller dashboard.
Cevap
Control plane intelligence is centralized on a software controller rather than executing independently on each individual device, and network policies and configurations are programmatically deployed across the fabric via centralized management interfaces and APIs.
Controller-based networking centralizes control plane intelligence into a software controller rather than running isolated control plane protocols on every individual network node. Additionally, network provisioning is executed programmatically through centralized management platforms and APIs rather than individual CLI connections.
