Show answer & explanation
Correct answer: B
The correct option is B. Software-Defined Networking (SDN) decouples the network's control plane from the data plane. The control plane acts as the centralized "brain," responsible for managing routing flow rules and making strategic decisions about how and where network traffic should be directed across infrastructure.
