Answer:
D
Explanation
The Open Networking Foundation identifies three main parts
of the Software-defined
networking (SDN): Application layer; Control layer and Infrastructure layer. SDN separates a
router’s control plane from the data (forwarding) plane. The control plane makes routing
decisions. The data plane forwards data (packets) through the router. With
SDN routing,
decisions are made remotely instead of on each individual router.
