Final answer:
The application plane is not centralized on an SDN network.
Step-by-step explanation:
The statement is False. The application plane is not centralized on an SDN network. In Software-Defined Networking (SDN), the control plane is centralized, meaning that network control is separated from the forwarding plane of network devices. The control plane is responsible for managing and configuring the network, while the forwarding plane handles the actual forwarding of packets. The application plane, on the other hand, refers to the layer where applications and services are run, and it is not centralized in an SDN network.
