The physical separation of the network control plane from the forwarding plane, and where a control plane controls several devices.

• A. Software-Defined Networking (SDN)
• B. Control Plane
• C. Data Sensitivity Levels
• D. Peering

Answer: (A)

Software-Defined Networking embodies the separation of the control plane from the forwarding (data) plane, with a centralized controller managing multiple devices. In SDN, the control logic lives in a software controller that decides how traffic should be forwarded and then programs the forwarding devices accordingly. The switches or routers themselves simply execute the instructions they receive, rather than making independent routing decisions. This centralized approach contrasts with traditional networks where each device carries both the control and forwarding functions. Other terms like the Control Plane alone describe decision-making, but don’t capture the cross-device centralization; Data Sensitivity Levels and Peering relate to data handling and interconnection, not the control/forwarding separation.
