The technology that separates the control plane and forwarding plane is SDN.
The correct answer is A. TRUE. A (TRUE) is correct because Software-Defined Networking (SDN) is defined by its architectural separation of the control plane (the "brain" that decides how traffic should flow) from the forwarding/data plane (the "muscle" that actually moves packets).

Explanation
A (TRUE) is correct because Software-Defined Networking (SDN) is defined by its architectural separation of the control plane (the "brain" that decides how traffic should flow) from the forwarding/data plane (the "muscle" that actually moves packets). In traditional networking, both functions are tightly coupled within the same hardware device (e.g., a router). SDN decouples them by centralizing control logic in a software-based SDN controller, while forwarding hardware simply executes instructions it receives.
There are no real distractors here since it's a true/false question - B (FALSE) is wrong because the control/forwarding plane separation is not just a feature of SDN, it is its core defining characteristic.
Memory tip: Think of SDN like a GPS and a driver - the GPS (control plane) decides the route, and the driver (forwarding plane) just follows instructions. SDN = Separated Decisions from Network hardware.
