Which of the following statements is true with regard to SDN?
- It combines the control plane and the data plane
- It separates the data plane and the forwarding plan
- It implements the control plane as software
- It implements the data plane as software
In Software-defined networking (SDN), the control plane is separated from the data (or forwarding) plane and is implemented through software. The data plane remains on each physical device but the control plane is managed centrally for all devices though software.
SDN does not combine the data and control plane. Instead it decouples them.
SDN does not separate the data plane and the forwarding plan. These are both names for the same plane; that is, a data plane is a forwarding plane.
SDN does not implement the data plane as software. The data plane remains on each physical device.
