Question 33/132
SDN requires the control and forwarding planes to be separated.
Correct Answer: A
Comprehensive Explanation: In Software-Defined Networking (SDN), the control plane (which makes decisions about where to send traffic) is separated from the forwarding plane (which actually moves packets to their destinations). This separation allows for centralized control and management of the network, enabling programmability and greater flexibility. SDN controllers manage the control plane, while individual switches or routers handle the forwarding of data.
