Question 35

The controller is the core component of SDN and connects to devices through southbound interfaces. Which of the following are southbound protocols used by the controller? (Choose two.)

    Correct Answer: A, B

    The controller in Software-Defined Networking (SDN) communicates with network devices via southbound interfaces, and two commonly used southbound protocols are OpenFlow and NETCONF. OpenFlow is a standardized protocol that allows the controller to directly interact with the forwarding plane of network devices to manage traffic flow. NETCONF is a network management protocol that enables the controller to manage and configure network devices. Both protocols are well-established in the SDN architecture for establishing control and configuration channels between controllers and devices.
