   A network architect is designing an SDN solution and needs to ensure that the controller can communicate with both OpenFlow-enabled switches and legacy devices that only support SNMP. The architect wants to use a single controller to manage both types of devices. What should the architect implement?

   • AA separate controller for each device type
   • BA northbound API for each device type
   • CA southbound abstraction layer that supports multiple protocols
   • DA proprietary protocol for all devices
