Which term is an open-source variant of software defined networking?

• A. Data Plane/Forwarding Plane
• B. Management Plane
• C. Open SDN
• D. Orchestration

Answer: (C)

Open SDN embodies an open-source approach within software-defined networking, where the software, standards, and implementations are freely available and community-driven. This openness enables interoperability and collaboration across vendors and projects, which is what “open-source variant” refers to in the SDN space. The other options describe parts or concepts of SDN rather than an open, community-led variant: the data/forwarding plane is the path packets take through the network; the management plane covers configuration and policy; and orchestration is about coordinating resources and services. So, Open SDN is the term that best fits “an open-source variant of software defined networking.”
