What are two examples of components that are part of an SDN architecture? (Choose two.)
The correct answer is B. application plane E. control plane. SDN architecture defines three primary planes - the application plane, control plane, and data plane - each serving a distinct role in separating network functions.

Why each option
SDN architecture defines three primary planes - the application plane, control plane, and data plane - each serving a distinct role in separating network functions.
Management plane is a concept from traditional networking device architecture and is not one of the three defined planes in the SDN model.
The application plane is a core SDN layer where network applications and business logic reside, communicating policy intent downward to the controller via northbound APIs.
'Software plane' is not a recognized term in SDN architecture - no such plane exists in the standard three-plane model.
'Network plane' is not a defined SDN component - the three planes are the application, control, and data (infrastructure) planes.
The control plane is where the SDN controller operates, making centralized forwarding decisions and programmatically distributing them to the underlying data plane devices.
