Software-defined networking architecture is used for cost-effective, adaptable and easily manageable applications. In which two software-defined networks is SDN commonly used? (Choose two.)

Control network refers to the control plane within the SDN architecture itself, not a type of real-world network where SDN is deployed.

Mobile networks use SDN to support network function virtualization and dynamic resource allocation across radio access and core network segments, making centralized programmability essential.

Wide area networks leverage SDN (commonly implemented as SD-WAN) to provide centralized policy management, dynamic path selection, and cost-efficient transport across geographically distributed sites.

Application network describes the application layer or application plane in the SDN model, not a distinct network type that SDN is deployed into.

Metro networks are not a primary or commonly cited SDN deployment target in standard SDN literature compared to mobile and WAN environments.
