Correct answer: Exposes interfaces from an SDN controller to network applications.
Why this is the answer
A northbound API (Application Programming Interface) allows applications and services to communicate with and program the SDN controller. This enables network applications to request services, define policies, and interact with the underlying network infrastructure managed by the controller. It essentially provides a higher-level, abstract view of the network to applications. "Depends on centralized provisioning and configuration" describes a characteristic of SDN controllers, not a function of a northbound API itself. "Performs software upgrades and file restoration" describes maintenance tasks, not the core purpose of a northbound API. "Enables distributed configuration processing" is incorrect; SDN aims for centralized control, and northbound APIs facilitate that centralized control by exposing it to applications.
