At which level of the Zscaler Architecture do the Zscaler APIs sit?

The Zscaler architecture is composed of three main planes: the Data Plane (ZIA Public Service Edges), the Statistics Plane (Nanolog Cluster), and the Control Plane (Central Authority). The Central Authority (CA) acts as the brain of the Zscaler cloud, hosting the policy and configuration management interface for administrators. The Zscaler APIs, which allow for programmatic configuration, management, and monitoring, are a component of this Control Plane, providing access to the functionalities managed by the CA.

A. The Enforcement Plane (Data Plane) is where user traffic is processed and security policies are applied in real-time, not where the management APIs are hosted.

B. The Nanolog Cluster is part of the logging and statistics plane, responsible for storing and indexing transaction logs for reporting, not for configuration via APIs.

D. Data Fabric is not a standard term for one of the three core architectural planes in the official Zscaler documentation.
