What role does an App Connector serve?

An App Connector is the ZPA component that sits near private applications and establishes outbound-only connections to the Zscaler cloud. It brokers application reachability without exposing inbound ports or public IP addresses, allowing users to connect to applications rather than networks. Option D (App Connectors mediate seamless communication for applications, services and data sources) is correct because App Connectors mediate communication to private applications, services, and data sources.

Why the other options are incorrect:

A. App Connectors enforce security policies for traffic destined for SaaS applications: SaaS applications are handled by ZIA controls such as URL Filtering, Cloud App Control, and DLP, not by ZPA App Connectors.

B. App Connectors enable user experience monitoring for all applications: User-experience monitoring is ZDX’s job. App Connectors provide the outbound broker path that lets users reach private applications.

C. App Connectors expose a public IP for users to connect to for private application access: Publishing a public IP exposes an attack surface; ZPA avoids that by using inside-out connector connectivity.
