ZDTE Exam Dumps - Zscaler Digital Transformation Engineer

Zscaler provides specialized Log Streaming Services to export logs from the Zero Trust Exchange into external SIEM or log-analytics platforms for long-term storage and advanced analysis. For Zscaler Private Access (ZPA), the Log Streaming Service (LSS) forwards user activity, user status, App Connector metrics, and other diagnostic logs to a log receiver, which is typically a SIEM, syslog collector, or similar downstream system. Zscaler documentation notes that customers use LSS specifically to store logs beyond the default cloud retention period and to support external analytics and compliance use cases.

On the ZIA side, Nanolog Streaming Service (NSS) fulfills a similar purpose, streaming web and firewall logs from the Zscaler Nanolog cluster into SIEM solutions. Together, these streaming services give organizations centralized visibility and long-term retention while keeping the Zscaler cloud optimized for inline inspection and near-term reporting.

Role-Based Access Control (RBAC) governs who can view or manage configurations, not how logs are exported. The Zero Trust Exchange query or insights interfaces are used for in-portal searching and visualization, and “Log Recovery Service” is not the Zscaler term used for SIEM integration in ZDTE materials. Therefore, Log Streaming Services is the correct answer because it is the named mechanism for streaming Zscaler logs to external SIEM platforms for long-term storage.

The Zscaler Digital Transformation study guides describe the Zero Trust Exchange using the conceptual model of “Brains and Engines.” Engines are the inline enforcement components—ZIA Public Service Edges, ZPA Service Edges, App Connectors, etc.—that sit in the data path to forward traffic, apply policy, and perform inspection.

The “Brains” side, however, represents the cloud control and intelligence plane. Here Zscaler hosts components such as Central Authority, policy and configuration stores, analytics engines, and, critically, the Logging and Reporting infrastructure (Nanolog clusters, Log Streaming Service, and analytics dashboards). The documentation explicitly associates log collection, compression, forwarding to SIEM/SOAR platforms, and long-term analytics with this centralized cloud layer rather than the enforcement engines themselves.

Engines generate rich telemetry, but they stream it back to the brains layer, where it is normalized, indexed, retained, and made searchable for investigations, compliance, and performance analysis. OneAPI is an access interface, not the location of the logging services, and “Memory” is not a formal architectural construct in the Zscaler model. Therefore, in the official architecture view taught for the exam, logging services clearly reside in the Brains component of the platform.
