Exam ZDTE Topic 9 Question 39 Discussion

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.
