Exam ZDTE Topic 1 Question 11 Discussion

Zscaler Private Access (ZPA) uses the Log Streaming Service (LSS) to deliver ZPA logs (such as user activity and connector/authentication logs) to external SIEM and analytics platforms. LSS relies on a ZPA App Connector as the local relay between the ZPA service and the downstream log receiver. If network connectivity between ZPA and the local App Connector is interrupted, log delivery may be temporarily disrupted.
According to Zscaler integration guidance, when connectivity between ZPA and the local App Connectors is restored, LSS can retransmit up to 15 minutes of previously undelivered log data, although this retransmission is not guaranteed in all circumstances. This limited replay window is designed to provide reasonable resilience for short outages without requiring large local storage on the connector.
The 15-minute buffer applies specifically to ZPA log streaming scenarios and is distinct from longer-term log retention in Zscaler's logging cluster or external SIEM. Options A, C, and D overstate the supported replay duration and do not match Zscaler's documented behavior. To minimize log gaps beyond this 15-minute window, Zscaler recommends resilient network paths for App Connectors and careful monitoring of connector health so that LSS can operate continuously.
