Question 290
During a Zscaler Zero Trust Exchange troubleshooting session, the team finds: A security collector slows during index maintenance and an integration repeatedly drops streamed events despite healthy source log generation. What assurance step should be included in future changes?
Explanation
Correct Answer
This safeguard mitigates siem stream backpressure requires buffer control: Plan SIEM receiver capacity for traffic peaks and alert on queue depth before compliance-critical events age out. The risk being controlled is: Receiver throughput and buffering capacity constrain delivery reliability, so downstream event loss can occur without any Zscaler enforcement issue. A safeguard for an unrelated failure would not address it.
Incorrect Answers
An external posture integration can fail independently of ZPA user authentication, leaving missing risk signals that must not be treated as compliant by default. “Monitor connector data freshness and use positive and missing-signal tests when integrating EDR or MDM compliance platforms” would remedy that alternative situation, but it would not correct the present issue: receiver throughput and buffering capacity constrain delivery reliability, so downstream event loss can occur without any Zscaler enforcement issue.
“Monitor source and destination counts and stream heartbeat separately from native security dashboard availability” is the supported response when nanolog Streaming Service or an equivalent supported integration needs correctly configured transport, log format and receiving pipeline independently of policy enforcement. Here the decisive response is “Plan SIEM receiver capacity for traffic peaks and alert on queue depth before compliance-critical events age out”, so that different intervention does not meet the stated requirement.
Federated authentication and user lifecycle provisioning are separate integrations; an IdP transition requires both sign-on and supported SCIM synchronization. “Exercise lifecycle integration tests and record any reconciliation failures after IdP vendor or tenant migrations” applies to that other condition. The reported evidence is a security collector slows during index maintenance and an integration repeatedly drops streamed events despite healthy source log generation; this alternative would address the wrong dependency.
