Question 660
During a security incident tabletop exercise at Prairie Health Network, engineers say that they resolved this finding: An ingestion pipeline duplicates cloud events during retry and inflates detection counts. Which result provides the STRONGEST acceptance evidence?
Explanation
Correct Answer
Replaying the same source batch does not create duplicate incident counts. This is the decisive evidence for the original problem: An ingestion pipeline duplicates cloud events during retry and inflates detection counts. It verifies that the intended corrective control—Define supported event identity handling, checkpointing, and duplicate detection in the collection workflow—works in the relevant environment; a completed change ticket alone would not prove the outcome at Prairie Health Network.
Incorrect Answers
A newly generated cloud audit event appears in the intended searchable index. This would be relevant evidence for a different failure: A cloud security connector has valid API access but Splunk receives no new events after initial onboarding, usually addressed by Check collection credentials, input configuration, time range, and network reachability. It does not demonstrate that the current problem at Prairie Health Network was resolved. The specific required evidence is: Replaying the same source batch does not create duplicate incident counts.
An authenticated event is ingested after rotation while the revoked token fails. This would be relevant evidence for a different failure: Cloud log collection unexpectedly stops because the Splunk input token was rotated, usually addressed by Refresh the configured ingestion authentication securely and monitor token expiry. It does not demonstrate that the current problem at Prairie Health Network was resolved. The specific required evidence is: Replaying the same source batch does not create duplicate incident counts.
A role-filtered search attributes each test event to the correct cloud account. This would be relevant evidence for a different failure: Two cloud accounts send logs into the same Splunk index but there is no trustworthy source identification, usually addressed by Tag data with verified account and source metadata during ingestion and validate field extraction. It does not demonstrate that the current problem at Prairie Health Network was resolved. The specific required evidence is: Replaying the same source batch does not create duplicate incident counts.
