Question 1190
At Willowbrook Education, a team reports that it corrected the following problem affecting student collaboration platforms: Splunk receives duplicate cloud events during connector recovery and runs multiple identical remediation playbooks. Which observation BEST verifies that the correction actually worked?
Explanation
Correct Answer
A repeated event results in one intended action and an auditable suppression record. This is the decisive evidence for the original problem: Splunk receives duplicate cloud events during connector recovery and runs multiple identical remediation playbooks. It verifies that the intended corrective control—Apply deduplication and idempotency controls in ingestion and orchestration—works in the relevant environment; a completed change ticket alone would not prove the outcome at Willowbrook Education.
Incorrect Answers
Low-confidence alerts cannot revoke identities; approved high-confidence cases are logged. This would be relevant evidence for a different failure: A response automation revokes user accounts based on one unverified alert and disrupts legitimate work, usually addressed by Add confidence thresholds and human approval before high-impact SOAR actions. It does not demonstrate that the current problem at Willowbrook Education was resolved. The specific required evidence is: A repeated event results in one intended action and an auditable suppression record.
A reviewer traces the full incident from triggering event to completed response. This would be relevant evidence for a different failure: An investigation needs to reconstruct actions across Splunk searches, detections, and connected security tools, usually addressed by Propagate case IDs and record playbook inputs, decisions, tool status, and outputs. It does not demonstrate that the current problem at Willowbrook Education was resolved. The specific required evidence is: A repeated event results in one intended action and an auditable suppression record.
A cross-source test exposes the complete timeline within the selected investigation window. This would be relevant evidence for a different failure: A SOC builds a Splunk search that uses inconsistent time zones and overlooks correlated authentication events, usually addressed by Normalize event time and choose relevant search windows and field mapping for correlation. It does not demonstrate that the current problem at Willowbrook Education was resolved. The specific required evidence is: A repeated event results in one intended action and an auditable suppression record.
