Question 550
Management reports that this issue has been corrected: A continuous monitoring dashboard reports zero failed access attempts because its collection job stopped three days ago. Which result would provide the STRONGEST assurance that the issue is corrected?
- Reported exceptions are reproducible and supported by transaction evidence rather than model scores alone.
- The final report enables leadership to understand exposure and track a measurable remediation.
- Workpapers trace each material reporting risk to an appropriate control and test result.
- Known test events appear and processing totals reconcile after ingestion recovery.
Explanation
Correct Answer
D:Known test events appear and processing totals reconcile after ingestion recovery. It addresses audit data analytics. Underlying audit concern: A zero-exception result is unreliable if data completeness and pipeline health are unverified.
Incorrect Answers
A:Reported exceptions are reproducible and supported by transaction evidence rather than model scores alone. This would be relevant to a different issue such as: An anomaly model ranks high-value payments as suspicious but the auditor cannot explain its scoring or false-positive rate. In the present case, the most directly relevant verification is: Known test events appear and processing totals reconcile after ingestion recovery. The governing distinction is: A zero-exception result is unreliable if data completeness and pipeline health are unverified.
B:The final report enables leadership to understand exposure and track a measurable remediation. This would be relevant to a different issue such as: A report calls a firewall exception critical but provides no business impact, cause or responsible owner. In the present case, the most directly relevant verification is: Known test events appear and processing totals reconcile after ingestion recovery. The governing distinction is: A zero-exception result is unreliable if data completeness and pipeline health are unverified.
C:Workpapers trace each material reporting risk to an appropriate control and test result. This would be relevant to a different issue such as: A financial reporting controls audit tests only the cloud provider's availability status but ignores the customer's application controls. In the present case, the most directly relevant verification is: Known test events appear and processing totals reconcile after ingestion recovery.
