In the present case, the most directly relevant recommendation is: Recommend prioritized alert ownership, response playbooks and independent oversight. The governing distinction is: Detection requires an accountable response workflow to reduce business impact.

Question 685

Management reports that this issue has been corrected: An auditor cannot decide whether to review a high-impact legacy billing interface because no recent incidents are recorded. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Confirmed duplicates and legitimate reversals are separately documented and reproducible.
  2. A revised audit universe and schedule explicitly cover newly material acquisition risks.
  3. The final communication accurately distinguishes advice from an independently supported assurance opinion.
  4. The audit priority follows supported exposure and control evidence, not incident counts alone.

Explanation

Correct Answer

D:

The audit priority follows supported exposure and control evidence, not incident counts alone. It addresses risk-based audit planning. Underlying audit concern: Absence of reported incidents is not proof of low inherent or residual risk.

Incorrect Answers

A:

Confirmed duplicates and legitimate reversals are separately documented and reproducible. This would be relevant to a different issue such as: An auditor flags duplicated supplier invoices by invoice number alone and ignores vendor identifiers and credit notes.
