Question 620
An IS auditor is preparing recommendations after reviewing this situation: Management calls a readiness workshop a completed audit even though no testing or assurance opinion was planned. Which recommendation would BEST address the identified weakness?
- Refine duplicate detection with appropriate compound keys and review exceptions manually.
- Obtain a reproducible system-generated extract and corroborate key entries independently.
- Clarify the engagement type and issue only conclusions supported by the work actually performed.
- Expand the risk-based audit scope to include relevant customer controls and complementary provider assurances.
Explanation
Correct Answer
C:Clarify the engagement type and issue only conclusions supported by the work actually performed. The relevant control principle is: Advisory assessments and assurance engagements have different scopes, evidence needs and reporting obligations. A meaningful follow-up should establish: The final communication accurately distinguishes advice from an independently supported assurance opinion.
Incorrect Answers
A:Refine duplicate detection with appropriate compound keys and review exceptions manually. 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. In the present case, the most directly relevant recommendation is: Clarify the engagement type and issue only conclusions supported by the work actually performed. The governing distinction is: Advisory assessments and assurance engagements have different scopes, evidence needs and reporting obligations.
B:Obtain a reproducible system-generated extract and corroborate key entries independently. This would be relevant to a different issue such as: A system owner provides a screenshot of an access list without a timestamp or source-system identification. In the present case, the most directly relevant recommendation is: Clarify the engagement type and issue only conclusions supported by the work actually performed. The governing distinction is: Advisory assessments and assurance engagements have different scopes, evidence needs and reporting obligations.
D:Expand the risk-based audit scope to include relevant customer controls and complementary provider assurances. 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 recommendation is: Clarify the engagement type and issue only conclusions supported by the work actually performed. The governing distinction is: Advisory assessments and assurance engagements have different scopes, evidence needs and reporting obligations.
Question 621
An IS auditor evaluates this situation: A payroll release passes developer unit tests but has never completed end-to-end statutory deduction testing. Which audit principle MOST directly applies to this situation?
- Functional success does not demonstrate recoverability or continuity readiness.
