Question 90

An IS auditor is preparing recommendations after reviewing this situation: A chief technology officer both accepts enterprise cyber risk and certifies the independence of the risk oversight function. Which recommendation would BEST address the identified weakness?

  1. Recommend clear separation of risk acceptance from independent oversight and assurance.
  2. Recommend an accountable data steward and controlled master-data quality process.
  3. Recommend an accountable portfolio review that documents strategic rationale and benefit measures.
  4. Recommend lifecycle deletion and exception enforcement across all controlled storage locations.

Explanation

Correct Answer

A:

Recommend clear separation of risk acceptance from independent oversight and assurance. The relevant control principle is: Governance should define risk ownership and objective challenge across accountable roles. A meaningful follow-up should establish: Approvals show authorized risk owners and recorded independent challenge for material exposures.

Incorrect Answers

B:

Recommend an accountable data steward and controlled master-data quality process. This would be relevant to a different issue such as: Multiple business units publish different values for the same customer account status without a nominated data steward. In the present case, the most directly relevant recommendation is: Recommend clear separation of risk acceptance from independent oversight and assurance. The governing distinction is: Governance should define risk ownership and objective challenge across accountable roles.

C:

Recommend an accountable portfolio review that documents strategic rationale and benefit measures. This would be relevant to a different issue such as: A technology steering group approves projects without showing how they support the organization's strategic priorities. In the present case, the most directly relevant recommendation is: Recommend clear separation of risk acceptance from independent oversight and assurance. The governing distinction is: Governance should define risk ownership and objective challenge across accountable roles.

D:

Recommend lifecycle deletion and exception enforcement across all controlled storage locations. This would be relevant to a different issue such as: A cloud analytics environment retains raw regulated data after the approved business retention period. In the present case, the most directly relevant recommendation is: Recommend clear separation of risk acceptance from independent oversight and assurance. The governing distinction is: Governance should define risk ownership and objective challenge across accountable roles.

Question 91

An IS auditor evaluates this situation: A financial reporting controls audit tests only the cloud provider's availability status but ignores the customer's application controls. Which audit principle MOST directly applies to this situation?

  1. Audit evidence reliability depends on source, integrity, relevance and timing.
  2. An audit must cover the controls relevant to the stated reporting objective across service-provider boundaries.
  3. A detective control must include timely response and accountability to reduce exposure.
  4. Advisory assessments and assurance engagements have different scopes, evidence needs and reporting obligations.

Explanation

Correct Answer

B:

An audit must cover the controls relevant to the stated reporting objective across service-provider boundaries. The corresponding audit procedure is: Map financial assertions, provider responsibilities and customer-controlled configuration or access processes.

Incorrect Answers

A:

Audit evidence reliability depends on source, integrity, relevance and timing. 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 principle is: An audit must cover the controls relevant to the stated reporting objective across service-provider boundaries. The governing distinction is: An audit must cover the controls relevant to the stated reporting objective across service-provider boundaries.

C:

A detective control must include timely response and accountability to reduce exposure. This would be relevant to a different issue such as: A monitoring alert is generated for suspicious transfers, but no owner is assigned to investigate or close it. In the present case, the most directly relevant principle is: An audit must cover the controls relevant to the stated reporting objective across service-provider boundaries. The governing distinction is: An audit must cover the controls relevant to the stated reporting objective across service-provider boundaries.

D:

Advisory assessments and assurance engagements have different scopes, evidence needs and reporting obligations. This would be relevant to a different issue such as: Management calls a readiness workshop a completed audit even though no testing or assurance opinion was planned. In the present case, the most directly relevant principle is: An audit must cover the controls relevant to the stated reporting objective across service-provider boundaries. The governing distinction is: An audit must cover the controls relevant to the stated reporting objective across service-provider boundaries.

Question 92

Management reports that this issue has been corrected: Management calls a readiness workshop a completed audit even though no testing or assurance opinion was planned. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Workpapers trace each material reporting risk to an appropriate control and test result.
  2. The final communication accurately distinguishes advice from an independently supported assurance opinion.
  3. Known test events appear and processing totals reconcile after ingestion recovery.
  4. A test change cannot bypass approval, and independent exception review still operates.

Explanation

Correct Answer

B:

The final communication accurately distinguishes advice from an independently supported assurance opinion. It addresses types of audits, assessments, and reviews. Underlying audit concern: Advisory assessments and assurance engagements have different scopes, evidence needs and reporting obligations.

Incorrect Answers

A:

Workpapers trace each material reporting risk to an appropriate control and test result.

In the present case, the most directly relevant verification is: The final communication accurately distinguishes advice from an independently supported assurance opinion. The governing distinction is: Advisory assessments and assurance engagements have different scopes, evidence needs and reporting obligations.

D:

A test change cannot bypass approval, and independent exception review still operates. This would be relevant to a different issue such as: A payroll system uses post-payment anomaly reports but has no approval requirement for changing bank accounts. In the present case, the most directly relevant verification is: The final communication accurately distinguishes advice from an independently supported assurance opinion. The governing distinction is: Advisory assessments and assurance engagements have different scopes, evidence needs and reporting obligations.

Question 93

Management reports that this issue has been corrected: A sales system's backup schedule is chosen before the business determines acceptable data loss. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. A recovery rehearsal restores the complete service within the approved RTO.
  2. Restoration passes transactional integrity and reconciliation tests.
  3. A restore exercise measures actual data currency against the approved loss limit.
  4. An anticipated high-load period does not exhaust storage and restore capability remains intact.

Explanation

Correct Answer

C:

A restore exercise measures actual data currency against the approved loss limit. It addresses business impact analysis. Underlying audit concern: RPO should be derived from business impact and transactional tolerance, not backup convenience.

Incorrect Answers

A:

A recovery rehearsal restores the complete service within the approved RTO. This would be relevant to a different issue such as: A business owner specifies a one-hour RTO but has never identified which external dependencies must also be restored. In the present case, the most directly relevant verification is: A restore exercise measures actual data currency against the approved loss limit. The governing distinction is: RPO should be derived from business impact and transactional tolerance, not backup convenience.

B:

Restoration passes transactional integrity and reconciliation tests. This would be relevant to a different issue such as: A company copies database files nightly while transactions remain active, producing inconsistent backups. In the present case, the most directly relevant verification is: A restore exercise measures actual data currency against the approved loss limit. The governing distinction is: RPO should be derived from business impact and transactional tolerance, not backup convenience.

D:

An anticipated high-load period does not exhaust storage and restore capability remains intact. This would be relevant to a different issue such as: Database transaction logs fill the only disk volume and cause a payment service outage. In the present case, the most directly relevant verification is: A restore exercise measures actual data currency against the approved loss limit. The governing distinction is: RPO should be derived from business impact and transactional tolerance, not backup convenience.

Question 94

Management reports that this issue has been corrected: A nightly settlement batch fails halfway but the scheduler marks the entire chain successful. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Unauthorized script edits are denied and authorized revisions are traceable.
  2. Each retired device reconciles to approved erasure or destruction evidence and authorized release.
  3. An injected failure prevents false success and all unsettled transactions are accounted for.
  4. A recovery test completes reconciled business transactions within required limits.

Explanation

Correct Answer

C:

An injected failure prevents false success and all unsettled transactions are accounted for. It addresses job scheduling and production process automation. Underlying audit concern: Automated jobs require dependency, exception and completion controls for reliable processing.

Incorrect Answers

A:

Unauthorized script edits are denied and authorized revisions are traceable. This would be relevant to a different issue such as: An operator can edit scheduled payroll scripts directly in production without independent approval. In the present case, the most directly relevant verification is: An injected failure prevents false success and all unsettled transactions are accounted for. The governing distinction is: Automated jobs require dependency, exception and completion controls for reliable processing.

B:

Each retired device reconciles to approved erasure or destruction evidence and authorized release. This would be relevant to a different issue such as: A retail chain replaces laptops but leaves decommissioned drives untracked with a disposal contractor. In the present case, the most directly relevant verification is: An injected failure prevents false success and all unsettled transactions are accounted for. The governing distinction is: Automated jobs require dependency, exception and completion controls for reliable processing.

D:

A recovery test completes reconciled business transactions within required limits.

  2. Recommend dependency-aware recovery requirements and feasible coordinated timelines.
  3. Recommend an accurate component dependency inventory and risk review of single points of failure.
  4. Recommend prechange compatibility validation and a controlled fallback path.

Explanation

Correct Answer

C:

Recommend an accurate component dependency inventory and risk review of single points of failure. The relevant control principle is: End-to-end service availability depends on all critical infrastructure and application components. A meaningful follow-up should establish: An end-to-end fault analysis covers each critical dependency and its recovery plan.

Incorrect Answers

A:
