Question 440

An IS auditor evaluates this situation: A DLP tool blocks confidential document attachments but ignores similar files uploaded through approved web browsers. Which audit principle MOST directly applies to this situation?

  1. Incident governance should define regulatory communication and accountable legal decisions.
  2. Exfiltration control assessment should cover relevant channels, not only email.
  3. Data loss controls should be tied to classification, legitimate purpose and authorized exfiltration paths.
  4. Shared wireless credentials weaken accountability and reliable offboarding.

Explanation

Correct Answer

B:

Exfiltration control assessment should cover relevant channels, not only email. The corresponding audit procedure is: Map sensitive data flows, network egress methods and endpoint/browser policy enforcement.

Incorrect Answers

A:

Incident governance should define regulatory communication and accountable legal decisions. This would be relevant to a different issue such as: An organization discovers a reportable personal-data breach but no one knows who can authorize external notification. In the present case, the most directly relevant principle is: Exfiltration control assessment should cover relevant channels, not only email. The governing distinction is: Exfiltration control assessment should cover relevant channels, not only email.

C:

Data loss controls should be tied to classification, legitimate purpose and authorized exfiltration paths. This would be relevant to a different issue such as: A customer service portal allows employees to export unrestricted copies of all customer identity documents. In the present case, the most directly relevant principle is: Exfiltration control assessment should cover relevant channels, not only email. The governing distinction is: Exfiltration control assessment should cover relevant channels, not only email.

D:

Shared wireless credentials weaken accountability and reliable offboarding. This would be relevant to a different issue such as: A branch wireless network uses a shared password disclosed to vendors and former employees. In the present case, the most directly relevant principle is: Exfiltration control assessment should cover relevant channels, not only email. The governing distinction is: Exfiltration control assessment should cover relevant channels, not only email.

Question 441

Management reports that this issue has been corrected: A critical provider exits the market and the customer has no usable data export or transition rights. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. The selected vendor meets mandatory criteria or has approved documented mitigation.
  2. A rehearsal demonstrates recoverable data and an operationally feasible provider transition.
  3. Board risk views disclose significant exposures without misleading cross-category comparisons.
  4. Procurement decisions cite capacity forecasts and approved constraints rather than assumptions.

Explanation

Correct Answer

B:

A rehearsal demonstrates recoverable data and an operationally feasible provider transition. It addresses it vendor management. Underlying audit concern: Vendor exit planning is necessary to manage concentration and operational continuity risk.

Incorrect Answers

A:

The selected vendor meets mandatory criteria or has approved documented mitigation. This would be relevant to a different issue such as: Procurement selects the lowest-cost cloud vendor while ignoring prior security incidents and regulatory audit rights. In the present case, the most directly relevant verification is: A rehearsal demonstrates recoverable data and an operationally feasible provider transition. The governing distinction is: Vendor exit planning is necessary to manage concentration and operational continuity risk.

C:

Board risk views disclose significant exposures without misleading cross-category comparisons. This would be relevant to a different issue such as: An enterprise applies one numeric risk score to cyber, safety and privacy exposures despite different materiality definitions. In the present case, the most directly relevant verification is: A rehearsal demonstrates recoverable data and an operationally feasible provider transition. The governing distinction is: Vendor exit planning is necessary to manage concentration and operational continuity risk.

D:

Procurement decisions cite capacity forecasts and approved constraints rather than assumptions. This would be relevant to a different issue such as: An infrastructure team buys additional servers while idle compatible capacity remains unallocated in another business unit. In the present case, the most directly relevant verification is: A rehearsal demonstrates recoverable data and an operationally feasible provider transition. The governing distinction is: Vendor exit planning is necessary to manage concentration and operational continuity risk.

Question 442

Management reports that this issue has been corrected: An ERP cutover leaves the old interface running and duplicates orders in both systems. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Unauthorized promotions fail while approved releases retain auditable provenance.
  2. Representative imaging workflow meets agreed performance and data-handling requirements.
  3. A migrated encrypted sample is accessible to authorized users and remains protected.
  4. Each order appears once in the target system with reconciled business totals.

Explanation

Correct Answer

D:

Each order appears once in the target system with reconciled business totals. It addresses system migration, infrastructure deployment, and data conversion. Underlying audit concern: Cutover controls must manage transactional boundaries and avoid unintended dual processing.

Incorrect Answers

A:

Unauthorized promotions fail while approved releases retain auditable provenance. This would be relevant to a different issue such as: A DevOps team deploys from automated pipelines with no independent approval for sensitive production promotions. In the present case, the most directly relevant verification is: Each order appears once in the target system with reconciled business totals. The governing distinction is: Cutover controls must manage transactional boundaries and avoid unintended dual processing.

B:

Representative imaging workflow meets agreed performance and data-handling requirements. This would be relevant to a different issue such as: A hospital chooses a cloud imaging service without confirming network reliability or clinical response needs. In the present case, the most directly relevant verification is: Each order appears once in the target system with reconciled business totals. The governing distinction is: Cutover controls must manage transactional boundaries and avoid unintended dual processing.

C:

A migrated encrypted sample is accessible to authorized users and remains protected. This would be relevant to a different issue such as: A cloud move assumes existing encryption keys will work in the target without import or custody testing. In the present case, the most directly relevant verification is: Each order appears once in the target system with reconciled business totals. The governing distinction is: Cutover controls must manage transactional boundaries and avoid unintended dual processing.

Question 443

An IS auditor evaluates this situation: Auditors receive conflicting statements from administrators about whether an encryption setting was enabled during the test period. Which audit principle MOST directly applies to this situation?

  1. Sample conclusions must reflect observed deviations and appropriate uncertainty.
  2. Inquiry alone is weaker than independently corroborated technical evidence.
  3. Analytics rules need valid business keys and exception handling to avoid false conclusions.
  4. Service-provider assurance must cover the actual period and relevant control objectives.

Explanation

Correct Answer

B:

Inquiry alone is weaker than independently corroborated technical evidence. The corresponding audit procedure is: Review time-stamped configuration history, effective encryption status and relevant system logs.

Incorrect Answers

A:

Sample conclusions must reflect observed deviations and appropriate uncertainty. This would be relevant to a different issue such as: A sample of authorized changes contains failures, yet the auditor extrapolates a zero-percent exception rate. In the present case, the most directly relevant principle is: Inquiry alone is weaker than independently corroborated technical evidence. The governing distinction is: Inquiry alone is weaker than independently corroborated technical evidence.

C:

Analytics rules need valid business keys and exception handling to avoid false conclusions. 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 principle is: Inquiry alone is weaker than independently corroborated technical evidence. The governing distinction is: Inquiry alone is weaker than independently corroborated technical evidence.

D:

Service-provider assurance must cover the actual period and relevant control objectives. This would be relevant to a different issue such as: A supplier gives the audit team a third-party control report that expired before the review period. In the present case, the most directly relevant principle is: Inquiry alone is weaker than independently corroborated technical evidence. The governing distinction is: Inquiry alone is weaker than independently corroborated technical evidence.

Question 444

Before reaching an audit conclusion, consider: A regional outage exercise reveals that business partners were never included in the communications tree. Which evidence should the auditor review FIRST to evaluate this risk?

  1. Review spreadsheet logic, versioning, reconciliations, owners and manual overrides.
  2. Examine invocation criteria, contact trees, authority matrix and availability assumptions.
  3. Inspect backup integrity, encryption keys, retention copies and last restore test.
  4. Review partner contacts, contract notices, channels and exercise feedback.

Explanation

Correct Answer

D:

Review partner contacts, contract notices, channels and exercise feedback. The governing principle is: Continuity communication should address external dependencies and affected stakeholders.

Incorrect Answers

This would be relevant to a different issue such as: A spreadsheet with editable formulas calculates regulatory capital but has no validation or change history. In the present case, the most directly relevant audit step is: Review partner contacts, contract notices, channels and exercise feedback. The governing distinction is: Continuity communication should address external dependencies and affected stakeholders.

B:

Examine invocation criteria, contact trees, authority matrix and availability assumptions. This would be relevant to a different issue such as: A continuity plan lists the chief executive as the only emergency decision authority with no alternate. In the present case, the most directly relevant audit step is: Review partner contacts, contract notices, channels and exercise feedback. The governing distinction is: Continuity communication should address external dependencies and affected stakeholders.

C:

Inspect backup integrity, encryption keys, retention copies and last restore test. This would be relevant to a different issue such as: An enterprise calls backups successful because jobs complete, but no recent restoration test has been performed. In the present case, the most directly relevant audit step is: Review partner contacts, contract notices, channels and exercise feedback. The governing distinction is: Continuity communication should address external dependencies and affected stakeholders.

Question 445

Management reports that this issue has been corrected: A supplier dependency map omits a critical cloud DNS service used by every customer-facing application. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Only authorized destinations receive necessary data and workflow use is logged.
  2. A representative provider outage does not disable every required inter-site service.
  3. Business totals reconcile before and after authorized schema changes.
  4. A controlled DNS failure exercise meets continuity expectations or documents accepted gaps.

Explanation

Correct Answer

D:

A controlled DNS failure exercise meets continuity expectations or documents accepted gaps. It addresses system and operational resilience. Underlying audit concern: Resilience planning must include external and supporting infrastructure dependencies.

Incorrect Answers

A:

Only authorized destinations receive necessary data and workflow use is logged.
