Question 510

An IS auditor is preparing recommendations after reviewing this situation: Two data centers have separate buildings but share one telecom carrier and underground duct. Which recommendation would BEST address the identified weakness?

  1. Recommend independent communications paths or explicit mitigation for shared exposure.
  2. Recommend integrated DR connectivity testing and remediation of broken dependencies.
  3. Recommend tested alternate operator coverage and controlled emergency access.
  4. Recommend durable queuing, replay controls and dead-letter monitoring.

Explanation

Correct Answer

A:

Recommend independent communications paths or explicit mitigation for shared exposure. The relevant control principle is: Operational resilience requires evaluation of common-mode dependencies. A meaningful follow-up should establish: A representative provider outage does not disable every required inter-site service.

Incorrect Answers

B:

Recommend integrated DR connectivity testing and remediation of broken dependencies. This would be relevant to a different issue such as: A recovery site has servers but no validated link to the payment network after a facility loss. In the present case, the most directly relevant recommendation is: Recommend independent communications paths or explicit mitigation for shared exposure. The governing distinction is: Operational resilience requires evaluation of common-mode dependencies.

C:

Recommend tested alternate operator coverage and controlled emergency access. This would be relevant to a different issue such as: A highly available application uses only one privileged administrator who is unavailable during a holiday. In the present case, the most directly relevant recommendation is: Recommend independent communications paths or explicit mitigation for shared exposure. The governing distinction is: Operational resilience requires evaluation of common-mode dependencies.

D:

Recommend durable queuing, replay controls and dead-letter monitoring. This would be relevant to a different issue such as: A cloud event bus drops messages during an outage and consuming systems never replay them. In the present case, the most directly relevant recommendation is: Recommend independent communications paths or explicit mitigation for shared exposure. The governing distinction is: Operational resilience requires evaluation of common-mode dependencies.

Question 511

An IS auditor is preparing recommendations after reviewing this situation: Auditors receive conflicting statements from administrators about whether an encryption setting was enabled during the test period. Which recommendation would BEST address the identified weakness?

  1. Independently retest the agreed corrective action and record any residual exposure.
  2. Use approved minimal-data or masked analysis within a controlled audit environment.
  3. Have the audit director assign an independent reviewer and disclose the conflict to appropriate oversight.
  4. Resolve the conflicting accounts using contemporaneous authoritative records.

Explanation

Correct Answer

D:

Resolve the conflicting accounts using contemporaneous authoritative records. The relevant control principle is: Inquiry alone is weaker than independently corroborated technical evidence. A meaningful follow-up should establish: The audit conclusion cites verifiable settings effective during the scope period.

Incorrect Answers

A:

Independently retest the agreed corrective action and record any residual exposure. This would be relevant to a different issue such as: Post-audit follow-up marks a critical password weakness closed solely because management sent a completion email. In the present case, the most directly relevant recommendation is: Resolve the conflicting accounts using contemporaneous authoritative records. The governing distinction is: Inquiry alone is weaker than independently corroborated technical evidence.

B:

Use approved minimal-data or masked analysis within a controlled audit environment. This would be relevant to a different issue such as: An auditor exports personally identifiable records to an unsecured laptop for analytics testing. In the present case, the most directly relevant recommendation is: Resolve the conflicting accounts using contemporaneous authoritative records. The governing distinction is: Inquiry alone is weaker than independently corroborated technical evidence.

C:

Have the audit director assign an independent reviewer and disclose the conflict to appropriate oversight. This would be relevant to a different issue such as: An internal auditor helped configure the privileged-access system now scheduled for an assurance review. In the present case, the most directly relevant recommendation is: Resolve the conflicting accounts using contemporaneous authoritative records. The governing distinction is: Inquiry alone is weaker than independently corroborated technical evidence.

Question 512

An IS auditor is preparing recommendations after reviewing this situation: Database transaction logs fill the only disk volume and cause a payment service outage. Which recommendation would BEST address the identified weakness?

  1. Recommend auditable emergency change controls with post-implementation oversight.
  2. Recommend limiting the integration to approved read permissions with reviewed exceptions.
  3. Recommend proactive log management and capacity alarms without impairing recovery.
  4. Recommend periodic configuration item reconciliation and owner attestation.

Explanation

Correct Answer

C:

Question 515

An IS auditor evaluates this situation: Fieldwork expands to a new subsidiary without updating the approved engagement scope or communicating budget impact. Which audit principle MOST directly applies to this situation?

  1. Quality supervision requires sufficient review before relying on engagement conclusions.
  2. Judgmentally selected favorable examples cannot support a population-wide effectiveness conclusion.
  3. Risk-based audit planning is dynamic when business context and material exposures change.
  4. Material scope changes require controlled approval, resource assessment and stakeholder communication.

Explanation

Correct Answer

D:

Material scope changes require controlled approval, resource assessment and stakeholder communication. The corresponding audit procedure is: Compare approved charter, new testing requests, risk justification and effort forecast.

Incorrect Answers

A:

Quality supervision requires sufficient review before relying on engagement conclusions. This would be relevant to a different issue such as: An audit manager signs the report although a junior tester's exceptions have not received independent review. In the present case, the most directly relevant principle is: Material scope changes require controlled approval, resource assessment and stakeholder communication.

In the present case, the most directly relevant verification is: Engagement scope and limitation disclosures show material risks were not silently omitted. The governing distinction is: Audit scope must be based on independent assessment of relevant risk rather than auditee preference.

Question 519

Before reaching an audit conclusion, consider: A critical provider exits the market and the customer has no usable data export or transition rights. Which evidence should the auditor review FIRST to evaluate this risk?

  1. Inspect target architecture, proposed exception scope and affected trust boundaries.
  2. Review loss scenarios, duration estimates and board-approved risk limits.
  3. Review subprocessor lists, data flows, consent terms and audit rights.
  4. Inspect portability clauses, data format, transition timing and alternative service readiness.

Explanation

Correct Answer

D:

Inspect portability clauses, data format, transition timing and alternative service readiness. The governing principle is: Vendor exit planning is necessary to manage concentration and operational continuity risk.

Incorrect Answers

A:

Inspect target architecture, proposed exception scope and affected trust boundaries. This would be relevant to a different issue such as: A cloud architecture exception bypasses the organization's target zero-trust network segmentation without review. In the present case, the most directly relevant audit step is: Inspect portability clauses, data format, transition timing and alternative service readiness. The governing distinction is: Vendor exit planning is necessary to manage concentration and operational continuity risk.

B:

Review loss scenarios, duration estimates and board-approved risk limits. This would be relevant to a different issue such as: A department labels a customer outage risk acceptable because its probability is low without evaluating financial impact. In the present case, the most directly relevant audit step is: Inspect portability clauses, data format, transition timing and alternative service readiness. The governing distinction is: Vendor exit planning is necessary to manage concentration and operational continuity risk.

C:

Review subprocessor lists, data flows, consent terms and audit rights. This would be relevant to a different issue such as: A subcontractor stores confidential records in a region excluded by the prime provider's contract. In the present case, the most directly relevant audit step is: Inspect portability clauses, data format, transition timing and alternative service readiness. The governing distinction is: Vendor exit planning is necessary to manage concentration and operational continuity risk.

Question 520

Management reports that this issue has been corrected: An internal portal outage follows certificate expiration despite an automated renewal job that reported success. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Repeat infections decline and validated corrective controls remain effective.
  2. An unauthorized administrator cannot export or use the CA signing key.
  3. The reconstructed sequence includes initial access, activity and response without unexplained gaps.
  4. A controlled renewal leaves the active endpoint with a valid trusted certificate.

Explanation

Correct Answer

D:

A controlled renewal leaves the active endpoint with a valid trusted certificate. It addresses public key infrastructure. Underlying audit concern: PKI monitoring should validate deployed certificates and trust paths, not just job status.

Incorrect Answers

A:

Repeat infections decline and validated corrective controls remain effective. This would be relevant to a different issue such as: After a malware outbreak is closed, identical infections recur because no root-cause or control improvement work is assigned. In the present case, the most directly relevant verification is: A controlled renewal leaves the active endpoint with a valid trusted certificate.
