Isaca CISA Practice Test 52
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?
- Recommend independent communications paths or explicit mitigation for shared exposure.
- Recommend integrated DR connectivity testing and remediation of broken dependencies.
- Recommend tested alternate operator coverage and controlled emergency access.
- 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?
- Independently retest the agreed corrective action and record any residual exposure.
- Use approved minimal-data or masked analysis within a controlled audit environment.
- Have the audit director assign an independent reviewer and disclose the conflict to appropriate oversight.
- 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.
