Question 790

Before reaching an audit conclusion, consider: An attacker encrypts production files and online backups because both use the same compromised admin identity. Which evidence should the auditor review FIRST to evaluate this risk?

  1. Map DNS architecture, cache behavior, alternate paths and outage records.
  2. Review network routes, partner links, certificates and recovery site failover plans.
  3. Inspect backup privilege boundaries, deletion rights and ransomware recovery design.
  4. Review backup method, transaction logs, quiescing support and restore checks.

Explanation

Correct Answer

C:

Inspect backup privilege boundaries, deletion rights and ransomware recovery design. The governing principle is: Backup resilience needs separation and protected immutable or offline recovery copies.

Incorrect Answers

A:

Map DNS architecture, cache behavior, alternate paths and outage records. This would be relevant to a different issue such as: A redundant web cluster shares one DNS resolver and becomes inaccessible when that resolver fails. In the present case, the most directly relevant audit step is: Inspect backup privilege boundaries, deletion rights and ransomware recovery design. The governing distinction is: Backup resilience needs separation and protected immutable or offline recovery copies.

B:

Review network routes, partner links, certificates and recovery site failover plans. 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 audit step is: Inspect backup privilege boundaries, deletion rights and ransomware recovery design. The governing distinction is: Backup resilience needs separation and protected immutable or offline recovery copies.

D:

Review backup method, transaction logs, quiescing support and restore checks. 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 audit step is: Inspect backup privilege boundaries, deletion rights and ransomware recovery design. The governing distinction is: Backup resilience needs separation and protected immutable or offline recovery copies.

Question 791

Before reaching an audit conclusion, consider: A recovery site has servers but no validated link to the payment network after a facility loss. Which evidence should the auditor review FIRST to evaluate this risk?

  1. Inspect dependency maps, test coverage, change approvals and outage history.
  2. Inspect intertier dependencies, RTO/RPO, test scripts and business sign-off criteria.
  3. Inspect ticket retention configuration, attachment lifecycle and regulatory obligations.
  4. Review network routes, partner links, certificates and recovery site failover plans.

Explanation

Correct Answer

D:

Review network routes, partner links, certificates and recovery site failover plans. The governing principle is: Disaster recovery design must cover external connectivity and noncompute dependencies.

Incorrect Answers

A:

Inspect dependency maps, test coverage, change approvals and outage history. This would be relevant to a different issue such as: A routine database update causes outages because no dependency assessment included reporting services. In the present case, the most directly relevant audit step is: Review network routes, partner links, certificates and recovery site failover plans. The governing distinction is: Disaster recovery design must cover external connectivity and noncompute dependencies.

B:

Inspect intertier dependencies, RTO/RPO, test scripts and business sign-off criteria.

Question 792

An IS auditor evaluates this situation: Procurement selects the lowest-cost cloud vendor while ignoring prior security incidents and regulatory audit rights. Which audit principle MOST directly applies to this situation?

  1. Sourcing decisions should assess total risk and contractual fitness, not price alone.
  2. Governance must detect changes in external obligations and translate them into owned controls.
  3. Vendor exit planning is necessary to manage concentration and operational continuity risk.
  4. IT performance measures must reflect business-service outcomes and relevant dependencies.

Explanation

Correct Answer

A:

Sourcing decisions should assess total risk and contractual fitness, not price alone. The corresponding audit procedure is: Examine due diligence, control reports, incident history and mandatory obligations.

Incorrect Answers

B:

Governance must detect changes in external obligations and translate them into owned controls. This would be relevant to a different issue such as: A bank's compliance register still lists a superseded regulatory reporting deadline after a rule change. In the present case, the most directly relevant principle is: Sourcing decisions should assess total risk and contractual fitness, not price alone. The governing distinction is: Sourcing decisions should assess total risk and contractual fitness, not price alone.

C:

Vendor exit planning is necessary to manage concentration and operational continuity risk. This would be relevant to a different issue such as: A critical provider exits the market and the customer has no usable data export or transition rights. In the present case, the most directly relevant principle is: Sourcing decisions should assess total risk and contractual fitness, not price alone. The governing distinction is: Sourcing decisions should assess total risk and contractual fitness, not price alone.

D:

IT performance measures must reflect business-service outcomes and relevant dependencies. This would be relevant to a different issue such as: The IT dashboard shows 100 percent server uptime while customers report failed checkout transactions. In the present case, the most directly relevant principle is: Sourcing decisions should assess total risk and contractual fitness, not price alone. The governing distinction is: Sourcing decisions should assess total risk and contractual fitness, not price alone.

Question 793

An IS auditor evaluates this situation: An auditee disputes an audit exception by supplying a later control fix, then asks to erase the historical finding. Which audit principle MOST directly applies to this situation?

  1. Join multiplicity can distort counts and audit conclusions even when query syntax succeeds.
  2. Risk-based communication should prioritize material implications and provide traceable support.
  3. Risk-based audit planning is dynamic when business context and material exposures change.
  4. Remediation after the audit period does not retroactively prove the control operated during that period.

Explanation

Correct Answer

D:

Remediation after the audit period does not retroactively prove the control operated during that period. The corresponding audit procedure is: Separate audit-period evidence, remediation date and independent retest results.

Incorrect Answers

A:

Join multiplicity can distort counts and audit conclusions even when query syntax succeeds. This would be relevant to a different issue such as: An audit query joins employee and privilege tables but mistakenly duplicates rows for users with multiple roles. In the present case, the most directly relevant principle is: Remediation after the audit period does not retroactively prove the control operated during that period. The governing distinction is: Remediation after the audit period does not retroactively prove the control operated during that period.

B:

Risk-based communication should prioritize material implications and provide traceable support. This would be relevant to a different issue such as: A board report includes hundreds of raw test details but fails to distinguish enterprise-critical findings. In the present case, the most directly relevant principle is: Remediation after the audit period does not retroactively prove the control operated during that period. The governing distinction is: Remediation after the audit period does not retroactively prove the control operated during that period.

C:

Risk-based audit planning is dynamic when business context and material exposures change. This would be relevant to a different issue such as: A merger adds a regulated customer database after the audit plan was approved, but the plan is treated as unchangeable. In the present case, the most directly relevant principle is: Remediation after the audit period does not retroactively prove the control operated during that period. The governing distinction is: Remediation after the audit period does not retroactively prove the control operated during that period.

Question 794

An IS auditor is preparing recommendations after reviewing this situation: An internal auditor helped configure the privileged-access system now scheduled for an assurance review. Which recommendation would BEST address the identified weakness?

  1. Clarify the engagement type and issue only conclusions supported by the work actually performed.
  2. Report the historical exception with clear current remediation status and corroborated response.
  3. Have the audit director assign an independent reviewer and disclose the conflict to appropriate oversight.
  4. Escalate unresolved pressure through the chief audit executive and retain the supported finding.

Explanation

Correct Answer

C:

Have the audit director assign an independent reviewer and disclose the conflict to appropriate oversight. The relevant control principle is: Auditor objectivity is impaired by assessing one's own recent design work. A meaningful follow-up should establish: A reviewer uninvolved in the original configuration signs off on workpapers and the conflict disposition.

Incorrect Answers

A:

Clarify the engagement type and issue only conclusions supported by the work actually performed. 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 recommendation is: Have the audit director assign an independent reviewer and disclose the conflict to appropriate oversight.

Question 798

Before reaching an audit conclusion, consider: An internal portal outage follows certificate expiration despite an automated renewal job that reported success. Which evidence should the auditor review FIRST to evaluate this risk?

  1. Inspect trust-store settings, CRL/OCSP reachability, cache behavior and certificate status.
  2. Compare renewed certificate inventory, deployed endpoints, validity dates and chain health.
  3. Inspect reviewer role, HR roster, role descriptions and sample revocation outcomes.
  4. Inspect signed authorization, timing constraints, target list and emergency stop procedures.

Explanation

Correct Answer

B:

Compare renewed certificate inventory, deployed endpoints, validity dates and chain health. The governing principle is: PKI monitoring should validate deployed certificates and trust paths, not just job status.

Incorrect Answers

A:

Inspect trust-store settings, CRL/OCSP reachability, cache behavior and certificate status. This would be relevant to a different issue such as: A revoked supplier certificate remains trusted by an application because revocation checks are disabled. In the present case, the most directly relevant audit step is: Compare renewed certificate inventory, deployed endpoints, validity dates and chain health.
