Question 270

An IS auditor evaluates this situation: A database access audit receives a file containing only current active users although it must assess leavers over the last quarter. Which audit principle MOST directly applies to this situation?

  1. Sampling from an incomplete population invalidates the intended terminated-user control test.
  2. Audit quality programs should evaluate consistency, methodology and continuous improvement.
  3. Judgmentally selected favorable examples cannot support a population-wide effectiveness conclusion.
  4. Risk-based communication should prioritize material implications and provide traceable support.

Explanation

Correct Answer

A:

Sampling from an incomplete population invalidates the intended terminated-user control test. The corresponding audit procedure is: Reconcile HR departures and access history against the access extract's coverage dates.

Incorrect Answers

B:

Audit quality programs should evaluate consistency, methodology and continuous improvement. This would be relevant to a different issue such as: An audit team changes sampling procedures each quarter without documenting why results are no longer comparable. In the present case, the most directly relevant principle is: Sampling from an incomplete population invalidates the intended terminated-user control test. The governing distinction is: Sampling from an incomplete population invalidates the intended terminated-user control test.

C:

Judgmentally selected favorable examples cannot support a population-wide effectiveness conclusion. This would be relevant to a different issue such as: Management offers ten handpicked successful failover demonstrations as evidence that every critical service has tested recovery. In the present case, the most directly relevant principle is: Sampling from an incomplete population invalidates the intended terminated-user control test. The governing distinction is: Sampling from an incomplete population invalidates the intended terminated-user control test.

D:

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: Sampling from an incomplete population invalidates the intended terminated-user control test. The governing distinction is: Sampling from an incomplete population invalidates the intended terminated-user control test.

Question 271

An IS auditor evaluates this situation: A chief information officer asks the audit lead to remove a supported high-risk finding before it reaches the audit committee. Which audit principle MOST directly applies to this situation?

  1. Professional independence requires reporting supported risk conclusions despite management preferences.
  2. Quality monitoring should reveal overdue high-risk actions and escalation effectiveness.
  3. Perceived or actual conflicts undermine the credibility of objective audit judgment.
  4. Evidence integrity and independence are weakened when subjects can alter the only record.

Explanation

Correct Answer

A:

Professional independence requires reporting supported risk conclusions despite management preferences. The corresponding audit procedure is: Compare evidence, management comments and the proposed report changes with reporting standards.

Incorrect Answers

B:

Quality monitoring should reveal overdue high-risk actions and escalation effectiveness. This would be relevant to a different issue such as: Three departments repeatedly miss remediation dates but audit management reports closure rates without aging analysis. In the present case, the most directly relevant principle is: Professional independence requires reporting supported risk conclusions despite management preferences. The governing distinction is: Professional independence requires reporting supported risk conclusions despite management preferences.

C:

Perceived or actual conflicts undermine the credibility of objective audit judgment. This would be relevant to a different issue such as: An external contractor offers the auditor a valuable gift while a supplier compliance assessment is being finalized. In the present case, the most directly relevant principle is: Professional independence requires reporting supported risk conclusions despite management preferences. The governing distinction is: Professional independence requires reporting supported risk conclusions despite management preferences.

D:

Evidence integrity and independence are weakened when subjects can alter the only record. This would be relevant to a different issue such as: A vendor's audit log is editable by the same administrator whose changes are under investigation. In the present case, the most directly relevant principle is: Professional independence requires reporting supported risk conclusions despite management preferences. The governing distinction is: Professional independence requires reporting supported risk conclusions despite management preferences.

Question 272

Management reports that this issue has been corrected: A research team labels every file confidential, generating excessive DLP false positives and routine overrides. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. The report links each claimed outcome to reproducible evidence and approved scope.
  2. An unapproved image fails deployment while approved images retain evidence of origin.
  3. DLP alerts retain useful coverage while confirmed legitimate workflows have fewer unjustified blocks.
  4. Approved staff retrieve only necessary records and excessive exports are flagged or blocked.

Explanation

Correct Answer

C:

DLP alerts retain useful coverage while confirmed legitimate workflows have fewer unjustified blocks. It addresses data loss prevention. Underlying audit concern: Overbroad classification can undermine effective enforcement and incident response.

Incorrect Answers

A:

In the present case, the most directly relevant verification is: DLP alerts retain useful coverage while confirmed legitimate workflows have fewer unjustified blocks. The governing distinction is: Overbroad classification can undermine effective enforcement and incident response.

B:

An unapproved image fails deployment while approved images retain evidence of origin. This would be relevant to a different issue such as: A container orchestration platform admits unverified public images into a payment workload namespace. In the present case, the most directly relevant verification is: DLP alerts retain useful coverage while confirmed legitimate workflows have fewer unjustified blocks. The governing distinction is: Overbroad classification can undermine effective enforcement and incident response.

D:

Approved staff retrieve only necessary records and excessive exports are flagged or blocked. 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 verification is: DLP alerts retain useful coverage while confirmed legitimate workflows have fewer unjustified blocks. The governing distinction is: Overbroad classification can undermine effective enforcement and incident response.

Question 273

An IS auditor is preparing recommendations after reviewing this situation: An audit manager signs the report although a junior tester's exceptions have not received independent review. Which recommendation would BEST address the identified weakness?

  1. Rebuild the population including historical departures before selecting test items.
  2. Complete and document supervisory review before finalizing the report.
  3. Recommend named ownership, response thresholds and tracked escalation for material alerts.
  4. Obtain documented authorization for the scope adjustment and rebaseline the plan.

Explanation

Correct Answer

B:

Complete and document supervisory review before finalizing the report. The relevant control principle is: Quality supervision requires sufficient review before relying on engagement conclusions. A meaningful follow-up should establish: Each finding links to reviewed evidence and all material open review notes are resolved.

Incorrect Answers

A:

Rebuild the population including historical departures before selecting test items. This would be relevant to a different issue such as: A database access audit receives a file containing only current active users although it must assess leavers over the last quarter. In the present case, the most directly relevant recommendation is: Complete and document supervisory review before finalizing the report. The governing distinction is: Quality supervision requires sufficient review before relying on engagement conclusions.

C:

Recommend named ownership, response thresholds and tracked escalation for material alerts.

In the present case, the most directly relevant recommendation is: Complete and document supervisory review before finalizing the report. The governing distinction is: Quality supervision requires sufficient review before relying on engagement conclusions.

Question 274

An IS auditor evaluates this situation: An auditor samples only Monday transactions to conclude that weekend payments were controlled effectively. Which audit principle MOST directly applies to this situation?

  1. A detective control must include timely response and accountability to reduce exposure.
  2. Analytics-assisted findings still require understandable criteria and independent validation.
  3. Judgmentally selected favorable examples cannot support a population-wide effectiveness conclusion.
  4. A nonrepresentative selection can lead to unsupported conclusions about the entire population.

Explanation

Correct Answer

D:

A nonrepresentative selection can lead to unsupported conclusions about the entire population. The corresponding audit procedure is: Reconcile the full transaction population by day, channel and risk characteristics.

Incorrect Answers

A:

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: A nonrepresentative selection can lead to unsupported conclusions about the entire population. The governing distinction is: A nonrepresentative selection can lead to unsupported conclusions about the entire population.

B:

Analytics-assisted findings still require understandable criteria and independent validation. This would be relevant to a different issue such as: An anomaly model ranks high-value payments as suspicious but the auditor cannot explain its scoring or false-positive rate. In the present case, the most directly relevant principle is: A nonrepresentative selection can lead to unsupported conclusions about the entire population. The governing distinction is: A nonrepresentative selection can lead to unsupported conclusions about the entire population.

C:

Judgmentally selected favorable examples cannot support a population-wide effectiveness conclusion. This would be relevant to a different issue such as: Management offers ten handpicked successful failover demonstrations as evidence that every critical service has tested recovery.

The governing distinction is: A nonrepresentative selection can lead to unsupported conclusions about the entire population.

Question 275

Management reports that this issue has been corrected: A server room uses badge access but an unattended emergency door allows unrecorded entry. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. A controlled upstream power loss leaves essential services within continuity targets.
  2. The application rejects a known revoked test certificate while accepting valid trusted peers.
  3. An authorized test shows alarms and personnel response without preventing emergency egress.
  4. All in-scope devices either report healthy protection or have approved tracked exceptions.

Explanation

Correct Answer

C:

An authorized test shows alarms and personnel response without preventing emergency egress. It addresses physical and environmental controls. Underlying audit concern: Physical access controls must cover alternate entry points and generate reliable access evidence.

Incorrect Answers

A:

A controlled upstream power loss leaves essential services within continuity targets. This would be relevant to a different issue such as: A data center's redundant power feeds terminate at the same upstream distribution panel. In the present case, the most directly relevant verification is: An authorized test shows alarms and personnel response without preventing emergency egress. The governing distinction is: Physical access controls must cover alternate entry points and generate reliable access evidence.

Question 277

An IS auditor evaluates this situation: A service desk deletes incident attachments when tickets are closed, preventing later regulatory review. Which audit principle MOST directly applies to this situation?

  1. Availability analysis must include upstream shared dependencies, not just redundant hosts.
  2. Incident evidence retention should match legal, audit and operational requirements.
  3. Incident closure should confirm restoration of the affected business service, not just infrastructure state.
  4. Log retention should align with business, legal, incident and privacy requirements.

Explanation

Correct Answer

B:

Incident evidence retention should match legal, audit and operational requirements. The corresponding audit procedure is: Inspect ticket retention configuration, attachment lifecycle and regulatory obligations.

Incorrect Answers

A:

Availability analysis must include upstream shared dependencies, not just redundant hosts. 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 principle is: Incident evidence retention should match legal, audit and operational requirements. The governing distinction is: Incident evidence retention should match legal, audit and operational requirements.

C:

Incident closure should confirm restoration of the affected business service, not just infrastructure state. This would be relevant to a different issue such as: Operations declares an incident resolved because a server restarted, although business transactions remain stuck. In the present case, the most directly relevant principle is: Incident evidence retention should match legal, audit and operational requirements. The governing distinction is: Incident evidence retention should match legal, audit and operational requirements.

D:

Log retention should align with business, legal, incident and privacy requirements. This would be relevant to a different issue such as: A financial application retains operational logs for only a week although investigation rules require six months. In the present case, the most directly relevant principle is: Incident evidence retention should match legal, audit and operational requirements. The governing distinction is: Incident evidence retention should match legal, audit and operational requirements.

Question 278

An IS auditor is preparing recommendations after reviewing this situation: An audit query joins employee and privilege tables but mistakenly duplicates rows for users with multiple roles. Which recommendation would BEST address the identified weakness?

  1. Correct the query's grain and validate exceptions against original records.
  2. Perform a documented plan refresh with the audit committee's appropriate approval.
  3. Escalate persistently overdue material findings and improve risk-weighted follow-up reporting.
  4. Repair the approved monitoring feed and add completeness checks before reliance.

Explanation

Correct Answer

A:

Correct the query's grain and validate exceptions against original records. The relevant control principle is: Join multiplicity can distort counts and audit conclusions even when query syntax succeeds. A meaningful follow-up should establish: Aggregate user counts and sampled privilege mappings agree with the source systems.

Incorrect Answers

B:

Perform a documented plan refresh with the audit committee's appropriate approval. 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 recommendation is: Correct the query's grain and validate exceptions against original records. The governing distinction is: Join multiplicity can distort counts and audit conclusions even when query syntax succeeds.

C:

Escalate persistently overdue material findings and improve risk-weighted follow-up reporting. This would be relevant to a different issue such as: Three departments repeatedly miss remediation dates but audit management reports closure rates without aging analysis. In the present case, the most directly relevant recommendation is: Correct the query's grain and validate exceptions against original records. The governing distinction is: Join multiplicity can distort counts and audit conclusions even when query syntax succeeds.

D:

Repair the approved monitoring feed and add completeness checks before reliance. This would be relevant to a different issue such as: A continuous monitoring dashboard reports zero failed access attempts because its collection job stopped three days ago. In the present case, the most directly relevant recommendation is: Correct the query's grain and validate exceptions against original records. The governing distinction is: Join multiplicity can distort counts and audit conclusions even when query syntax succeeds.

Question 279

An IS auditor is preparing recommendations after reviewing this situation: A legacy security standard remains mandatory even though new approved cloud services cannot technically meet it. Which recommendation would BEST address the identified weakness?

  1. Harmonize procedures or formally approve justified exceptions with assigned owners.
  2. Recommend a formally assessed update or compensating control with time-bound approval.
  3. Recommend a jurisdiction-specific obligation register and tested control mapping for the service.
  4. Recommend governed capacity reallocation or documented justification for new procurement.

Explanation

Correct Answer

B:

Recommend a formally assessed update or compensating control with time-bound approval. The relevant control principle is: Standards must be reviewed and changed through formal governance without silently weakening policy. A meaningful follow-up should establish: Affected cloud deployments follow a documented approved standard or valid exception.

Incorrect Answers

A:

Harmonize procedures or formally approve justified exceptions with assigned owners. This would be relevant to a different issue such as: Regional IT teams follow conflicting change-control procedures even though one enterprise policy applies. In the present case, the most directly relevant recommendation is: Recommend a formally assessed update or compensating control with time-bound approval. The governing distinction is: Standards must be reviewed and changed through formal governance without silently weakening policy.

C:

Recommend a jurisdiction-specific obligation register and tested control mapping for the service. This would be relevant to a different issue such as: A multinational cloud project assumes a control compliant in one country automatically satisfies every jurisdiction in which data is processed. In the present case, the most directly relevant recommendation is: Recommend a formally assessed update or compensating control with time-bound approval. The governing distinction is: Standards must be reviewed and changed through formal governance without silently weakening policy.

D:

Recommend governed capacity reallocation or documented justification for new procurement. 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 recommendation is: Recommend a formally assessed update or compensating control with time-bound approval. The governing distinction is: Standards must be reviewed and changed through formal governance without silently weakening policy.

Question 280

Management reports that this issue has been corrected: A sales team stores client contracts in an unapproved personal file-sharing account for convenience. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Confidential contracts reside only in approved managed repositories with appropriate access.
  2. Each retired device reconciles to approved erasure or destruction evidence and authorized release.
  3. Unauthorized formula changes are detected and regulatory calculations reconcile.
  4. Unauthorized script edits are denied and authorized revisions are traceable.

Explanation

Correct Answer
