Question 260

An IS auditor is preparing recommendations after reviewing this situation: A department builds a low-code workflow that sends customer data to an unknown external connector. Which recommendation would BEST address the identified weakness?

  1. Recommend independent protected backup custody and tested clean restoration.
  2. Recommend an EUC registry, approved connectors and security review before production use.
  3. Recommend sanctioned collaboration or compensating controls and managed migration.
  4. Recommend business-service indicators and contractual accountability for meaningful failures.

Explanation

Correct Answer

B:

Recommend an EUC registry, approved connectors and security review before production use. The relevant control principle is: Citizen-developed systems remain subject to data governance and integration security. A meaningful follow-up should establish: Only authorized destinations receive necessary data and workflow use is logged.

Incorrect Answers

A:

Recommend independent protected backup custody and tested clean restoration. This would be relevant to a different issue such as: An attacker encrypts production files and online backups because both use the same compromised admin identity. In the present case, the most directly relevant recommendation is: Recommend an EUC registry, approved connectors and security review before production use. The governing distinction is: Citizen-developed systems remain subject to data governance and integration security.

C:

Recommend sanctioned collaboration or compensating controls and managed migration. This would be relevant to a different issue such as: A sales team stores client contracts in an unapproved personal file-sharing account for convenience. In the present case, the most directly relevant recommendation is: Recommend an EUC registry, approved connectors and security review before production use. The governing distinction is: Citizen-developed systems remain subject to data governance and integration security.

D:

Recommend business-service indicators and contractual accountability for meaningful failures. This would be relevant to a different issue such as: A supplier SLA measures network interface uptime while the business requires successful customer transactions. In the present case, the most directly relevant recommendation is: Recommend an EUC registry, approved connectors and security review before production use. The governing distinction is: Citizen-developed systems remain subject to data governance and integration security.

Question 261

An IS auditor evaluates this situation: A major cyber outage is escalated only after normal helpdesk response times expire. Which audit principle MOST directly applies to this situation?

  1. Infrastructure health alone does not represent availability of external service dependencies.
  2. Severe incidents require priority-based classification and timely escalation paths.
  3. Incident evidence retention should match legal, audit and operational requirements.
  4. Continuity plans must integrate people, facilities, technology and business processes.

Explanation

Correct Answer

B:

Severe incidents require priority-based classification and timely escalation paths. The corresponding audit procedure is: Compare severity criteria, initial alerts, notification times and response records.

Incorrect Answers

A:

Infrastructure health alone does not represent availability of external service dependencies. This would be relevant to a different issue such as: A cloud-hosted application has healthy virtual machines but customer logins fail when its external identity service is unavailable. In the present case, the most directly relevant principle is: Severe incidents require priority-based classification and timely escalation paths. The governing distinction is: Severe incidents require priority-based classification and timely escalation paths.

C:

Incident evidence retention should match legal, audit and operational requirements. This would be relevant to a different issue such as: A service desk deletes incident attachments when tickets are closed, preventing later regulatory review. In the present case, the most directly relevant principle is: Severe incidents require priority-based classification and timely escalation paths. The governing distinction is: Severe incidents require priority-based classification and timely escalation paths.

D:

Continuity plans must integrate people, facilities, technology and business processes. This would be relevant to a different issue such as: A call center continuity binder lists alternate desks but employees cannot access the customer service application from that location. In the present case, the most directly relevant principle is: Severe incidents require priority-based classification and timely escalation paths. The governing distinction is: Severe incidents require priority-based classification and timely escalation paths.

Question 262

Management reports that this issue has been corrected: A certificate authority's signing key is available to several administrators without dual control. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Untrusted office endpoints cannot administer sensors and default passwords no longer work.
  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. An unauthorized administrator cannot export or use the CA signing key.

Explanation

Correct Answer

D:

An unauthorized administrator cannot export or use the CA signing key. It addresses public key infrastructure. Underlying audit concern: CA private keys require strong custody and accountable access due to their trust impact.

Incorrect Answers

A:

Untrusted office endpoints cannot administer sensors and default passwords no longer work. This would be relevant to a different issue such as: Warehouse sensors retain factory passwords and are reachable from the corporate office LAN. In the present case, the most directly relevant verification is: An unauthorized administrator cannot export or use the CA signing key. The governing distinction is: CA private keys require strong custody and accountable access due to their trust impact.

B:

The application rejects a known revoked test certificate while accepting valid trusted peers. 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 verification is: An unauthorized administrator cannot export or use the CA signing key. The governing distinction is: CA private keys require strong custody and accountable access due to their trust impact.

C:

An authorized test shows alarms and personnel response without preventing emergency egress. This would be relevant to a different issue such as: A server room uses badge access but an unattended emergency door allows unrecorded entry. In the present case, the most directly relevant verification is: An unauthorized administrator cannot export or use the CA signing key. The governing distinction is: CA private keys require strong custody and accountable access due to their trust impact.

Question 263

Before reaching an audit conclusion, consider: Management reports 99.99% uptime by excluding unscheduled customer-impacting outages from the metric. Which evidence should the auditor review FIRST to evaluate this risk?

  1. Group incident trends, known error records and evidence of shared failure conditions.
  2. Review nonfinancial impacts, dependency chains and stakeholder severity scales.
  3. Review rack placement, power/cooling diagrams, recovery design and fault dependencies.
  4. Compare raw downtime events, contract definitions and reporting transformations.

Explanation

Correct Answer

D:

Compare raw downtime events, contract definitions and reporting transformations. The governing principle is: Availability calculations require consistently defined scope, denominator and exclusions.

Incorrect Answers

A:

Group incident trends, known error records and evidence of shared failure conditions. This would be relevant to a different issue such as: A helpdesk repeatedly reopens application errors but closes each ticket without investigating a shared underlying defect. In the present case, the most directly relevant audit step is: Compare raw downtime events, contract definitions and reporting transformations. The governing distinction is: Availability calculations require consistently defined scope, denominator and exclusions.

B:

Review nonfinancial impacts, dependency chains and stakeholder severity scales. This would be relevant to a different issue such as: Continuity leadership bases recovery priorities on annual revenue only and ignores safety-critical low-volume services. In the present case, the most directly relevant audit step is: Compare raw downtime events, contract definitions and reporting transformations. The governing distinction is: Availability calculations require consistently defined scope, denominator and exclusions.

C:

Review rack placement, power/cooling diagrams, recovery design and fault dependencies. This would be relevant to a different issue such as: A database is replicated across two racks but both racks depend on the same cooling circuit. In the present case, the most directly relevant audit step is: Compare raw downtime events, contract definitions and reporting transformations. The governing distinction is: Availability calculations require consistently defined scope, denominator and exclusions.

Question 264

An IS auditor is preparing recommendations after reviewing this situation: A monitoring alert is generated for suspicious transfers, but no owner is assigned to investigate or close it. Which recommendation would BEST address the identified weakness?

  1. Recommend named ownership, response thresholds and tracked escalation for material alerts.
  2. Recommend distinct authenticated approvers and enforced separation of duties.
  3. Communicate the verified urgent exposure immediately to authorized management and audit leadership.
  4. Require qualified review separate from preparation for material testing and report conclusions.

Explanation

Correct Answer

A:

Recommend named ownership, response thresholds and tracked escalation for material alerts. The relevant control principle is: A detective control must include timely response and accountability to reduce exposure. A meaningful follow-up should establish: Sample alerts have timely decisions, documented resolution and escalation when overdue.

Incorrect Answers

B:

Recommend distinct authenticated approvers and enforced separation of duties. This would be relevant to a different issue such as: A new security control requires two operators to approve destructive data deletion, but both approvals can use one shared account. In the present case, the most directly relevant recommendation is: Recommend named ownership, response thresholds and tracked escalation for material alerts. The governing distinction is: A detective control must include timely response and accountability to reduce exposure.

C:

Communicate the verified urgent exposure immediately to authorized management and audit leadership. This would be relevant to a different issue such as: An auditor discovers an urgent uncontained data disclosure but plans to mention it only in the quarterly report. In the present case, the most directly relevant recommendation is: Recommend named ownership, response thresholds and tracked escalation for material alerts. The governing distinction is: A detective control must include timely response and accountability to reduce exposure.

D:

Require qualified review separate from preparation for material testing and report conclusions. This would be relevant to a different issue such as: An audit director relies on peer sign-offs that were completed by the same person who prepared each working paper. In the present case, the most directly relevant recommendation is: Recommend named ownership, response thresholds and tracked escalation for material alerts. The governing distinction is: A detective control must include timely response and accountability to reduce exposure.

Question 265

Management reports that this issue has been corrected: A production database account has unrestricted privileges for a read-only reporting integration. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. A site-loss simulation processes representative payments through the recovery location.
  2. The integration reads required views but cannot modify protected tables.
  3. Full valid descriptions survive transfer and oversized payloads generate tracked exceptions.
  4. An anticipated high-load period does not exhaust storage and restore capability remains intact.

Explanation

Correct Answer

B:

The integration reads required views but cannot modify protected tables. It addresses database management. Underlying audit concern: Database least privilege should restrict access by actual application function.

Incorrect Answers

A:

A site-loss simulation processes representative payments through the recovery location. 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 verification is: The integration reads required views but cannot modify protected tables. The governing distinction is: Database least privilege should restrict access by actual application function.

C:

Full valid descriptions survive transfer and oversized payloads generate tracked exceptions. This would be relevant to a different issue such as: An inventory API responds successfully while silently truncating long product descriptions during integration. In the present case, the most directly relevant verification is: The integration reads required views but cannot modify protected tables. The governing distinction is: Database least privilege should restrict access by actual application function.

D:

An anticipated high-load period does not exhaust storage and restore capability remains intact. This would be relevant to a different issue such as: Database transaction logs fill the only disk volume and cause a payment service outage. In the present case, the most directly relevant verification is: The integration reads required views but cannot modify protected tables. The governing distinction is: Database least privilege should restrict access by actual application function.

Question 266

Management reports that this issue has been corrected: A marketing platform collects customer location data without a documented lawful purpose or retention period. Which result would provide the STRONGEST assurance that the issue is corrected?

  1. Each data flow and regulated activity maps to approved obligations and demonstrated controls.
  2. Verified storage locations and downstream contracts align with permitted processing.
  3. Records demonstrate approved legal basis, limited fields and enforced deletion schedules.
  4. Sample requests locate applicable systems and receive complete timely disposition.

Explanation

Correct Answer

C:

Records demonstrate approved legal basis, limited fields and enforced deletion schedules. It addresses privacy program and principles. Underlying audit concern: Privacy governance should enforce purpose limitation, data minimization and accountable use.

Incorrect Answers

A:

Each data flow and regulated activity maps to approved obligations and demonstrated controls. 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 verification is: Records demonstrate approved legal basis, limited fields and enforced deletion schedules.

B:

Verified storage locations and downstream contracts align with permitted processing. 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 verification is: Records demonstrate approved legal basis, limited fields and enforced deletion schedules. The governing distinction is: Privacy governance should enforce purpose limitation, data minimization and accountable use.

D:

Sample requests locate applicable systems and receive complete timely disposition. This would be relevant to a different issue such as: An organization receives data subject requests but cannot locate personal records spread across cloud and on-premise systems. In the present case, the most directly relevant verification is: Records demonstrate approved legal basis, limited fields and enforced deletion schedules. The governing distinction is: Privacy governance should enforce purpose limitation, data minimization and accountable use.

Question 267

An IS auditor is preparing recommendations after reviewing this situation: An audit director relies on peer sign-offs that were completed by the same person who prepared each working paper. Which recommendation would BEST address the identified weakness?

  1. Escalate persistently overdue material findings and improve risk-weighted follow-up reporting.
  2. Clarify the engagement type and issue only conclusions supported by the work actually performed.
  3. Require qualified review separate from preparation for material testing and report conclusions.
  4. Resolve the conflicting accounts using contemporaneous authoritative records.

Explanation

Correct Answer

C:

Require qualified review separate from preparation for material testing and report conclusions. The relevant control principle is: Independent workpaper review is undermined by self-approval. A meaningful follow-up should establish: Workpapers demonstrate distinct preparer and reviewer approvals and resolved comments.

Incorrect Answers

A:

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: Require qualified review separate from preparation for material testing and report conclusions. The governing distinction is: Independent workpaper review is undermined by self-approval.

B:

Clarify the engagement type and issue only conclusions supported by the work actually performed.

  1. Recommend dependency register updates and tested risk-based failover procedures.
  2. Recommend independent communications paths or explicit mitigation for shared exposure.
  3. Recommend business-approved RPO and matching protection technology.
  4. Recommend independent failure domains or formally accepted residual exposure.

Explanation

Correct Answer

A:

Recommend dependency register updates and tested risk-based failover procedures. The relevant control principle is: Resilience planning must include external and supporting infrastructure dependencies. A meaningful follow-up should establish: A controlled DNS failure exercise meets continuity expectations or documents accepted gaps.

Incorrect Answers

B:

Recommend independent communications paths or explicit mitigation for shared exposure. This would be relevant to a different issue such as: Two data centers have separate buildings but share one telecom carrier and underground duct. In the present case, the most directly relevant recommendation is: Recommend dependency register updates and tested risk-based failover procedures. The governing distinction is: Resilience planning must include external and supporting infrastructure dependencies.

C:

Recommend business-approved RPO and matching protection technology. This would be relevant to a different issue such as: A sales system's backup schedule is chosen before the business determines acceptable data loss. In the present case, the most directly relevant recommendation is: Recommend dependency register updates and tested risk-based failover procedures. The governing distinction is: Resilience planning must include external and supporting infrastructure dependencies.

D:

Recommend independent failure domains or formally accepted residual exposure.
