Question 597:

  • Correct answer: D. Inaccuracy of financial reporting

  • Why: A flaw in the mapping between the front-end subledger and the main ledger can cause transactions to be recorded in wrong GL accounts. This distorts balances and the financial statements, which is the primary risk and the most serious consequence.

  • Why other options are less critical:
- Double-posting of a single journal entry: more a posting/control issue; mapping flaws could contribute, but it’s not the core risk. - Unauthorized alteration of account attributes: a security/access concern, not the direct impact of mapping accuracy. - Inability to support new business transactions: a functional/narrow capability issue, secondary to the broader risk of misstatement.
  • Key controls to mitigate:
- Regular reconciliation between subledger and GL. - Maintain and review the account-mapping table; change management for mappings. - Audit trails and automated validation checks to catch mismatches.

Question 589:

  • Correct answer: D
  • Why: For a unit handling intellectual property and patents, the ability for employees to share files with external users creates the highest risk of unauthorized disclosure or IP leakage. External sharing directly threatens confidentiality of sensitive IP.

  • Other options (less critical in this context):
- Training not provided (A) is important but indirect to IP leakage. - Logging for content filtering not enabled (B) is a broader security risk, but not as immediate as external sharing for IP. - Collaboration tool hosted and browser-only access (C) affects attack surface but doesn’t specifically address IP leakage through external sharing.
  • Suggested actions for the auditor:
- Verify external-sharing policies and enforcement. - Ensure Data Loss Prevention (DLP), access controls, and encryption for data in transit. - Confirm logging/audit trails and review least-privilege for sharing capabilities. - Provide targeted training on IP data handling if gaps exist.

Question 571:

  • Correct answer: D) Loss of application support

  • Why: Patches that are not tested before production violate change management and patch management policies. Many vendors require patches to be tested in a controlled environment and approved before deployment; if patches are deployed untested, the organization may no longer receive vendor support for issues related to those patches, increasing risk and response time during incidents.

  • Why the other options are less significant:
- A) Outdated documentation is a governance issue but not as directly tied to the risk of untested patches breaking support. - B) Developer access to production is a control weakness, but the key risk from untested patches is the potential loss of vendor support and increased downtime. - C) Lack of system integrity is a real risk, but loss of application support has wider operational and financial consequences when untested patches are involved.
  • Quick mitigation: enforce strict change control, require testing in a staging environment, implement rollback procedures, and ensure alignment with vendor support terms for patched components.

Question 566:

  • Correct answer: B — balanced scorecard.

  • Why: The metrics cover multiple perspectives used in a balanced scorecard approach:
- Financial: cost-revenue ratio - Customer: user satisfaction - Internal processes: computer downtime Together, they evaluate performance across key strategic areas, not just a single metric.
  • Why other options aren’t best:
- CSA: self-assessment of controls, not a broad performance dashboard. - Value chain analysis: focuses on value activities, not overall performance metrics. - Risk control framework: concentrates on risk governance and controls, not general performance measurement.
  • Key concept: A balanced scorecard translates strategy into a mix of financial and non-financial measures to monitor performance and align actions with goals.

Question 567:

  • Correct answer: D — developed by process owners.

Why: After confirming there is a quality security policy, the most important next step is to establish who owns and is accountable for the policy. If the policy is not developed by the process owners (the people responsible for the processes it governs), it may be impractical, unenforceable, or out of sync with actual operations. Ownership ensures alignment with business processes, accountability, and effective implementation and review.
Why the other options are less critical as the next step:
  • based on industry standards: Helpful for best practices but not sufficient alone; standards may not fit the organization's specifics.
  • well understood by all employees: Important for compliance, but only after proper ownership and governance mechanisms are in place.
  • updated frequently: Currency is important, but without owners responsible for updates, this often fails.

Key concept: policy ownership by process owners ensures governance, accountability, and alignment with actual operations.

Question 532:

  • Correct answer: C. Regular backups are made and stored offsite

  • Why this is the most important: The primary goal of a disaster recovery plan is to enable data and operations recovery after a disaster. If backups are not made regularly or are not stored offsite, a disaster could corrupt or destroy both the original data and any local backups, leaving the organization unable to restore critical systems. Offsite storage protects against site-specific risks (fire, flood, theft, etc.) and ensures data can be restored.

  • Why the other options are less critical for recovery capability:
- DRP updated regularly: important for accuracy, but without usable backups, recovery isn’t possible. - Roles and responsibilities documented: governance and accountability, not directly restoring data. - Tabletop DR tests: helps preparedness, but may not verify actual data restoration.
  • Audit steps you’d perform: verify backup schedules and frequency, confirm offsite storage and protection, review backup restoration testing and success rates, and ensure retention periods align with business needs.

Question 518:
Answer: B
Why: Data analytics in testing uses actual data to verify controls. By reviewing new account applications from the past month for invalid dates of birth, you analyze real patterns and exceptions, confirming whether the DOB validation is effective and where gaps may exist. This approach leverages data to facilitate testing.
Why the other options are less appropriate:

  • A: Reviewing the business requirements for the DOB field helps design tests but doesn’t use data analytics to test the process.
  • C: Attempting to submit invalid DOBs is manual testing and doesn’t involve analyzing data to guide testing.
  • D: Evaluating configuration settings focuses on setup, not on data-driven testing results.

Practical application:
  • Pull the last month of new account applications.
  • Identify records with invalid DOBs per the rules.
  • Analyze frequency, root causes, and impact to refine test cases and validation rules.

Question 513:

  • Correct answer: B — Mirrored sites

Why: For a low RTO (recovery time objective) and a low RPO (recovery point objective), you need near-instant failover and minimal data loss. Mirrored sites imply real-time or near real-time replication to a secondary site and automatic failover, which minimizes both downtime and data loss.
Option analysis:
  • Redundant arrays: protects against disk failures but not site-wide outages or rapid failover between sites.
  • Nightly backups: results in high RPO (up to 24 hours) and longer RTO.
  • Remote backups: protects against site loss but may involve network latency and not real-time failover; still higher RPO/RTO than true mirroring.

In short, mirrored sites provide the fastest recovery with the least data loss, matching the requirement for both low RTO and low RPO.

Question 467:

  • The correct answer is C: It acts as a measuring tool and progress indicator.

Why:
  • A maturity model provides defined levels to quantify current capability, baseline gaps, and track improvements over time.
  • This measurement and progressReporting support management decisions and visibility into how the organization is advancing.

Why the other options are less primary:
  • A: Identifying weaknesses is part of the assessment, but the primary value is the measurement framework, not just fixing gaps.
  • B: Facilitating an improvement plan can result from the assessment, but it’s a consequence, not the core benefit.
  • D: Ensuring organizational consistency and improvement is a broader outcome; the core, defining benefit is the measurement of maturity and progress.

Tip: Use the defined maturity levels to benchmark current state, set target levels, and perform periodic reassessments to demonstrate progress.

Question 466:

  • The correct answer is C: System downtime reports.

Why:
  • SLAs specify required availability. Downtime reports provide actual outages, durations, and times, which let you verify if uptime targets were met and identify any breaches.
  • These reports enable calculation of SLA metrics (e.g., uptime percentage, MTTR) and help correlate outages with maintenance windows or incidents.

Why the other options are less direct:
  • System utilization reports show usage patterns, not whether service levels were met.
  • Capacity planning tools help foresee demand but don’t confirm actual SLA performance.
  • IS strategic plan is high-level and not evidence of current SLA compliance.

Tip: Ensure downtime reports cover the period, affected services, outage cause, and whether outages were planned vs unplanned.
