Question 441:
Correct answer: C – Continuity of service

• VoIP is real-time and relies on network availability. If the network or power fails, voice communication stops, making continuity of service the highest priority risk from an IS auditor’s perspective.
• Other options: Nonrepudiation is less critical for VoIP; it’s hard to enforce for voice calls. Identity management is important but not the single most important issue. Homogeneity of the network is not essential for VoIP functioning.
• Auditor focus: ensure redundancy, failover capabilities, robust disaster recovery/plans for VoIP, QoS, and emergency call handling to maintain service during outages.

Question 439:
Question 439: Which of the following would be a result of utilizing a top-down maturity model process?

• Correct answer: D: A means of benchmarking the effectiveness of similar processes with peers.

• A top-down maturity model starts at the enterprise level, setting target maturity levels and then assessing processes against external benchmarks.
• This approach emphasizes comparing your processes to peers or industry standards (benchmarking), rather than just internal comparisons.
• By contrast, bottom-up approaches focus on identifying improvement opportunities within individual processes or finding gaps across processes internally.

Question 421:
Correct answer: D. The organization does not monitor upgrades to its software.
Explanation:

• Licensing compliance hinges on ongoing entitlement and usage tracking, including upgrades. If upgrades aren’t monitored, the organization may deploy newer versions or features without updating licenses, potentially violating terms or exceeding approved licenses.
• Option B describes a monthly license verification, which is a positive control and reduces risk. Option A (centralized server) can ease management, not heighten risk. Option C (desktop software expensed, not capitalized) relates more to asset capitalization than license compliance.
• Therefore, failing to monitor upgrades poses the greatest compliance risk during an audit.

Question 418:

• Correct answer: D. Code review

• Why: Verifying application program controls means checking that the software itself enforces the designed controls (e.g., input validation, authorization, processing integrity). A code review directly examines the program logic and control implementation to confirm these controls exist and are correctly applied.

• Why the others are less appropriate:

• Note: Code reviews are often complemented by testing and documentation, but for verifying program controls, code review is the most appropriate technique.

Question 401:
Answer: A. The integrity of data processed by end user tools.
Why this is correct:

• EUC tools (like spreadsheets) often bypass centralized change controls. If the data they produce is unreliable, any conclusions or reports from those tools can be false, regardless of other controls.
• When planning an EUC assessment, the auditor focuses on data quality, accuracy, completeness, and traceability of inputs/outputs from end-user tools.

• Inclusion of end user tools in the IT balanced scorecard: useful for governance visibility but doesn’t address the fundamental risk to data reliability.
• Identification of IT owners for each end user tool: governance and accountability are important, but without data integrity, ownership alone offers limited assurance.
• Training program curriculum for key end users: important for capability, but data integrity issues exist regardless of training.

• Inventory critical EUC tools and data flows.
• Assess data sources, input validation, formulas, and reconciliation with trusted data.
• Review version control, change management, and access controls for EUC tools.

Question 392:

• Correct answer: D – Examine project change request logs

• Why: A post-implementation review (PIR) assesses ongoing governance and how changes are managed after go-live. Examining change request logs verifies that changes to the application are properly documented, authorized, tracked, and aligned with policy. It also helps assess the effectiveness of change control, including back-outs and impact analysis.

• Why the other options are less appropriate for PIR:

• Audit tips: sample change entries, verify approvals, check for adherence to the change management process, review emergency changes, and ensure there’s evidence of testing and rollback plans.

Question 356:

• Answer: B Understanding the data classification levels

• Explanation: In a data classification program, the first and most critical step is defining the classification levels and the criteria for each level. This framework drives which controls, labeling, access, retention, and protection measures apply to data. Without clear levels, planning (storage), ownership roles, and privacy policy cannot be effectively aligned to risk and regulatory requirements. The other options are important but depend on having established classification levels.

Question 312:

• Correct answer: Post-implementation review phase.

• Why: Benefits realization analysis assesses whether the project actually delivered the expected business value after it is implemented and in operation. This phase uses real metrics (KPIs, ROI, cost savings, user adoption) to compare actual results against the business case and baseline.

• Why not other phases:

• What to do in post-implementation:

• ISACA relevance: aligns with governance and value delivery, ensuring the IT investment actually delivers planned benefits.

Question 302:

• Correct answer: C — based on the results of an organization-wide risk assessment.

• Data classification standards should reflect the organization’s risk landscape. A risk assessment identifies which information assets are most sensitive or critical and the potential impact if they are compromised.
• This ensures classification levels (e.g., public, internal, confidential) align with actual risk, not just subjective notions of confidentiality or other single factors.

• A: Focusing only on confidentiality ignores impacts on integrity and availability and may misclassify data.
• B: Segregation of duties relates to roles/access control, not how data should be classified.
• D: Authentication requirements pertain to user identity controls, not the data’s classification framework.

Question 293:

• Correct answer: C. Evidence of population completeness is not maintained.

• A: Sampling only from the current period can introduce bias, but it’s a narrower issue than lacking population completeness.
• B: Removing auditor judgment is a concern, but automation can be designed with safeguards; it’s not the single greatest risk here.
• D: Manual validation before loading data adds effort but doesn’t inherently threaten the validity of the sampling frame itself.
