IIA-CIA-Part3 IIA Business Knowledge for Internal Auditing Free Practice Exam Questions (2025 Updated)

To assess the success of a piloted data analytics model in identifying anomalies in vendor payments and potential fraud, the most appropriate criterion is the accuracy of the model in identifying true positives—cases flagged as anomalies that were later confirmed as valid fraud risks.

Effectiveness of the Model: The primary goal of the model is to enhance the internal audit activity’s ability to detect fraudulent transactions. The best way to measure success is to analyze how many flagged transactions were confirmed as fraudulent or erroneous.

Reduction of False Positives and False Negatives: A model that generates too many false positives (incorrectly flagged transactions) can lead to inefficiencies, while too many false negatives (missed fraudulent cases) can reduce the effectiveness of fraud detection.

Alignment with Internal Audit Standards: According to IIA Standard 1220 - Due Professional Care, internal auditors must apply appropriate tools and techniques (such as data analytics) to enhance audit effectiveness. The model's success should be assessed based on its ability to provide reliable, actionable insights.

IIA Practice Guide on Data Analytics: Recommends assessing the predictive accuracy of models by comparing flagged transactions against actual outcomes.

B. The development and maintenance costs associated with the model (Incorrect)

While cost is a consideration, it does not directly assess the effectiveness of the model in detecting fraud.

High costs may indicate inefficiency, but they do not determine whether the model is accurately identifying fraudulent transactions.

IIA Standard 2100 - Nature of Work emphasizes that internal audit activities must contribute to the improvement of governance, risk management, and control, which requires a focus on results rather than just cost.

C. The feedback of auditors involved with developing the model (Incorrect)

Feedback is useful but subjective. The ultimate test of success is not auditor perception but whether the model correctly identifies fraudulent or anomalous transactions.

IIA Practice Guide: Auditing Data Analytics suggests that while stakeholder feedback is valuable, empirical validation (accuracy of flagged cases) should be the primary success measure.

D. The number of criminal investigations initiated based on the outcomes of the model (Incorrect)

While fraud detection can lead to investigations, the number of investigations is not necessarily an accurate measure of model success.

Some flagged cases may not lead to criminal investigations due to materiality, lack of sufficient evidence, or management decisions.

According to IIA Standard 2120 - Risk Management, internal auditors must evaluate fraud risk management effectiveness, which includes detecting and preventing fraud, not just the legal consequences.

Explanation of Answer Choice A (Correct Answer):Explanation of Incorrect Answers:Conclusion:The best success criterion for the piloted data analytics model is the percentage of cases flagged by the model and confirmed as positives (Option A), as it directly measures the model's effectiveness in detecting actual fraud cases.

Why is Indefinite Retention a Violation?Analysis of Incorrect Answers:IIA References:Thus, the correct answer is B. The organization retains customers' personal information indefinitely.

Performance Measurement Should Provide Meaningful Insights:

While providing detailed statistics on disbursements, the greatest concern is whether the data is relevant to achieving the objective of accurate disbursements.

If the data does not directly support decision-making or process improvements, it may not serve its intended purpose.

IIA Standard 2010 - Planning requires internal auditors to evaluate the relevance of information used in decision-making.

A. Articulation of the data (Incorrect)

The way the data is presented is important but is a secondary concern compared to whether the data is relevant.

B. Availability of the data (Incorrect)

While timely access to data is critical, the primary concern is whether the data is meaningful in evaluating disbursement accuracy.

C. Measurability of the data (Incorrect)

The data is already being measured and reported; the real issue is whether it provides useful insights for improving accuracy.

Explanation of Incorrect Answers:Conclusion:The greatest concern with this performance measurement is whether the data is relevant (Option D) to assessing disbursement accuracy and guiding improvements.

Preventing security breaches requires proactive security controls, and the approval of identity requests ensures that only authorized individuals gain access to systems and data.

Types of Security Controls:

Preventive Controls (Stop security incidents before they happen)

Detective Controls (Identify security breaches after they occur)

Corrective Controls (Address security issues after detection)

Why Identity Request Approval is the Most Effective Preventive Control?

User access approval ensures that only verified personnel receive credentials.

According to IIA GTAG on Identity and Access Management, user provisioning must follow strict approval workflows to prevent unauthorized access.

By restricting access before a breach occurs, organizations reduce risks related to insider threats, phishing attacks, and credential misuse.

Why Not Other Options?

B. Access Logging:

Access logs record activity but do not prevent security breaches.

C. Monitoring Privileged Accounts:

Monitoring privileged accounts helps detect suspicious activity but does not stop unauthorized access beforehand.

D. Audit of Access Rights:

Regular audits ensure compliance but do not actively prevent unauthorized access in real-time.

Step-by-Step Justification:IIA References:Thus, the correct and verified answer is A. Approval of identity request.

Database backup methodologies ensure data protection and recovery in case of failures, system crashes, or cyber incidents. The most efficient method balances performance, storage, and recovery speed.

Incremental Backup on a Daily Basis (Correct Answer: D)

Incremental backups store only the changes made since the last backup.

This method saves storage space and reduces backup time, making it highly efficient for large production databases.

IIA Standard 2120 – Risk Management emphasizes that auditors must assess the efficiency and reliability of IT controls, including backup strategies.

This approach minimizes downtime and ensures the most recent data is available for recovery.

Why the Other Options Are Incorrect:

A. Disk Mirroring (Incorrect)

Disk mirroring (RAID 1) creates an exact real-time copy of data, but it is not a backup method—it only provides redundancy.

If corruption occurs in the database, the mirrored disk will also have corrupted data.

B. Weekly Differential Backup (Incorrect)

Differential backups store changes since the last full backup, but performing them only weekly means data loss could be significant if a failure occurs mid-week.

They consume more storage over time compared to incremental backups.

C. Independent Disk Array (Incorrect)

Redundant Arrays of Independent Disks (RAID) are primarily used for storage performance and fault tolerance, not as an efficient backup methodology.

RAID does not replace the need for incremental or full backups.

IIA Standard 2120 – Risk Management (Assessing IT controls, including backup and data recovery strategies)

IIA Standard 2110 – Governance (Ensuring IT risk management aligns with organizational objectives)

IIA Standard 2130 – Compliance (Verifying adherence to IT security and backup policies)

Step-by-Step Justification:IIA References for This Answer:Thus, the best answer is D. An incremental backup of the database on a daily basis, as it optimizes efficiency, reduces storage usage, and ensures up-to-date backups with minimal disruption.

A Wide Area Network (WAN) is the most suitable type of network for an organization that has operations in multiple cities and countries. WANs connect multiple local area networks (LANs) and other types of networks across long geographical distances, enabling seamless communication and data sharing among remote offices and branches.

A. Wide Area Network (WAN) (Correct Answer)

WANs cover extensive geographical areas, such as multiple cities, countries, or even continents.

They use various communication technologies, including leased lines, satellite connections, VPNs, and MPLS.

WANs enable organizations with distributed operations to centralize data management and enhance business continuity.

Example: An international corporation like a multinational bank or a global retail chain relies on a WAN to link its offices worldwide.

B. Local Area Network (LAN) (Incorrect Answer)

LANs are confined to a small area, such as an office building, factory, or campus.

They provide high-speed connectivity but are not designed for geographically dispersed locations.

Example: A single office using Ethernet and Wi-Fi to connect employees’ devices.

C. Metropolitan Area Network (MAN) (Incorrect Answer)

MANs span a city or a large campus but do not extend to multiple countries.

Example: A city's government agencies using a fiber-optic MAN for interdepartmental communication.

D. Storage Area Network (SAN) (Incorrect Answer)

SANs are dedicated high-speed networks designed for large-scale data storage and retrieval.

They are not meant for interconnecting geographically dispersed locations.

Example: A financial institution using a SAN for high-speed access to critical databases.

The IIA’s Global Technology Audit Guide (GTAG) – IT Risks and Controls emphasizes the importance of network infrastructure in securing and managing organizational data across multiple locations.

IIA Standard 2110 – Governance requires internal auditors to evaluate whether the organization’s IT strategy (including WAN infrastructure) supports business objectives and risk management.

Explanation of Answer Choices:IIA References:Thus, the correct answer is A. Wide Area Network (WAN).

A high-performance culture is one where employees are motivated to achieve excellence, innovate, and contribute to organizational success. This requires recognition of individual contributions, team collaboration, and strong leadership.

Let's analyze each option:

A. Reiterating the importance of compliance with established policies and procedures.

Incorrect. While compliance is crucial for governance and risk management, simply enforcing policies does not inherently promote high performance. High-performance cultures go beyond compliance to encourage innovation, creativity, and ownership.

B. Celebrating employees' individual excellence. ✅ (Correct Answer)

Correct. Recognizing and rewarding employees for their achievements, innovation, and outstanding performance fosters motivation, engagement, and a culture of continuous improvement.

Examples include employee recognition programs, awards, and performance-based incentives.

C. Periodically rotating operational managers.

Incorrect. While job rotation can provide exposure to different roles, frequent changes in leadership may disrupt continuity and stability, potentially harming long-term performance.

D. Avoiding status differences among employees.

Incorrect. While reducing hierarchical barriers can improve collaboration, completely eliminating status differences is unrealistic. A well-structured leadership framework helps set clear roles, expectations, and accountability.

IIA Standard 2110 – Governance – Encourages fostering a performance-driven culture.

COSO ERM Framework – Performance & Strategy Alignment – Discusses the role of motivation and recognition in achieving organizational goals.

Penetration testing is a security practice used to identify vulnerabilities in an organization's information systems by simulating cyberattacks. It is an essential component of IT risk management and internal auditing under The Institute of Internal Auditors (IIA) standards, particularly in the context of IT governance, cybersecurity risk management, and control assurance.

Focus on Preventive Controls:

Penetration testing evaluates how well preventive controls (e.g., firewalls, encryption, authentication mechanisms) work against potential cyberattacks.

According to the IIA Global Technology Audit Guide (GTAG) 11: Developing an IT Audit Plan, testing should emphasize preventive security measures to minimize risks.

Management’s Response Assessment:

The effectiveness of an organization's incident response plan is also evaluated.

Management's reaction to simulated cyber threats ensures that detection and response mechanisms are functional and aligned with IIA Standard 2120 – Risk Management and IIA GTAG 1: Information Security Governance.

A. Testing should not be announced to anyone within the organization to solicit a real-life response. (Incorrect)

Reason: While unannounced tests (e.g., red team exercises) can provide real-world insights, penetration testing should be coordinated with IT and security personnel.

IIA GTAG 11 emphasizes structured and ethical testing approaches, ensuring that necessary stakeholders are informed to prevent operational disruptions.

B. Testing should take place during heavy operational time periods to test system resilience. (Incorrect)

Reason: While resilience testing is important, penetration testing is typically performed in controlled conditions to avoid disrupting business operations.

IIA Standard 2130 – Control supports minimizing business risks during testing.

C. Testing should be wide in scope and primarily address detective management controls for identifying potential attacks. (Incorrect)

Reason: While detection controls (e.g., intrusion detection systems) are important, penetration testing focuses primarily on preventive controls.

IIA GTAG 1 and IIA GTAG 11 stress proactive security strategies over purely detective measures.

IIA Global Technology Audit Guide (GTAG) 11: Developing an IT Audit Plan – Covers IT security testing, including penetration testing.

IIA GTAG 1: Information Security Governance – Emphasizes the role of security assessments.

IIA Standard 2120 – Risk Management – Highlights the importance of testing preventive security measures.

IIA Standard 2130 – Control – Discusses ensuring operational effectiveness during testing.

Explanation of the Correct Answer (D):Analysis of Incorrect Answers:IIA References:Thus, D is the most accurate choice as per IIA guidance.

Comprehensive and Detailed In-Depth Explanation:

The tape rotation schedule is a method used to manage and organize backup media to ensure data is retained for the required period and can be restored when necessary. Different rotation schemes, such as Grandfather-Father-Son (GFS), determine how long each backup tape is kept before being overwritten, directly affecting data retention policies. While real-time backups (option A) provide continuous data protection, they are not always necessary or practical for all systems. Storing backups onsite (option B) offers quick access but may not protect against site-specific disasters; offsite storage is often recommended. Regular restoration tests (contrary to option D) are essential to ensure backup integrity and reliability, not just in failure scenarios.

Comprehensive and Detailed In-Depth Explanation:

Partnership contributions should be recorded at their fair market value (FMV) at the time of contribution, ensuring equitable financial representation.

Option A (Original cost of the equipment) – Not appropriate since the asset’s current fair value is relevant, not its historical cost.

Option B (Weighted average approach) – Not applicable; capital accounts should reflect actual contributed value.

Option C (No action necessary) – Incorrect because partners contributed assets of different values, making an equal capital credit unfair.

Since partnership accounting requires fair market value for capital accounts, Option D is correct.

Comprehensive and Detailed In-Depth Explanation:

Under the variable costing method, only costs that vary directly with production volume are treated as product costs. This includes direct labor costs (the wages of employees directly involved in manufacturing) and manufacturing supplies (materials consumed during production). Insurance on a factory is a fixed overhead cost, and packaging and shipping costs are typically considered period costs or selling expenses, as they are incurred after production. Therefore, options 1 and 3 correctly represent product costs under variable costing.
