Free Practice Questions for IIA IIA-CIA-Part3 Exam

Understanding Organizational Structures:

Organizations structure their workforce based on functions, products, or a combination of both.

A matrix organization combines functional and project-based structures, where employees report to both a functional manager and a project manager.

Why Option C (Matrix Organization) Is Correct?

The software development firm uses employees from multiple departments who report to a single project manager, which is a defining characteristic of a matrix structure.

Employees maintain their departmental roles while contributing to project-based work.

IIA Standard 2110 – Governance supports evaluating flexible organizational structures like matrix organizations to ensure accountability and risk management.

Why Other Options Are Incorrect?

Option A (Functional departmentalization):

In functional structures, employees report to one department head, not a project manager.

Option B (Product departmentalization):

In product-based structures, employees are grouped based on specific product lines, not cross-functional projects.

Option D (Divisional organization):

A divisional structure separates business units based on markets, regions, or customer segments, not cross-functional teams.

A matrix organization allows employees to work across departments under a project manager, making option C the best choice.

IIA Standard 2110 supports assessing governance structures that involve cross-functional teams.

Fraud in time-tracking systems—such as " buddy punching " (where one employee clocks in/out for another)—is a common payroll fraud scheme. The most effective method to prevent this is biometric authentication, which ensures that only the actual employee can clock in or out.

(A) Face or finger recognition equipment. ✅

Correct. Biometric authentication (such as fingerprint or facial recognition) is the most effective solution because it uniquely identifies each individual, making it impossible for an employee to clock in on behalf of a colleague.

IIA GTAG " Managing and Auditing IT Vulnerabilities " recommends biometric authentication as a strong fraud prevention measure.

IIA Practice Guide " Fraud Prevention and Detection in an Automated Environment " highlights the use of biometrics for enhancing security in access control systems.

(B) Radio-frequency identification (RFID) chips to authenticate employees with cards.

Incorrect. RFID cards can be shared between employees, allowing fraud to continue. They are useful for access control but do not verify the identity of the person using the card.

(C) A requirement to clock in and clock out with a unique personal identification number (PIN).

Incorrect. PINs can be shared or stolen, making them ineffective in preventing buddy punching.

(D) A combination of a smart card and a password to clock in and clock out.

Incorrect. Like RFID and PIN systems, smart cards and passwords can be shared, making them ineffective against fraudulent time-tracking practices.

IIA GTAG – " Managing and Auditing IT Vulnerabilities "

IIA Practice Guide – " Fraud Prevention and Detection in an Automated Environment "

COSO Framework – Fraud Risk Management

Analysis of Answer Choices:IIA References:Thus, the correct answer is A, as biometric authentication directly verifies the employee’s identity, preventing time-tracking fraud.

A targeted approach is used when internal audit performs a specific engagement focused directly on organizational culture, including culture-related processes, controls, risks, and indicators. This differs from an integrated approach, where culture considerations are embedded into multiple audits across the audit plan. A top-down approach would begin with senior leadership, governance, tone at the top, and strategic cultural expectations. A blended approach would combine direct culture audits with culture assessment within other engagements. In this question, the CAE scheduled an assurance engagement specifically on key processes and controls related to organizational culture, making it a focused or targeted engagement. Therefore, Option C is correct.

Integrity controls are application controls designed to monitor data being processed to ensure that it remains accurate, consistent, and valid throughout its lifecycle. These controls help detect and prevent data corruption, unauthorized modifications, and inconsistencies in transactional systems.

Integrity controls enforce data validation, consistency checks, and reconciliation procedures to prevent errors during processing.

Examples include checksum validation, referential integrity constraints, and automated reconciliations to ensure data accuracy.

The IIA’s Global Technology Audit Guide (GTAG) 8 – Auditing Application Controls highlights integrity controls as a key measure in maintaining data reliability.

A. Management trail controls → Incorrect. These refer to audit trails and logs that track changes and actions within a system but do not actively monitor or correct data integrity.

B. Output controls → Incorrect. These focus on ensuring final reports, documents, or processed data outputs are accurate but do not monitor data during processing.

D. Input controls → Incorrect. These verify the accuracy and completeness of data at the point of entry, but they do not continuously monitor data throughout processing.

IIA GTAG 8 – Auditing Application Controls recommends integrity controls to maintain data accuracy.

IIA Standard 2120 – Risk Management states that internal auditors should assess data integrity risks in business processes.

ISACA’s COBIT Framework identifies data integrity as a key IT control objective.

Why Option C is Correct?Explanation of the Other Options:IIA References & Best Practices:Thus, the correct answer is C. Integrity controls.

Planning (ERP) software implementation, to evaluate whether the organization is prepared for the change. This type of audit helps identify potential risks, resource availability, process gaps, and stakeholder alignment, which are critical for successful implementation.

A. Readiness assessment (Correct Answer) – This assessment evaluates if the organization has the necessary resources, technology, and processes in place for a successful ERP implementation.

B. Project risk assessment – While a project risk assessment identifies potential threats to project success, it does not provide an overall assurance on readiness before implementation.

C. Post-implementation review – This is conducted after the project is completed and does not help assess the likelihood of success before implementation.

D. Key phase review – This approach evaluates progress during implementation but does not provide enterprise-wide assurance before starting the project.

IIA GTAG 12 – Auditing IT Projects recommends a readiness assessment before launching major IT initiatives.

IIA IPPF Standard 2120 – Risk Management emphasizes identifying pre-implementation risks to improve project success.

COBIT 2019 – APO03 (Managed Enterprise Architecture) supports readiness evaluations before system rollouts.

Explanation of Each Option:IIA References:

The CAE’s first step when a project manager accepts a risk that appears significant is to discuss and communicate the risk with senior management. If management agrees with the project manager, and the CAE still considers the risk unacceptable, then it must be escalated to the board.

Option A (employee education) is outside audit’s role. Option B is premature—escalation to the board happens only if management does not resolve the issue. Option D is not within internal audit’s authority.

To prevent unauthorized wireless network access, the strongest control is to require access through a Virtual Private Network (VPN). A VPN encrypts data and ensures that only authorized users with proper credentials can connect securely.

Encryption & Secure Communication: VPNs use strong encryption protocols (e.g., AES-256) to protect data from unauthorized access.

Restricted Access Control: Users must authenticate through a secure VPN gateway, reducing the risk of unauthorized access.

Compliance with IT Security Standards: VPNs are recommended by security frameworks such as NIST 800-53, ISO 27001, and CIS Critical Security Controls.

Option B (Logging devices that access the network, including date, time, and user identity): Logging is important for monitoring but does not prevent unauthorized access—it only records it after the fact.

Option C (Tracking all mobile device physical locations and banning access from non-designated areas): Geofencing can help restrict access but is not as secure as a VPN, and attackers could spoof locations.

Option D (Permitting only authorized IT personnel to have administrative control of mobile devices): While restricting administrative control is good practice, it does not prevent unauthorized users from connecting to the network.

IIA’s GTAG on IT Security & Cybersecurity Risks highlights VPNs as a critical security measure to prevent unauthorized access.

ISO 27001 (Annex A.13) – Network Security Management recommends encrypting data transmissions to secure wireless network access.

NIST 800-53 (SC-12, SC-13, SC-28) emphasizes using VPNs for secure remote and wireless network access.

Why Option A is Correct (VPN):Why Other Options Are Incorrect:IIA References:Thus, the most appropriate answer is A. Allowing access to the organization ' s network only through a virtual private network (VPN).

Comprehensive and Detailed In-Depth Explanation:

Prioritizing the restoration of business systems requires input from multiple departments because different teams depend on various systems for operations.

Option A (Backup frequency) – Typically an IT decision, with minimal department-wide input.

Option C (Assigning IT personnel) – An internal IT function.

Option D (Assessing recovery resources) – Primarily handled by IT and finance, but restoration priorities require broader input.

Since business continuity planning involves multiple stakeholders, Option B is correct.

To test the accuracy of information already housed in a database on an un-networked computer, the auditor should select a sample of records and trace them to supporting documentation. This directly verifies whether stored database information is accurate, valid, and supported by source evidence. Submitting test transactions is more appropriate for testing system processing controls rather than validating existing database records. A test program simulating data entry also tests processing logic, not necessarily the accuracy of current data. Evaluating change management may be relevant to system integrity, but it does not directly prove that the data is accurate. Internal auditors should select the test approach that directly addresses the audit objective. Since the objective is data accuracy, Option C is correct.

Definition of Project Crashing:

Project crashing is a schedule compression technique used in project management to reduce the project completion time without changing its scope.

It involves adding extra resources (labor, equipment, budget) to critical path activities to complete them faster.

Key Aspects of Project Crashing:

Reduces project duration by increasing resources.

Leads to higher costs due to additional labor or expedited material procurement.

Used when project deadlines must be met and standard scheduling techniques are insufficient.

Why Other Options Are Incorrect:

A. It leads to an increase in risk and often results in rework:

While crashing can increase costs and risk, it does not necessarily result in rework unless poorly executed.

B. It is an optimization technique where activities are performed in parallel rather than sequentially:

This describes fast-tracking, not crashing. Fast-tracking involves overlapping tasks, while crashing adds resources to speed up tasks.

C. It involves a revaluation of project requirements and/or scope:

Crashing does not change project scope; it only shortens the schedule by allocating additional resources.

IIA’s Perspective on Project Risk and Management:

IIA Standard 2110 – Governance emphasizes the importance of project risk assessment, including schedule compression risks.

COSO ERM Framework identifies project cost overruns and resource misallocations as key risks in project execution.

PMBOK (Project Management Body of Knowledge) defines crashing as a schedule compression technique used when deadlines must be met at additional cost.

IIA References:

IIA Standard 2110 – Governance & Risk Oversight in Project Management

COSO Enterprise Risk Management (ERM) – Project Risk Considerations

PMBOK Guide – Schedule Compression Techniques (Crashing & Fast-Tracking)

Thus, the correct and verified answer is D. It is a compression technique in which resources are added so the project is completed faster.

Incremental costs are the most relevant costs when deciding whether to manufacture a new product because they represent the additional costs that will be incurred if the decision is accepted. Management should compare incremental revenues with incremental costs to determine whether producing high-quality backpacks adds value. Fixed costs may be irrelevant if they will not change as a result of the decision. Variable costs are important, but only the additional variable costs caused by the new product matter. Conversion costs include labor and overhead, but they are not necessarily the full relevant cost set. Internal auditors reviewing decision analysis should ensure management excludes sunk costs and includes only future costs that differ between alternatives. Therefore, Option D is correct.

Unauthorized external changes to data are best prevented through layered preventive controls. A firewall restricts unauthorized network access from external sources. Antivirus software helps prevent malicious code from modifying or corrupting data. Data encryption protects data confidentiality and can reduce unauthorized use or alteration when combined with proper key controls. Backup procedures are important recovery controls, but they do not prevent unauthorized changes from occurring. Change logs are detective controls because they record activity after changes occur. Internal auditors evaluating data protection should distinguish preventive, detective, and corrective controls. The best preventive combination listed is antivirus software, firewall, and encryption. Therefore, Option A is correct.

The most effective way to prevent the unauthorized disclosure of confidential information is to limit access based on employee roles and duties. This follows the principle of least privilege (PoLP), ensuring that employees only access the data necessary for their job functions.

(A) Nondisclosure agreements between the firm and its employees. ❌

Incorrect. While NDAs help deter leaks, they do not prevent unauthorized access to information. An employee who signs an NDA can still access and leak data.

(B) Logs of user activity within the information system. ❌

Incorrect. Activity logs help detect and investigate breaches but do not actively prevent unauthorized disclosure.

(C) Two-factor authentication for access into the information system. ❌

Incorrect. While two-factor authentication enhances system security, it does not prevent employees with authorized access from leaking confidential data.

(D) Limited access to information, based on employee duties. ✅

Correct. Role-based access control (RBAC) ensures that employees only access the information necessary for their job responsibilities, reducing the risk of leaks.

IIA GTAG " Identity and Access Management " highlights restricted access as the most effective control for preventing unauthorized disclosure of confidential data.

IIA GTAG – " Identity and Access Management "

IIA Standard 2120 – Risk Management (Data Protection Controls)

COBIT Framework – Information Security and Access Control

Analysis of Answer Choices:IIA References:Thus, the correct answer is D (Limited access to information, based on employee duties), as restricting access is the most effective preventive control against data disclosure.

Classification is a data analytics technique used to assign data elements to defined categories or groups based on shared characteristics or patterns. It can help identify transaction types, customer groups, risk categories, behavioral patterns, or exception classes. Stratification divides numeric values into ranges or bands, often to identify high-value items or distribution patterns. Joining different data sources combines records from separate tables or files, such as vendors and employees. Duplicate testing identifies repeated or potentially duplicate records. Internal auditors may use classification to analyze populations, focus risk assessment, detect unusual groups, or support predictive modeling. Because the question asks about identifying patterns among groups of data elements, Option D is correct.

Contribution margin equals sales revenue minus variable costs. On a per-unit basis, the contribution margin is the selling price of $12 less the variable cost of $7, which equals $5 per unit. For projected sales of 100,000 units, total contribution margin is 100,000 × $5 = $500,000. Fixed costs are not deducted when calculating contribution margin; they are deducted later to determine operating income. If fixed costs of $350,000 were deducted from the $500,000 contribution margin, projected operating income would be $150,000, but that is not what the question asks. Internal auditors reviewing cost-volume-profit calculations should verify that variable costs and fixed costs are classified correctly. Therefore, the correct projected total contribution margin is $500,000, making Option B correct.
