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

The best method to collect job satisfaction data is one that provides anonymous, broad, and consistent feedback while minimizing response bias. Online surveys are the most effective method because they allow employees to express their views freely and ensure statistical reliability in results.

Online Surveys (Correct Answer: A)

Online surveys allow anonymous responses, which encourage honest feedback without fear of retaliation.

Surveys can be distributed randomly, increasing representation and reducing bias.

They allow for large-scale data collection and quantitative analysis, which improves decision-making.

IIA Standard 2120 – Risk Management suggests that internal auditors evaluate employee engagement as part of organizational risk assessments.

Why the Other Options Are Incorrect:

B. Direct Onsite Observations (Incorrect)

Observation helps assess behavior, but it does not capture employees' emotions, satisfaction, or personal concerns effectively.

Employees may alter their behavior when being observed (Hawthorne Effect).

C. Town Hall Meetings (Incorrect)

Town halls encourage group discussion, but employees may be reluctant to share negative opinions publicly.

This format is not anonymous, which reduces the likelihood of honest feedback.

D. Face-to-Face Interviews (Incorrect)

While interviews provide detailed qualitative feedback, they are time-consuming and may not be scalable for large organizations.

Employees may hesitate to be fully honest due to potential supervisor influence.

IIA Standard 2120 – Risk Management (Assessing employee engagement and morale risks)

IIA Standard 2130 – Compliance (Ensuring ethical and employee engagement policies)

IIA Standard 2210 – Engagement Objectives (Using appropriate methodologies for employee feedback collection)

Step-by-Step Justification:IIA References for This Answer:Thus, the best answer is A. Online surveys sent randomly to employees because they ensure confidentiality, broad participation, and reliable data collection.

The scenario describes a security breach where an employee’s smart card access was not updated after relocation. The best way to prevent such incidents is to regularly review access logs to detect and revoke outdated permissions.

Timely Detection of Unauthorized Access:

Regular log reviews allow security teams to identify anomalies, such as an employee accessing a location where they no longer work.

Access Control Auditing:

Periodic reviews help update access rights, ensuring that only authorized personnel have access to specific areas.

Compliance with Security Standards:

IIA Standard 2110 - Governance emphasizes ensuring security measures are effective.

ISO 27001 - Access Control Policies recommends regular access reviews to prevent unauthorized access.

B. Two-level authentication:

While multi-factor authentication enhances security, it would not remove outdated access rights from the system.

C. Photos on smart cards:

A photo helps in identity verification, but it does not prevent unauthorized access if the card remains active.

D. Restriction of access hours:

Limiting access times would not stop an unauthorized user from entering during valid hours.

IIA Standard 2110 - Governance: Internal auditors must assess IT and physical security controls.

IIA Standard 2120 - Risk Management: Ensures risks associated with unauthorized access are managed.

COBIT Framework - Identity and Access Management: Recommends reviewing user access logs for anomalies.

Key Reasons Why Option A is Correct:Why Other Options Are Incorrect:IIA References:Thus, the correct answer is A. Regular review of logs.

Definition of Flexible Budgets:

Flexible budgeting allows organizations to adjust budgeted expenses based on actual performance levels.

Unlike static budgets, flexible budgets provide different financial projections for varying levels of activity.

Why Flexible Budgets are Useful:

They adjust for actual business conditions, making them useful in planning and cost control.

Organizations can compare actual results against the appropriate budget level rather than a single static budget.

Why Other Options Are Incorrect:

A. Exclude fixed costs: Fixed costs are included; only variable costs change with activity levels.

B. Exclude outcome projections: Flexible budgets still use projected outcomes but adjust them based on actual performance.

C. Red flag for weak control: Flexible budgets enhance control by allowing real-time adjustments, making them a best practice rather than a red flag.

IIA GTAG on Financial Management: Covers budgeting methods, including flexible budgeting.

IIA Standard 2120 – Risk Management: Encourages adaptive financial planning for effective risk management.

COSO ERM Framework: Recommends dynamic financial planning, including flexible budgeting.

Relevant IIA References:✅ Final Answer: Flexible budgets project data for different levels of activity (Option D).

When an organization faces unexpected disruptions, such as the inability to receive raw materials due to a military conflict, it should have contingency plans in place to manage such risks.

Contingency Planning for Unforeseen Events (Correct Answer: C)

Contingency plans are designed to prepare for and respond to unexpected disruptions, such as supply chain failures, political instability, or natural disasters.

IIA Standard 2120 – Risk Management requires organizations to have business continuity and disaster recovery plans, which include contingencies for supply chain disruptions.

A well-prepared contingency plan could involve alternative suppliers, stockpiling critical materials, or adjusting production schedules.

Why the Other Options Are Incorrect:

A. Just-in-time (JIT) delivery plans (Incorrect)

JIT is a supply chain management strategy that minimizes inventory and relies on timely delivery.

While JIT increases efficiency, it is not a backup plan for unexpected disruptions.

In fact, JIT makes companies more vulnerable to supply chain interruptions.

B. Backup plans (Incorrect)

A backup plan generally refers to IT/data backup or system recovery strategies, not a comprehensive risk management approach for supply chain issues.

Contingency plans encompass broader business continuity strategies beyond simple backup plans.

D. Standing plans (Incorrect)

Standing plans are routine, long-term procedures for normal operations, such as HR policies or standard operating procedures.

They do not specifically address unexpected crises like supply chain failures due to war.

IIA Standard 2120 – Risk Management (Ensuring business continuity planning)

IIA Standard 2110 – Governance (Assessing organizational resilience strategies)

IIA Standard 2130 – Compliance (Evaluating regulatory and risk mitigation plans)

Step-by-Step Justification:IIA References for This Answer:Thus, the correct answer is C. Contingency plans, as they are specifically designed to address unexpected disruptions like supply chain failures due to military conflict.

Understanding Net Income Overstatement:

Net Income (NI) = Revenue - Expenses

If net income is overstated, then expenses must be understated or revenue must be overstated.

Cost of Goods Sold (COGS) is an expense that directly affects net income.

Why Understated COGS Causes Overstated Net Income:

COGS = Beginning Inventory + Purchases - Ending Inventory

If COGS is understated, expenses are lower than they should be, resulting in a higher net income.

Why Other Options Are Incorrect:

A. Beginning inventory overstated: This would increase COGS (not decrease it), leading to a lower net income.

C. Ending inventory understated: This would increase COGS, reducing net income.

D. COGS overstated: This would result in a lower net income, not an overstatement.

IIA Standards and References:

IIA Standard 2120 – Risk Management: Internal auditors must assess financial misstatements and risks.

IIA Practice Guide: Auditing Financial Statement Close Processes (2018): Emphasizes accuracy in inventory and expense reporting.

COSO Internal Control – Integrated Framework: Supports accuracy in financial reporting and controls over misstated financial data.

Thus, the correct answer is B: Cost of goods sold was understated for the year.

Understanding Predictive Analytics:

Predictive analytics involves using historical data, statistical algorithms, and machine learning techniques to forecast future trends and behaviors.

It applies assumptions and models patterns to predict outcomes, helping businesses make proactive decisions.

Why Option B is Correct:

Predictive analytics is forward-looking and uses assumptions (e.g., weather conditions) to predict where stock levels would decrease more quickly.

This aligns with the goal of predictive analytics: forecasting potential events before they occur.

Why Other Options Are Incorrect:

A. Analyzed instances where parts were out of stock before scheduled deliveries: This is descriptive analytics, as it looks at past data without making future predictions.

C. Analyzed past stockouts and found a correlation with stormy weather: This is diagnostic analytics, as it identifies past correlations but does not predict future trends.

D. Modeled different scenarios for stock reordering and delivery decisions: This is prescriptive analytics, which focuses on decision-making rather than predictions.

IIA Standards and References:

IIA GTAG on Data Analytics (2017): Highlights predictive analytics as a tool for forecasting risks and operational inefficiencies.

IIA Standard 1220 – Due Professional Care: Encourages auditors to use analytical techniques to anticipate potential issues.

COSO ERM Framework: Supports the use of predictive models to improve risk management and strategic planning.

Thus, the correct answer is B: A supplier of electrical parts analyzed sales, applied assumptions related to weather conditions, and identified locations where stock levels would decrease more quickly.

Phishing attacks often target financial institutions by impersonating customers and requesting fraudulent fund transfers. The best way to verify such requests is to independently contact the customer using a trusted communication channel, such as the phone number on record.

Verbal confirmation via a trusted number prevents fraudsters from exploiting email spoofing or compromised accounts.

This aligns with industry best practices, including multi-factor verification for high-risk transactions.

A. Reviewing the customer's wire activity to determine whether the request is typical. (Incorrect)

While reviewing transaction history can help detect anomalies, fraudsters can mimic previous transaction patterns, making this method unreliable on its own.

B. Calling the customer at the phone number on record to validate the request. (Correct)

Direct phone verification ensures that the actual account owner is making the request.

This is a widely recommended anti-fraud measure in financial institutions.

C. Replying to the customer via email to validate the sender and request. (Incorrect)

If the email account is compromised, the fraudster will control the response.

Email validation is not secure for financial transactions.

D. Reviewing the customer record to verify whether the customer has authorized wire requests from that email address. (Incorrect)

While this can help identify unregistered emails, attackers often spoof or hack real customer emails.

Email-based verification alone is not sufficient.

IIA GTAG 16 – Security Risk: IT and Cybersecurity recommends multi-factor authentication for high-risk financial transactions.

IIA Standard 2120 – Risk Management highlights the need for robust fraud prevention mechanisms, including direct customer verification.

FFIEC (Federal Financial Institutions Examination Council) Cybersecurity Guidelines emphasize the importance of out-of-band authentication for wire transfers.

Explanation of Answer Choices:IIA References:Thus, the correct answer is B. Calling the customer at the phone number on record to validate the request.

Key Performance Indicators (KPIs) are used to measure and monitor the effectiveness of a process within an organization. In this case, the internal auditor found that 3% of payments did not match submitted invoices, which indicates a potential control weakness in the accounts payable process.

Process Owner’s Tolerance for Performance Deviations (Correct Answer: A)

The most relevant KPI would be one that sets acceptable error limits for invoice payments.

IIA Standard 2120 – Risk Management states that auditors should assess management's risk tolerance and evaluate whether processes are operating within acceptable limits.

If the organization's threshold for errors is 1% and the audit found 3%, it indicates a significant issue requiring corrective action.

This KPI helps the auditor assess materiality and determine the significance of the 3% deviation.

Why the Other Options Are Incorrect:

B. KPI defining the importance of performance levels and disbursement statistics (Incorrect)

While understanding performance levels and disbursement statistics is useful, this KPI does not directly address error tolerance or the impact of deviations.

C. KPI defining timeliness of reporting disbursement errors (Incorrect)

Reporting errors quickly is important, but this KPI does not help in determining whether a 3% error rate is acceptable or excessive.

D. KPI defining operating ratio objectives (Incorrect)

Operating ratio objectives focus on financial efficiency rather than error tolerance or accuracy in invoice processing.

IIA Standard 2120 – Risk Management (Assessing risk tolerance in financial processes)

IIA Standard 2210 – Engagement Objectives (Evaluating process performance against defined thresholds)

IIA Standard 2130 – Compliance (Ensuring adherence to financial control policies)

Step-by-Step Justification:IIA References for This Answer:Thus, the best answer is A. A KPI that defines the process owner's tolerance for performance deviations, as it directly helps the auditor assess the materiality of the 3% error rate in accounts payable.

The auditor's observation indicates that backup media is stored on-site in the data center, which is a major risk in disaster recovery and business continuity planning (BCP). Best practices recommend storing backup media off-site to prevent data loss due to fires, floods, cyberattacks, or other disasters affecting the primary site.

Off-Site Storage Reduces Disaster Risks:

Keeping backups only at the primary data center means that any physical disaster (fire, flood, theft, or power surge) can destroy both primary and backup data.

Best practices require off-site or cloud-based backup storage to ensure data recovery in case of emergencies.

Regulatory and Compliance Considerations:

IIA Standard 2110 (Governance): Emphasizes disaster recovery policies to protect critical IT assets.

ISO/IEC 27001 (Information Security Management System): Recommends storing backups in a geographically separate location.

NIST SP 800-34 (Contingency Planning Guide for Federal Information Systems): Requires off-site storage to ensure effective disaster recovery.

Why the Other Options Are Incorrect:

B. Backup procedures are adequate and appropriate according to best practices: ❌

Incorrect, as on-site-only storage violates best practices for disaster recovery.

C. Backup media is not properly indexed, as backup media should be indexed by system, not date: ❌

While indexing is important, the main issue here is improper storage, not indexing methods.

D. Backup schedule is not sufficient, as full backup should be conducted daily: ❌

Backup frequency depends on business needs; a weekly backup is common for many organizations.

However, the biggest concern here is lack of off-site storage, not frequency.

IIA GTAG (Global Technology Audit Guide) on Business Continuity and Disaster Recovery: Recommends off-site storage for backups.

ISO/IEC 27001 – Information Security Controls (A.12.3.1): Requires backup data to be securely stored off-site.

COBIT 5 Framework – DSS04 (Manage Continuity): Supports off-site backups for IT continuity.

Step-by-Step Justification:IIA References:Thus, the correct answer is A. Backup media is not properly stored, as the storage facility should be off-site. ✅

Enterprise Resource Planning (ERP) systems integrate various business processes into a unified system, offering numerous benefits. Here's an analysis of the provided options:

A. Real-time Processing of Transactions and Elimination of Data Redundancies:

ERP systems centralize data and standardize processes across an organization. This centralization enables real-time processing of transactions, allowing immediate updates and access to data. By maintaining a single database for all business functions, ERPs eliminate data redundancies, ensuring consistency and accuracy across departments. This integration enhances decision-making and operational efficiency. According to Investopedia, ERP systems facilitate the free flow of communication between business areas, providing a single source of information and accurate, real-time data reporting.

Investopedia

B. Fewer Data Processing Errors and More Efficient Data Exchange with Trading Partners:

While ERP systems can reduce data processing errors through automation and standardized processes, efficient data exchange with trading partners often requires additional tools or modules, such as Electronic Data Interchange (EDI) systems. Therefore, this benefit is not solely attributable to ERP systems.

C. Exploitation of Opportunities and Mitigation of Risks Associated with E-Business:

ERP systems provide a robust infrastructure that can support e-business initiatives. However, effectively exploiting opportunities and mitigating risks in e-business also depend on strategic planning, market analysis, and additional technologies beyond the ERP system itself.

D. Integration of Business Processes into Multiple Operating Environments and Databases:

ERP systems aim to integrate business processes into a single operating environment with a unified database. Integrating into multiple operating environments and databases would contradict the primary purpose of an ERP, which is to provide a centralized platform.

In summary, the most significant benefit of an ERP system among the options provided is the real-time processing of transactions and the elimination of data redundancies, making option A the correct answer.

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.

The high-low method is a technique used in cost accounting to separate variable and fixed costs by analyzing the highest and lowest levels of activity. By computing the difference between the high and low levels of maintenance costs, the clerk determines the variable portion of maintenance costs.

High-Low Method Calculation:

Identify the highest and lowest activity levels and their corresponding costs.

Compute the change in cost (difference between high and low costs).

Compute the change in activity level (difference between high and low activity).

Divide change in cost by change in activity to determine the variable cost per unit.

Variable Costs Identified: The cost that changes with activity level is the variable maintenance cost.

Option A (Fixed maintenance costs): Fixed costs remain unchanged regardless of activity level, but the high-low method focuses on variable costs.

Option C (Mixed maintenance costs): Mixed costs include both fixed and variable components, but the high-low method isolates the variable portion.

Option D (Indirect maintenance costs): Indirect costs refer to overhead expenses, which may or may not be relevant in the high-low method analysis.

IIA’s Business Knowledge for Internal Auditing (CIA Exam Part 3 Syllabus) covers cost accounting concepts, including cost behavior analysis and methods like the high-low approach.

IIA’s Guide on Financial Management & Internal Control supports understanding cost analysis techniques for budgeting and financial planning.

Why Option B is Correct:Why Other Options Are Incorrect:IIA References:Thus, the most appropriate answer is B. Variable maintenance costs.

After upgrading to a new accounting software, it is critical to ensure that the system is functioning correctly and meets the organization's operational, compliance, and security requirements. The immediate priority should be software testing and validation to confirm that:

The upgrade was successfully implemented.

The system is free from major bugs or functionality errors.

Financial data integrity is maintained.

Compliance with accounting and regulatory standards is ensured.

(A) Market analysis to identify trends:

This is unrelated to post-upgrade activities. Market analysis is a strategic function typically handled by business intelligence or marketing teams, not IT software vendors.

(B) Services to manage and maintain the IT infrastructure:

While IT infrastructure maintenance is important, it is typically an ongoing operational task rather than an immediate post-upgrade activity.

(C) Backup and restoration:

While data backup should be completed before the software upgrade, restoration would only be necessary if the upgrade fails. However, this is a contingency plan, not a standard immediate post-upgrade activity.

(D) Software testing and validation (Correct Answer):

Immediately after an upgrade, software testing is critical to ensure that financial transactions, reporting, and other accounting functions operate correctly.

This includes user acceptance testing (UAT), integration testing, and validation against financial reporting requirements.

IIA Global Technology Audit Guide (GTAG) 8: Auditing Application Controls – Emphasizes the importance of testing and validating application functionality after implementation or upgrades.

IIA Standard 2110 - Governance – Requires internal auditors to assess whether IT governance supports the organization's strategic objectives, including testing new software for operational effectiveness.

COBIT (Control Objectives for Information and Related Technologies) Framework – Highlights the importance of post-implementation review to confirm that IT systems perform as expected.

Analysis of Each Option:IIA References:Conclusion:To ensure that the accounting software upgrade is successful and operationally sound, software testing and validation must be performed immediately. Therefore, option (D) is the correct answer.

The discussion between the internal auditor and the database administrator is most likely centered around the security risk present in the period between account creation and password change. When a system generates a default password such as "123456," it introduces a temporary vulnerability until the user changes it.

Understanding Default Password Security Risks:

Default passwords, especially predictable ones (e.g., "123456"), pose a security threat because they are easy to guess.

If an unauthorized user gains access before the legitimate user changes the password, data confidentiality and integrity may be compromised (IIA GTAG - Global Technology Audit Guide).

Evaluating the Window of Exposure:

The primary concern is the time between account creation and password reset.

During this time, an attacker could exploit the default password to gain unauthorized access to sensitive systems.

Why Other Options Are Less Relevant:

Option A (Replacing numbers with characters) – While this improves security, it does not directly address the risk of an attacker exploiting the default password before the user resets it.

Option B (Users continuing to use the initial password) – This is a security issue, but it is mitigated by requiring a password reset upon first login. The primary concern is the time before the reset happens.

Option D (User training on password management) – While training is crucial for long-term security, it does not directly address the immediate vulnerability of default passwords before they are changed.

IIA Global Technology Audit Guide (GTAG) 16: Data Management and Security

IIA Standard 2110 – Governance: Recommends addressing IT security risks, including credential management.

IIA Practice Advisory 2130.A1-1: Internal auditors should assess whether management has identified, assessed, and mitigated IT security risks, such as weak authentication practices.

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.

IIA GTAG 17 – Auditing Network Security highlights the importance of WAN security, VPNs, and encryption when managing international operations.

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

Effective IT Change Management Principles:

Change management ensures that modifications to IT systems are controlled, tested, and implemented in a way that reduces risks.

A structured and consistent process is required to prevent disruptions, maintain system integrity, and comply with governance requirements.

IIA Standard 2110 - Governance:

IT governance must include structured change management processes.

Change management should be repeatable and standardized to ensure effectiveness.

IIA GTAG (Global Technology Audit Guide) on Change Management:

Change management must be conducted in a controlled environment to minimize unintended consequences and security risks.

A. The sole responsibility for change management is assigned to an experienced and competent IT team. (Incorrect)

While IT plays a key role, change management should involve multiple stakeholders, including business units, security, compliance, and risk management teams.

IIA Standard 2120 - Risk Management states that risk oversight should not be assigned to a single function.

C. Internal audit participates in the implementation of change management throughout the organization. (Incorrect)

Internal audit evaluates change management but does not implement it.

IIA Standard 1000 - Purpose, Authority, and Responsibility emphasizes that internal audit provides independent assurance rather than operational involvement.

D. All changes to systems must be approved by the highest level of authority within an organization. (Incorrect)

Approvals should be based on a risk-based hierarchy rather than requiring executive-level approval for all changes.

IIA GTAG - Change Management recommends a tiered approval system based on change complexity and risk impact.

Explanation of Incorrect Answers:Conclusion:The most critical factor in effective IT change management is having a consistent, controlled process (Option B).

The auditor likely omitted the data normalization step, which is crucial when integrating multiple datasets from different sources (e.g., human resources (HR) and payroll). Without normalization, inconsistencies in formatting, naming conventions, or unique identifiers (e.g., employee ID vs. full name) can result in incorrect mismatches.

Standardization of Data Formats:

Employee names or IDs may be stored differently across systems (e.g., "John A. Doe" in HR vs. "Doe, John" in payroll).

Normalization ensures uniform formatting to enable accurate comparisons.

Removal of Duplicates & Inconsistencies:

Employee records could have multiple variations due to typos, abbreviations, or missing fields.

Proper cleaning and transformation of data ensures better accuracy.

Use of Unique Identifiers:

Instead of matching by name, the auditor should have used a unique identifier (e.g., Employee ID), which remains constant across systems.

A. Data analysis (Incorrect)

Reason: The auditor did attempt data analysis (matching employee records) but without proper preparation (normalization), the results were flawed.

B. Data diagnostics (Incorrect)

Reason: Data diagnostics refers to evaluating data quality issues, but it does not involve transforming data to a common format, which was the missing step.

C. Data velocity (Incorrect)

Reason: Data velocity relates to the speed at which data is processed, which is not relevant to the issue of incorrect matching.

IIA Global Technology Audit Guide (GTAG) 16: Data Analysis Technologies – Covers data quality, normalization, and audit data preparation.

IIA GTAG 3: Continuous Auditing – Discusses the importance of accurate data extraction and transformation.

IIA Standard 2320 – Analysis and Evaluation – Ensures appropriate data validation before concluding audit findings.

Why is Data Normalization Important?Analysis of Incorrect Answers:IIA References:Thus, the correct answer is D. Data normalization.

When an organization allows managers to use their own smartphones at work under a Bring Your Own Device (BYOD) policy, IT security and risk management become critical. The most important policy and procedure to include would be documenting the process for discontinuing use of the devices to ensure data security, compliance, and risk mitigation when employees leave the company or change roles.

Data Security & Compliance: Ensuring that sensitive company data is removed securely when an employee leaves or replaces a device is crucial to prevent unauthorized access.

Access Control & Endpoint Management: The IT department needs a clear policy to revoke access to corporate applications and networks when a device is no longer in use.

Risk Mitigation: Unauthorized access to company systems through lost, stolen, or retired devices can lead to security breaches.

Option B (Required removal of personal pictures and contacts): Personal data does not impact company security and is irrelevant to corporate IT policies.

Option C (Required documentation of expiration of contract with service provider): This is the employee's responsibility, not the organization's, and does not address security risks.

Option D (Required sign-off on conflict of interest statement): While conflict of interest policies are important, they are unrelated to IT security concerns related to BYOD.

IIA’s GTAG (Global Technology Audit Guide) on Managing and Auditing IT Vulnerabilities emphasizes the importance of BYOD risk management, including clear procedures for device decommissioning.

IIA's Business Knowledge for Internal Auditing (CIA Exam Syllabus - Part 3) highlights IT governance frameworks that require policies for data access and security when using personal devices.

Why Option A is Correct:Why Other Options Are Incorrect:IIA References:Thus, the most appropriate answer is A. Required documentation of process for discontinuing use of the devices.

The internal auditor compared vendor addresses (Finance Department records) with employee addresses (Payroll Department records). This process is an example of "Joining Data Sources", which involves merging different datasets to identify relationships, discrepancies, or anomalies.

Definition of Joining Data Sources:

This technique is used in data analytics when an auditor merges two or more datasets based on a common field (e.g., addresses in this case).

It helps identify potential conflicts of interest or fraudulent transactions, such as employees creating fake vendors to receive unauthorized payments.

Application in Auditing:

The auditor is cross-referencing records from two different departments to check for potential fraud, duplicate payments, or unauthorized vendor relationships.

If vendor addresses match employee addresses, it could indicate a fraud risk (e.g., an employee making payments to a shell company they control).

A. Duplicate Testing: ❌

Involves identifying duplicate records within a single dataset, such as repeated invoice numbers or duplicate payments to the same vendor.

Here, the auditor is comparing two datasets, not searching for duplicates in one dataset.

C. Gap Analysis: ❌

Identifies missing data or discrepancies between expected and actual records (e.g., missing vendor payments).

In this case, the auditor is not looking for missing data but rather comparing records.

D. Classification: ❌

Involves categorizing data into predefined groups (e.g., classifying vendors as high-risk or low-risk).

The auditor is not categorizing vendors but matching addresses across datasets.

IIA GTAG (Global Technology Audit Guide) – Data Analytics for Internal Auditors: Discusses joining data sources to detect fraud, errors, and conflicts of interest.

IIA Standard 1220 (Due Professional Care): Requires auditors to apply appropriate data analysis techniques to assess risks effectively.

ACFE (Association of Certified Fraud Examiners) – Fraud Detection Techniques: Recommends cross-referencing employee and vendor records to detect fraud schemes.

Step-by-Step Justification:Why Not the Other Options?IIA References:Thus, the correct answer is B. Joining data sources. ✅

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:

Understanding IT Infrastructure Risks and Workstation Security:

Reviewing an organization’s IT infrastructure risks includes assessing the security of workstations (desktops, laptops, and terminals) that connect to the organization's network.

Workstations are vulnerable to physical theft, unauthorized access, and malware attacks, making physical controls a critical security measure.

Why Physical Controls Are the Most Relevant for Workstations:

Physical controls prevent unauthorized physical access, theft, tampering, and damage to workstations.

Examples include:

Locked office spaces or workstation enclosures to restrict access.

Security badges or biometric authentication to prevent unauthorized use.

Cable locks for laptops and desktop computers to deter theft.

Surveillance cameras and security guards to monitor access.

Why Other Options Are Incorrect:

A. Input controls – Incorrect.

Input controls ensure accuracy and completeness of data entry, which applies more to application security, not workstation security.

B. Segregation of duties – Incorrect.

Segregation of duties prevents fraud and conflicts of interest, but it does not directly address workstation security risks.

D. Integrity controls – Incorrect.

Integrity controls ensure data consistency and accuracy in databases and transactions, not workstation security.

IIA’s Perspective on IT Risk and Physical Security Controls:

IIA Standard 2110 – Governance requires organizations to implement physical security measures for IT assets, including workstations.

IIA GTAG (Global Technology Audit Guide) on IT Risks highlights the importance of restricting physical access to IT devices to prevent unauthorized use or data breaches.

ISO 27001 Information Security Standard recommends physical controls to secure IT infrastructure and prevent workstation-related risks.

IIA References:

IIA Standard 2110 – IT Security & Physical Access Control

Comprehensive and Detailed Step-by-Step Explanation with all IIA References:

Understanding the Concern:

Internal auditors must assess risks when using free software for data analysis, particularly regarding data security, confidentiality, and integrity.

When analyzing third-party vendor data, the primary risk is data compromise, unauthorized access, or data loss due to inadequate security controls in free software.

Why Data Security is the Biggest Concern:

Free software often lacks robust security measures, making sensitive vendor data susceptible to breaches, cyberattacks, or loss.

Ensuring compliance with data protection regulations (e.g., GDPR, CCPA) and contractual obligations with third-party vendors is critical.

Why Other Options Are Incorrect:

A. The ability to use the software with ease → While usability is important, security risks outweigh ease of use in an internal audit context.

B. The ability to purchase upgraded features → Upgrades may improve analysis capabilities but do not address security concerns.

D. The ability to download the software → Installing software is a technical issue, not a major audit concern compared to security.

IIA Standards and References:

IIA Standard 2110 – Governance: Internal auditors should ensure data security risks are addressed in technology use.

IIA Standard 2120 – Risk Management: Auditors must evaluate the organization’s ability to safeguard data.

IIA GTAG (Global Technology Audit Guide) on Data Analytics (2017): Recommends ensuring security of third-party data when using analytical tools.

Thus, the correct answer is C: The ability to ensure that big data entered into the software is secure from potential compromises or loss.
