IIA-CIA-Part3 Exam Dumps - Internal Audit Function

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.

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.

The specific identification method is an inventory costing approach where the actual cost of each individual unit sold is recorded. This method is used when items are uniquely identifiable, such as in industries dealing with luxury goods, automobiles, or custom-manufactured products.

Correct Answer (D - Specific identification)

Under the specific identification method, each inventory unit is tracked separately, and its actual purchase cost is assigned to the cost of goods sold (COGS) when sold.

This method is commonly used for high-value, low-volume items where unique tracking is feasible.

The IIA’s GTAG 8: Audit of Inventory Management explains how different costing methods impact financial reporting and internal controls.

Why Other Options Are Incorrect:

Option A (LIFO - Last-in, First-out):

LIFO assumes that the most recent (last-in) inventory is sold first, but it does not track actual unit cost. Instead, it assigns the cost of the newest inventory to COGS.

LIFO is often used for tax benefits but does not follow actual unit cost identification.

Option B (Average cost):

The weighted average cost method calculates an average cost for all inventory units rather than assigning actual unit costs.

This method smooths out price fluctuations but does not track specific items' costs.

Option C (FIFO - First-in, First-out):

FIFO assumes that the oldest (first-in) inventory is sold first, assigning its cost to COGS.

However, like LIFO, it does not track individual unit costs.

IIA GTAG 8: Audit of Inventory Management – Explains different inventory costing methods, including specific identification.

IIA Practice Guide: Assessing Inventory Risks – Covers inventory valuation and fraud risks.

Step-by-Step Explanation:IIA References for Validation:Thus, the specific identification method (D) is the only one that accounts for the actual cost paid for each unit sold.

A tape rotation schedule defines how often backup tapes are overwritten or archived, directly impacting data retention periods. This is essential for compliance, disaster recovery, and internal controls over data storage.

Correct Answer (C - The Tape Rotation Schedule Affects How Long Data is Retained)

Organizations use backup rotation schemes such as Grandfather-Father-Son (GFS), Tower of Hanoi, or FIFO (First-In-First-Out) to determine how long backups are kept before being overwritten.

This impacts data retention policies, regulatory compliance, and recovery capabilities.

The IIA’s GTAG 10: Business Continuity Management discusses backup strategies and retention management.

Why Other Options Are Incorrect:

Option A (System backups should always be performed real-time):

Real-time backups (continuous data protection) are useful but not always required. Many businesses use scheduled backups instead.

Option B (Backups should be stored in a secured location onsite for easy access):

Best practice recommends offsite or cloud storage to protect against disasters like fire or cyberattacks.

Option D (Backup media should be restored only in case of hardware or software failure):

Backups may also be restored for audit purposes, compliance checks, or business continuity testing.

GTAG 10: Business Continuity Management – Covers backup strategies, data retention, and disaster recovery.

IIA Practice Guide: IT Controls – Discusses backup policies and risks in data management.

Step-by-Step Explanation:IIA References for Validation:Thus, the tape rotation schedule (C) is correct because it determines how long data is retained.

To identify very small control and transaction anomalies, internal auditors should analyze the entire dataset rather than a sample. Full population analysis increases the likelihood of detecting:

Unusual transaction patterns, including fraud, errors, and control weaknesses.

Rare or subtle anomalies that might be missed in sampling-based audits.

Machine-learning-based fraud detection and exception analysis.

A. Analysis of the full population of existing data. (Correct)

This approach ensures complete coverage, reduces sampling risk, and detects rare anomalies.

Modern data analytics tools allow auditors to analyze entire datasets efficiently.

B. Verification of the completeness and integrity of existing data. (Incorrect)

While data integrity checks ensure reliable data, they do not actively identify anomalies or suspicious patterns.

C. Continuous monitoring on a repetitive basis. (Incorrect, but relevant)

Continuous monitoring is useful for ongoing fraud detection, but it does not guarantee full anomaly detection unless it covers all transactions.

Full population analysis is more comprehensive for identifying small anomalies.

D. Analysis of the databases of partners, such as suppliers. (Incorrect)

While analyzing external data sources can uncover vendor fraud, it does not address internal control or transaction anomalies within the organization.

IIA GTAG 3 – Continuous Auditing recommends full population analysis as a best practice for anomaly detection.

IIA Standard 1220 – Due Professional Care requires auditors to use advanced analytical techniques to detect control weaknesses.

COSO Framework – Fraud Risk Management Guide suggests full transaction data analysis for effective fraud detection.

Explanation of Answer Choices:IIA References:Thus, the correct answer is A. Analysis of the full population of existing data.

Big data refers to extremely large and complex datasets that require advanced analytics to extract insights. Effective visualization is a crucial step in making big data analytics actionable.

Let’s analyze the options:

A. Big data is often structured.

Incorrect. Big data can be structured, semi-structured, or unstructured. Many sources of big data (e.g., social media, sensor data, emails) are unstructured, making analysis more challenging.

B. Big data analytic results often need to be visualized. ✅ (Correct Answer)

Correct. Due to its complexity, big data analytics results must often be visualized using dashboards, charts, or graphs to communicate insights effectively.

Examples of visualization tools include Tableau, Power BI, and Google Data Studio.

C. Big data is often generated slowly and is highly variable.

Incorrect. Big data is typically generated rapidly and continuously (e.g., social media posts, IoT sensors, financial transactions). This relates to the "velocity" characteristic of big data.

D. Big data comes from internal sources kept in data warehouses.

Incorrect. Big data comes from both internal and external sources, including social media, cloud applications, and sensors. Additionally, data warehouses store structured data, whereas big data is often unstructured and stored in data lakes.

Understanding the Cash Conversion Cycle (CCC):

The Cash Conversion Cycle (CCC) measures the time taken for a company to convert raw materials into cash flow.

CCC is calculated using the formula: CCC=DaysInventoryOutstanding(DIO)+DaysSalesOutstanding(DSO)−DaysPayableOutstanding(DPO)CCC = Days Inventory Outstanding (DIO) + Days Sales Outstanding (DSO) - Days Payable Outstanding (DPO)CCC=DaysInventoryOutstanding(DIO)+DaysSalesOutstanding(DSO)−DaysPayableOutstanding(DPO)

Where:

DIO (Days Inventory Outstanding) = 55 days (time to convert raw materials to finished products).

DSO (Days Sales Outstanding) = 42 days (time to collect receivables).

DPO (Days Payable Outstanding) = 10 days (time to pay for raw materials).

Applying the Formula:

CCC=55+42−10CCC = 55 + 42 - 10CCC=55+42−10 CCC=100 daysCCC = 100 \text{ days}CCC=100 days

Why Option C (100 Days) Is Correct?

The CCC represents the time the company’s cash is tied up in production and sales before receiving payment.

This calculation aligns with IIA Standard 2120 – Risk Management, which requires auditors to assess financial liquidity and operational efficiency.

Why Other Options Are Incorrect?

Option A (26 days): Incorrect calculation.

Option B (90 days): Does not subtract DPO correctly.

Option D (110 days): Incorrect addition of all components instead of following the CCC formula.

The correct cash conversion cycle is 100 days, calculated using standard CCC methodology.

IIA Standard 2120 and financial management principles confirm the correct calculation.

External auditors may rely on internal audit’s work if they evaluate the objectivity, competence, and quality of the internal audit function. If satisfied, they may use internal audit work to support their opinion, reducing duplication.

Option A is incorrect because external auditors do not manage internal audit. Option B is too restrictive, as reliance is allowed under auditing standards. Option D is false because internal audit can share relevant work with external auditors.
