CIA IIA-CIA-Part2 Exam Questions and Answers PDF

According to IIA guidance, the chief audit executive (CAE) is directly responsible for establishing the objectives, scope, and plan for each engagement. This responsibility ensures that each audit is properly focused and aligned with the overall goals and risk areas of the organization. While maintaining a quality assurance program and providing professional development opportunities are important, they are not solely the CAE's responsibility without management support. Periodic review and approval of the internal audit charter is typically a joint responsibility with senior management and the board. References:

The IIA’s Practice Guide on Developing the Internal Audit Plan.

The primary reason for conducting a preliminary risk assessment during engagement planning is to ensure that significant risks are included in the engagement scope. This assessment helps the internal auditor focus on areas of highest risk, ensuring that the audit provides the most value by addressing the most critical issues that could impact the organization's objectives.

In the risk control map, Risk C is positioned in the upper left quadrant, indicating it is critical (high risk significance) but with a low level of control. This suggests that the current controls are insufficient to mitigate the high level of risk associated with Risk C. For critical risks, a higher level of control is necessary to ensure that the risk is properly managed and mitigated. References:

Discovery sampling is a statistical sampling method that is specifically designed for detecting fraud or other irregularities. It is most appropriate when the auditor expects that deviations or fraud may be rare but significant if found.

Discovery Sampling:

Discovery sampling is used when the auditor is trying to identify at least one occurrence of a particular event, such as fraud. The sample is designed so that if a single error is found, it suggests that more may exist within the population, warranting further investigation.

Application in Fraud Detection:

Discovery sampling is effective in fraud detection because it focuses on identifying whether any instances of fraud exist within a population. This approach is well-suited for situations where even a small number of fraudulent transactions could have a significant impact.

IIA Practice Guide on Statistical Sampling:

The IIA suggests that discovery sampling is appropriate when the goal is to find the presence of an error or fraud, particularly in populations where such occurrences are expected to be infrequent.

Option B (Stop-or-go sampling): This method is used to control the risk of over-auditing when errors are expected to be low, but it is not specifically designed for fraud detection.

Option C (Haphazard sampling): This is a non-statistical sampling method and is not appropriate for systematic fraud detection.

Option D (Stratified attribute sampling): This method divides the population into subgroups but is not specifically aimed at discovering fraud.

Detailed Explanation:Why Not Other Options?Conclusion: Option A is correct because discovery sampling is the most appropriate statistical method for testing a population for fraud, as it is designed to detect even a small number of significant deviations, consistent with IIA guidance.
