IIA Updated IIA-CIA-Part3 Exam Questions and Answers by rylee

The internal rate of return (IRR) is a measure used to evaluate the profitability of an investment. The project is considered acceptable if its IRR is greater than or equal to the required rate of return (RRR), which is the minimum return an organization expects from an investment.

Correct Answer (C - Compare to the Required Rate of Return)

The required rate of return (RRR) represents the minimum acceptable return for the project.

If IRR ≥ RRR, the project is acceptable. If IRR < RRR, the project is rejected.

The IIA Practice Guide: Auditing Capital Investments suggests comparing IRR to the RRR to ensure financial feasibility.

Why Other Options Are Incorrect:

Option A (Compare to the annual cost of capital):

The cost of capital (WACC - Weighted Average Cost of Capital) is an important factor, but RRR is the direct benchmark for IRR comparison.

Option B (Compare to the annual interest rate):

Interest rates do not determine project feasibility—they only affect financing costs.

Option D (Compare to the net present value - NPV):

NPV and IRR are related, but they serve different purposes.

IRR is compared against RRR, while NPV measures absolute profitability in dollar terms.

IIA Practice Guide: Auditing Capital Investments – Discusses IRR, RRR, and investment decision-making.

IIA GTAG 3: Business Case Development – Explains how financial metrics like IRR and RRR are used in decision-making.

Step-by-Step Explanation:IIA References for Validation:Thus, C is the correct answer because IRR should be compared to the required rate of return to determine project acceptability.

A data privacy policy outlines how an organization collects, stores, processes, and protects personal data. It should comply with global data protection regulations such as GDPR, CCPA, and IIA guidelines on data security.

(1) Stipulations for deleting certain data after a specified period of time. ✅

Correct. Many data protection laws (e.g., GDPR Article 5) require organizations to delete personal data after a defined retention period to reduce data breach risks.

(2) Guidance on acceptable methods for collecting personal data. ✅

Correct. A privacy policy must define legal and ethical ways to collect personal data (e.g., user consent, lawful processing).

(3) A requirement to retain personal data indefinitely to ensure a complete audit trail. ❌

Incorrect. Retaining personal data indefinitely violates most data privacy regulations (e.g., GDPR Right to Be Forgotten). Data must be stored only for as long as necessary.

(4) A description of what constitutes appropriate use of personal data. ✅

Correct. A privacy policy should clearly define how collected data can and cannot be used to prevent misuse and ensure compliance.

IIA GTAG – "Auditing Privacy Risks"

IIA Standard 2110 – Governance (Data Protection & Privacy)

GDPR (General Data Protection Regulation) – Articles 5 & 17 (Data Retention & Deletion)

Analysis of Answer Choices:IIA References:Thus, the correct answer is C (1, 2, and 4 only) because data should not be retained indefinitely, and the policy must include data collection, retention, and appropriate usage guidelines.

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.

Authentication is a key security control that prevents unauthorized users from accessing a smart device’s data or applications. It ensures that only authorized individuals can use the device, reducing risks such as data breaches, identity theft, and cyberattacks.

(A) Anti-malware software.

Incorrect. Anti-malware software protects against malicious programs, but it does not control user access to a device.

(B) Authentication. ✅

Correct. Authentication mechanisms (such as passwords, biometrics, PINs, and two-factor authentication) prevent unauthorized access to a device’s data and applications.

IIA GTAG "Managing and Auditing IT Vulnerabilities" highlights authentication as a primary control for protecting smart devices.

(C) Spyware.

Incorrect. Spyware is a security threat, not a preventive control. It is a type of malicious software that steals data from a device.

(D) Rooting.

Incorrect. Rooting (on Android) or jailbreaking (on iOS) refers to modifying a device to remove security restrictions, which increases security risks rather than preventing unauthorized access.

IIA GTAG – "Managing and Auditing IT Vulnerabilities"

IIA Standard 2120 – Risk Management

NIST Cybersecurity Framework – Identity and Access Management

Analysis of Answer Choices:IIA References:Thus, the correct answer is B, as authentication is the most effective security control for preventing unauthorized access to smart devices.
