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

Comprehensive and Detailed In-Depth Explanation:

Computer hardware refers to the physical components of a computer system.

Workstation: A high-performance computer designed for technical or scientific applications.

Modem: A device that modulates and demodulates signals for data transmission over communication lines.

Disk drive: A device that reads and/or writes data to a disk storage medium.

Option D lists only physical components, fitting the definition of computer hardware.

In contrast:

Value-added network (option A): A hosted service offering specialized networking services, not a physical component.

Data warehouse (option B): A system used for reporting and data analysis, representing a data storage concept rather than a physical device.

Firewall (option C): While it can be hardware, it is often implemented as software; thus, the term doesn ' t exclusively denote hardware.

Therefore, option D accurately represents a list of computer hardware components.

Electronic Data Interchange (EDI) is a system that allows businesses to exchange documents (purchase orders, invoices, shipping notices) electronically, improving efficiency and accuracy.

Correct Answer (A - A Just-in-Time Purchasing Environment)

Just-in-time (JIT) purchasing requires real-time inventory management to reduce waste and costs.

EDI improves JIT by automating purchase orders, reducing lead times, and preventing stockouts.

The IIA GTAG 8: Audit of Inventory Management highlights that JIT purchasing benefits the most from automation through EDI.

Why Other Options Are Incorrect:

Option B (A large volume of custom purchases):

Custom purchases vary significantly in specifications, making standard EDI transactions less effective.

Option C (A variable volume sensitive to material cost):

While EDI helps with volume fluctuations, cost-sensitive purchasing requires additional financial analysis beyond EDI automation.

Option D (A currently inefficient purchasing process):

EDI improves efficiency, but implementing it in a failing process without first optimizing procedures could lead to automation of inefficiencies.

IIA GTAG 8: Audit of Inventory Management – Discusses automation benefits in JIT purchasing.

IIA Practice Guide: Auditing IT Controls – Covers EDI as a key tool for procurement efficiency.

Step-by-Step Explanation:IIA References for Validation:Thus, the greatest benefit from EDI is in a Just-in-Time (JIT) purchasing environment (A).

If the internal audit activity lacks the necessary skills to perform certain audits, this represents a limitation that could impair internal audit’s ability to meet its responsibilities. The CAE must report such resource or competency limitations to the board.

Options A, B, and D (procedures, forms, or methods) may be adjusted internally, but they do not rise to the level of a significant limitation requiring board reporting. Skills gaps, however, directly impact audit coverage and effectiveness.

Job enrichment increases the depth, responsibility, autonomy, and meaningfulness of a role. Encouraging internal auditors to manage engagements from beginning to end gives them broader ownership over planning, fieldwork, communication, issue resolution, and reporting. This increases professional challenge and accountability, which are classic features of job enrichment. Job sharing divides one role between multiple people. Job shadowing allows one employee to observe another for learning purposes. Job rotation moves employees between different roles or assignments to broaden experience, but it does not necessarily give end-to-end ownership of one engagement. In an internal audit activity, job enrichment can improve motivation, development, judgment, and engagement quality. Therefore, Option C is correct.
