IIA-CIA-Part3 Exam Dumps - Business Knowledge for Internal Auditing

Comprehensive and Detailed In-Depth Explanation:

A management (audit) trail ensures financial transparency by tracking who initiated, approved, and processed transactions within the general ledger (GL).

Option A (Report on data outside system parameters) is a validity control, not an audit trail.

Option C (Comparison of results with input) ensures accuracy but is not a comprehensive audit trail.

Option D (Error-free processing confirmation) does not track user activity.

Since audit trails require tracking transactions by time and individual, Option B is correct.

Comprehensive and Detailed In-Depth Explanation:

File encryption protects the confidentiality and integrity of information during transmission and storage. It ensures that only authorized recipients can access the data by converting it into an unreadable format.

Option A (Firewalls) – Prevents unauthorized access to networks but does not secure data exchange.

Option B (Activity logs) – Tracks actions but does not protect data confidentiality.

Option C (Antivirus software) – Protects against malware but does not encrypt data in transit.

Thus, file encryption (Option D) is the best security control for protecting exchanged information.

Comprehensive and Detailed In-Depth Explanation:

The Three Lines of Defense Model classifies risk management roles as follows:

First Line of Defense: Operational management responsible for risk controls (e.g., blocking unauthorized traffic, encrypting data).

Second Line of Defense: Risk management and compliance functions that monitor and assess the effectiveness of first-line controls (e.g., reviewing disaster recovery test results).

Third Line of Defense: Independent audit functions providing assurance (e.g., conducting security assessments).

Option C (Reviewing disaster recovery test results) aligns with the second line of defense because it involves oversight and evaluation of IT controls rather than direct execution.

Understanding Vertical Integration:

Vertical integration is a business strategy where a company expands its operations into different stages of its supply chain.

In this case, the chocolate-producing company is moving upstream by producing its own milk rather than purchasing it from suppliers.

Why This Is Vertical Integration:

The company controls more of its supply chain, reducing dependency on external suppliers.

Benefits include:

Cost savings on raw materials (by producing instead of buying).

Improved quality control (since the company controls milk production).

Greater market control (reducing reliance on third-party vendors).

Why Other Options Are Incorrect:

B. Unrelated diversification – Incorrect.

Unrelated diversification occurs when a company expands into a completely different industry (e.g., a chocolate company entering the technology sector).

C. Differentiation – Incorrect.

Differentiation refers to creating unique products to gain a competitive advantage, but the strategy here is about controlling supply, not product uniqueness.

D. Focus – Incorrect.

Focus strategy targets a narrow market segment, but this scenario involves expanding into the supply chain, not focusing on a niche.

IIA’s Perspective on Business Strategy and Risk Management:

IIA Standard 2120 – Risk Management requires auditors to assess the risks and benefits of vertical integration strategies.

COSO ERM Framework advises monitoring operational and financial risks associated with supply chain integration.

Porter’s Value Chain Model supports vertical integration as a way to enhance operational efficiency and cost control.
