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

A mechanistic organizational structure is a highly structured, hierarchical, and rigid system with well-defined roles, centralized authority, and formalized processes. It is best suited for stable environments where efficiency and control are priorities.

Highly centralized decision-making

Strict hierarchy and formalized job roles

Low flexibility and innovation

Heavy reliance on formal policies, procedures, and direct supervision

(A) Primary direction of communication tends to be lateral.

Incorrect: Mechanistic structures favor vertical communication (top-down or bottom-up), not lateral (horizontal) communication.

IIA Standard 2110 – Governance emphasizes clear roles and responsibilities, which are strictly followed in mechanistic structures.

(B) Definition of assigned tasks tends to be broad and general.

Incorrect: In a mechanistic structure, tasks are specific, well-defined, and specialized, unlike in an organic structure where roles are more flexible.

COSO ERM – Control Environment highlights well-defined roles in structured environments.

(C) Type of knowledge required tends to be broad and professional.

Incorrect: Mechanistic structures rely on specialized and technical knowledge, not broad, generalized knowledge.

(D) Reliance on self-control tends to be low. (Correct Answer)

Mechanistic structures depend on external control mechanisms like supervision, rules, and formal procedures.

Employees have little autonomy, and self-control is not a primary governance mechanism.

IIA Standard 2200 – Engagement Planning stresses the importance of structure in ensuring compliance, aligning with mechanistic principles.

IIA Standard 2110 – Governance: Defines structured governance mechanisms in hierarchical organizations.

COSO ERM – Control Environment: Emphasizes reliance on formal controls in rigid structures.

GTAG 1 – Information Technology Risks and Controls: Highlights the need for structured controls in mechanistic environments.

Characteristics of a Mechanistic Structure:Analysis of Each Option:IIA References Supporting the Answer:Thus, the correct answer is (D) because mechanistic organizations rely heavily on external controls rather than self-regulation.

The equity method is used when an investor owns between 20% and 50% of another company’s stock, indicating significant influence over the investee. Since the investor organization is purchasing 40% of the stock, it qualifies for this method.

(A) Cost method.

Incorrect: The cost method is used when the investor has less than 20% ownership and no significant influence.

(B) Equity method. (Correct Answer)

The equity method is required when the investor has significant influence over the investee (typically between 20% and 50% ownership).

Under this method, the investor records a proportional share of the investee’s profits and losses in its financial statements.

IIA Standard 2330 – Documenting Information recommends accurate financial reporting and appropriate accounting method selection.

(C) Consolidation method.

Incorrect: The consolidation method is used when the investor owns more than 50% of the stock, granting control over the investee.

(D) Fair value method.

Incorrect: The fair value method applies when investments are traded in active markets and do not grant significant influence.

IIA Standard 2330 – Documenting Information: Requires appropriate classification of financial investments.

GAAP & IFRS Accounting Standards: Mandate the equity method for ownership between 20% and 50% with significant influence.

Analysis of Each Option:IIA References Supporting the Answer:Thus, the correct answer is (B) Equity method, as 40% ownership implies significant influence, requiring the use of this method.

The issue described suggests a systemic authorization flaw, where users gain unrestricted access once logged in. This points to an improperly configured authorization system, which should enforce role-based or least-privilege access to restrict users based on their job responsibilities.

(A) Incorrect – The authentication process relies on a simple password only, which is a weak method of authorization.

While weak authentication is a security risk, the issue described relates to excessive access permissions, not weak login credentials.

(B) Correct – The system authorization of the user does not correctly reflect the access rights intended.

The problem is that users have access to all functionality, which indicates an authorization issue, not an authentication flaw.

Proper role-based access controls (RBAC) should limit user permissions based on job functions.

(C) Incorrect – There was no periodic review to validate access rights.

While periodic reviews are important for detecting unauthorized access, the issue here is a system-level authorization design flaw rather than a failure in periodic reviews.

(D) Incorrect – The application owner apparently did not approve the access request during the provisioning process.

Even if an access request was approved incorrectly, the broader issue remains that all users have unrestricted access, which suggests a system misconfiguration rather than a single provisioning error.

IIA’s GTAG (Global Technology Audit Guide) – Access Control and Authorization

Emphasizes the need for role-based access control (RBAC) to prevent unauthorized access.

COBIT Framework – IT Security Governance

Discusses proper authorization mechanisms to align system access with business needs.

NIST Cybersecurity Framework – Access Management Controls

Recommends restricting access rights based on the principle of least privilege (PoLP).

Analysis of Answer Choices:IIA References and Internal Auditing Standards:

Remote wipe is a security feature used in mobile device management (MDM) that allows an organization to erase data from a device remotely. This is critical in cases where a device is lost, stolen, or compromised, ensuring that sensitive corporate data is protected.

(A) It can restore default settings and lock encrypted data when necessary.

Partially correct but not the best answer. Remote wipe does erase data but does not necessarily lock encrypted data unless additional security features are enabled.

(B) It enables the erasure and reformatting of secure digital (SD) cards.

Incorrect. Many remote wipe solutions do not erase external SD cards due to hardware limitations. Users often need separate encryption for SD card data.

(C) It can delete data backed up to a desktop for complete protection if required.

Incorrect. Remote wipe only affects the device itself; it cannot erase backups stored on a desktop or local drives.

(D) It can wipe data that is backed up via cloud computing. ✅

Correct. Many MDM solutions offer the ability to remove access to corporate cloud data, revoke credentials, and remotely erase cloud-stored business files (such as OneDrive, Google Drive, or iCloud backups).

IIA GTAG "Auditing Cybersecurity Risk" emphasizes the importance of managing remote access and cloud-based data protection.

IIA GTAG – "Auditing Cybersecurity Risk"

IIA Practice Guide – "Assessing Mobile Device Security"

IIA Standard 2110 – Governance (IT security controls)

Analysis of Answer Choices:IIA References:Thus, the correct answer is D, as modern remote wipe features allow organizations to remove data from cloud backups, reducing data leakage risks.
