PART 1: INTERNAL AUDIT FUNDAMENTALS (35 Questions)
Question 1
According to the 2024 Global Internal Audit Standards™, which of the
following BEST describes the primary purpose of internal auditing?
A) To detect and prevent all fraud within the organization
B) To enhance and protect organizational value by providing risk-based and
objective assurance, advice, and insight
C) To prepare the organization's financial statements in accordance with GAAP
D) To replace the need for external auditors
Answer: B
Rationale: The primary purpose of internal auditing is to enhance and protect
organizational value by providing risk-based, objective assurance, advice, and
insight. Internal auditing does not guarantee the detection of all fraud (Option A)—
that is an unrealistic expectation. Preparing financial statements (Option C) is
management's responsibility. Internal auditing complements, rather than replaces,
external auditors (Option D).
Question 2
Which of the following is a key component of the International Professional
Practices Framework (IPPF) ?
A) The organization's strategic plan
B) The 2024 Global Internal Audit Standards™
C) The organization's code of conduct
D) The external auditor's work papers
Answer: B
, Rationale: The IPPF includes the 2024 Global Internal Audit Standards™,
which provide the mandatory guidance for the internal audit profession. The
organization's strategic plan (Option A) and code of conduct (Option C) are
organizational documents, not IPPF components. External auditor work papers
(Option D) are not part of the IPPF.
Question 3
The audit charter is a formal document that defines the internal audit function's:
A) Budget and staffing levels
B) Purpose, authority, and responsibility
C) Specific audit procedures for each engagement
D) Performance evaluation criteria for auditors
Answer: B
Rationale: The audit charter is a formal document that defines the internal audit
function's purpose, authority, and responsibility. It establishes the function's
position within the organization. Budget and staffing (Option A) are operational
matters. Specific audit procedures (Option C) are developed for individual
engagements. Performance evaluation criteria (Option D) are not part of the
charter.
Question 4
Which of the following BEST describes the difference between assurance
services and advisory services provided by internal audit?
A) Assurance services are always provided to external stakeholders; advisory
services are for internal stakeholders
B) Assurance services involve objective assessments of evidence; advisory
services provide advice and recommendations
C) Assurance services are mandatory; advisory services are optional
D) There is no meaningful difference between the two
