GRADED | COMPREHENSIVE Q&A FOR EXAM
PREP 2026/2027
Question 1. Which statement best describes the primary purpose of internal auditing
within an organization?
A. To prepare the organization's financial statements and approve all journal entries.
B. To provide independent, risk-based assurance and advice that improve governance, risk
management, and control processes.
C. To assume responsibility for implementing management's operational decisions.
D. To guarantee that fraud and financial misstatements never occur.
Answer: B
Rationale: Internal auditing provides independent and objective assurance and advisory
services designed to add value and improve organizational operations. Internal auditors
evaluate governance, risk management, and controls without assuming management's
responsibilities or guaranteeing the elimination of all risks.
Question 2. During an assurance engagement, an internal auditor discovers that the
department manager responsible for the area under review previously supervised the
auditor. The manager offers to approve the auditor's workpapers to speed up the
engagement. What is the most appropriate action?
A. Accept the arrangement because the manager has operational knowledge of the department.
B. Continue the engagement without disclosure because the auditor believes the work will
remain objective.
C. Ask the manager to review only the high-risk findings.
D. Disclose the potential impairment to the appropriate engagement supervisor and follow the
organization's safeguards for maintaining objectivity.
Answer: D
,Rationale: A prior supervisory relationship may create an actual, potential, or perceived
impairment of objectivity. The auditor should disclose the circumstance promptly and allow
appropriate management of the engagement to determine safeguards or reassignment when
necessary.
Question 3. An internal auditor identifies a recurring weakness in the process used to
approve supplier payments. Which action best demonstrates a risk-based approach to
planning the engagement?
A. Assess the likelihood and potential impact of unauthorized payments, evaluate existing
controls, and prioritize procedures accordingly.
B. Test every payment transaction in chronological order, regardless of risk.
C. Focus exclusively on transactions that resulted in confirmed financial losses.
D. Use the previous year's audit program without considering changes in the process.
Answer: A
Rationale: Risk-based planning directs audit resources toward areas with the greatest
potential exposure. Assessing inherent risks, existing controls, likelihood, and impact helps
determine the nature, timing, and extent of audit procedures.
Question 4. Which situation most clearly represents a deficiency in segregation of duties?
A. One employee prepares purchase orders while another approves them.
B. A supervisor reviews monthly bank reconciliations prepared by an accountant.
C. One employee creates suppliers, approves invoices, and releases payments without
independent review.
D. Different employees maintain inventory records and conduct periodic physical counts.
Answer: C
Rationale: Combining supplier creation, invoice approval, and payment release in one
person's hands creates opportunities for unauthorized transactions and concealment.
Segregating authorization, custody, recording, and reconciliation duties reduces this risk.
Question 5. An internal auditor receives an anonymous allegation that a senior executive
has been directing employees to falsify performance reports. No supporting documentation
has yet been provided. What should the auditor do first?
A. Conclude that fraud has occurred because the allegation concerns a senior executive.
,B. Assess the allegation's credibility and significance, preserve confidentiality, and follow
established escalation and investigation procedures.
C. Inform all employees immediately so that witnesses can prepare their statements.
D. Ignore the allegation unless the complainant provides a signed statement.
Answer: B
Rationale: An allegation is a risk indicator, not proof of misconduct. The auditor should assess
the available information, consider the potential significance, protect sensitive information,
and follow appropriate reporting and investigation protocols without prejudging the
outcome.
Question 6. Management requests that an internal auditor remove a significant control
deficiency from a draft report because the department has promised to correct it next
quarter. The evidence supporting the finding is sufficient. What is the most appropriate
response?
A. Remove the finding because management has accepted responsibility for the control.
B. Replace the finding with a general statement about continuous improvement.
C. Delay the report until management completes the corrective action.
D. Retain the supported finding and accurately communicate management's response and
planned corrective action.
Answer: D
Rationale: Internal audit reports must communicate significant findings accurately and
objectively. A proposed corrective action does not eliminate an existing deficiency.
Management's response and implementation timetable can be included without suppressing
relevant evidence.
Question 7. Which document most directly establishes the internal audit activity's purpose,
authority, and responsibility?
A. The internal audit charter.
B. The annual financial statements.
C. The organization's marketing plan.
D. The external auditor's management letter.
, Answer: A
Rationale: The internal audit charter formally establishes the internal audit activity's
mandate, organizational position, authority, and responsibilities. It should be consistent with
applicable professional standards and approved by the appropriate governing body.
Question 8. An auditor selects 40 purchase transactions from a population of 8,000
transactions. What is the primary limitation of this sample?
A. Sampling is inappropriate whenever the population exceeds 1,000 items.
B. A sample automatically establishes whether every transaction is correct.
C. The sample provides evidence about the population but introduces sampling risk and may not
detect every exception.
D. A sample cannot be used to evaluate control effectiveness.
Answer: C
Rationale: Sampling allows auditors to obtain evidence efficiently, but sample results do not
provide absolute certainty about the entire population. Sampling risk arises because a
selected sample may not represent the population accurately or may fail to include relevant
exceptions.
Question 9. During a payroll audit, the auditor notices that several employees share the
same bank account number. What should the auditor do next?
A. Immediately classify all employees involved as fictitious.
B. Investigate the exceptions by verifying employee identities, authorized arrangements, and
supporting payroll records.
C. Delete the affected employees from the payroll system.
D. Report a confirmed fraud finding before obtaining further evidence.
Answer: B
Rationale: Shared bank accounts may indicate fraud, but legitimate explanations can exist.
The auditor should investigate the exception, obtain corroborating evidence, and evaluate
whether the circumstances indicate an actual control failure or misconduct.
Question 10. Which evidence would generally provide the strongest support for the
existence of inventory recorded in a warehouse?
