Question 1 Which of the following BEST describes the primary objective of an IS audit?
A. To detect and prevent fraud within the organization

B. To ensure all employees comply with IT policies

C. C. To provide assurance that IT controls are adequate and effective

D. To monitor network traffic for security threats

E. To replace the role of internal management in IT decisions

CORRECT ANSWER: C RATIONALE: The primary objective of an IS audit is to
provide assurance that IT controls are adequate, effective, and aligned with
organizational goals and risk management frameworks. Auditors assess whether
controls are functioning as intended, not to replace management or perform operational
security functions.


Question 2 An IS auditor is planning an audit engagement. Which of the following
should be done FIRST?
A. Prepare the audit report

B. Conduct interviews with IT staff

C. Review prior audit findings

D. D. Understand the business objectives and IT environment

E. Test controls for operating effectiveness

,CORRECT ANSWER: D RATIONALE: Before any audit work begins, the auditor must
understand the business objectives and IT environment. This foundational
understanding guides the entire audit process, including risk assessment, scope
definition, and audit program development.


Question 3 Which audit approach involves testing a sample of transactions from
initiation to final reporting?

A. Compliance testing

B. B. End-to-end tracing (tracing)

C. Substantive testing

D. Vulnerability assessment

E. Control self-assessment

CORRECT ANSWER: B RATIONALE: End-to-end tracing, also known as tracing or a
walkthrough, involves following a transaction from its initiation through all processing
stages to the final output. This helps auditors understand and verify the flow of data and
controls within a system.



Question 4 Which of the following BEST defines audit risk?

A. The risk that fraud will occur and go undetected

B. B. The risk that the auditor expresses an incorrect opinion

C. The risk that the auditee will not cooperate

D. The risk that IT systems will fail during the audit
E. The risk of data loss during audit testing

CORRECT ANSWER: B RATIONALE: Audit risk is the risk that an auditor will express
an incorrect audit opinion — for example, concluding that controls are effective when
they are not. It comprises inherent risk, control risk, and detection risk.


Question 5 An IS auditor discovers a significant control weakness during fieldwork.
What should the auditor do FIRST?
A. Immediately report it to regulatory authorities

,B. Include it in the final audit report without discussion

C. C. Discuss the finding with management for clarification

D. Stop the audit engagement immediately
E. Escalate the issue to the external auditors

CORRECT ANSWER: C RATIONALE: When a significant control weakness is
discovered, the auditor should first discuss it with management to clarify the finding,
understand compensating controls, and verify facts before documenting it in the final
report.



Question 6 Which of the following sampling methods gives every item in the population
an equal chance of being selected?

A. Judgmental sampling

B. Stratified sampling

C. C. Random sampling

D. Cluster sampling

E. Haphazard sampling

CORRECT ANSWER: C RATIONALE: Random sampling ensures that every item in
the population has an equal and independent chance of being selected. This eliminates
auditor bias and supports statistical inference about the full population.


Question 7 Which of the following is the MOST important characteristic of audit
evidence?
A. Volume of evidence collected

B. B. Relevance and reliability of the evidence

C. The method used to collect evidence

D. The cost of collecting the evidence

E. The speed at which evidence is gathered

, CORRECT ANSWER: B RATIONALE: Audit evidence must be both relevant (related
to the audit objective) and reliable (trustworthy and accurate). These two characteristics
determine the quality and usefulness of the evidence in forming audit conclusions.


Question 8 A control self-assessment (CSA) is BEST described as:

A. An audit conducted by external regulators

B. A review of IT systems by vendors

C. C. A process where management assesses their own controls

D. A penetration test performed by IT security
E. An automated scan of network vulnerabilities

CORRECT ANSWER: C RATIONALE: Control Self-Assessment (CSA) is a
methodology where management and staff assess the effectiveness of their own
internal controls. It promotes ownership of controls and can supplement but not replace
formal audits.



Question 9 Which of the following BEST describes inherent risk in an IS audit context?

A. A. The risk existing before any controls are applied

B. The risk that auditors fail to detect errors

C. The risk introduced by poor audit planning

D. The risk caused by weak IT security policies
E. The risk that management overrides controls

CORRECT ANSWER: A RATIONALE: Inherent risk is the susceptibility of an area to
error or irregularity in the absence of controls. It reflects the natural risk level of an
activity before any internal controls are considered.



Question 10 What is the purpose of an audit charter?

A. To define the technical specifications of audit tools

B. B. To formally establish the authority, scope, and responsibility of the audit
function
