The PRIMARY reason an IS auditor performs a functional walkthrough during the preliminary phase of an audit assignment is to:
A . understand the business process.
B . comply with auditing standards.
C . identify control weakness.
D . plan substantive testing.
Answer: A
Explanation:
Understanding the business process is the first step an IS auditor needs to perform. Standards do not require an IS auditor to perform a process walkthrough. Identifying control weaknesses is not the primary reason for the walkthrough and typically occurs at a later stage in the audit, while planning for substantive testing is performed at a later stage in the audit.
