CISA Information System Auditing Process Practice Question
This CISA practice question tests your understanding of information system auditing process. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An IS auditor is planning an audit of a newly implemented financial system. Which of the following is the PRIMARY consideration when determining the audit scope?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Risk assessment of the financial system
The primary consideration for determining audit scope is a risk assessment of the financial system. ISACA standards require auditors to use a risk-based approach to focus audit efforts on areas with the highest residual risk, ensuring that resources are allocated to the most critical controls and processes. Without a risk assessment, the scope may be too broad or miss key vulnerabilities, such as segregation of duties or access control weaknesses in the new system.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Management's request to include all modules
Why it's wrong here
While management input is valuable, scope is primarily driven by risk.
✗
Previous audit findings and recommendations
Why it's wrong here
Past findings inform but do not solely determine scope; risk is primary.
✓
Risk assessment of the financial system
Why this is correct
Risk assessment identifies areas with highest impact and likelihood, guiding scope.
Clue confirmation
The clue word "primary" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Regulatory requirements applicable to the system
Why it's wrong here
Regulatory requirements are part of risk assessment, not the primary driver.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often select regulatory requirements (Option D) as primary because they are mandatory, but the IS auditor must first perform a risk assessment to determine which regulatory requirements are most relevant and how to scope the audit effectively.
Detailed technical explanation
How to think about this question
Under the hood, risk assessment for audit scoping involves evaluating inherent risk (e.g., complexity of the financial system's transaction processing, interfaces with other systems) and control risk (e.g., design of automated controls like edit checks and reconciliation routines). A real-world scenario is a newly implemented ERP financial module where the risk assessment might prioritize testing of the general ledger posting logic and user access provisioning over less critical modules like fixed assets, based on the likelihood and impact of material misstatement.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CISA exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
