Certified Information Systems Auditor (CISA) — Question 1204

Which of the following is the BEST control to ensure data entered into a calculation program is accurate?

Answer options

• A. Programmed edit checks to prevent entry of invalid data
• B. Reasonableness checks with a data entry range
• C. Manual recalculation of data
• D. Visual verification of data entered

Correct answer: A

Explanation

The correct answer is A because programmed edit checks are designed to automatically validate data input and prevent errors before they occur. Options B, C, and D are less effective as they rely on human intervention or post-entry checks, which can still result in inaccuracies if invalid data is entered initially.
