Certified Information Systems Auditor (CISA) — Question 569

Which of the following application input controls would MOST likely detect data input errors in the customer account number field during the processing of an accounts receivable transaction?

Answer options

• A. Limit check
• B. Reasonableness check
• C. Validity check
• D. Parity check

Correct answer: C

Explanation

A validity check is designed to confirm that the data entered falls within a predefined set of acceptable values or formats, making it the most suitable option for identifying errors in the customer account number field. In contrast, a limit check evaluates whether a value is within a specified range, a reasonableness check assesses if the data seems plausible, and a parity check is used for error detection in data transmission rather than data entry.
