Certified Information Systems Auditor (CISA) — Question 769

Which of the following is MOST important for an IS auditor to verify when reviewing a management information system (MIS)?

Answer options

• A. Backup frequency
• B. Data quality
• C. Data access
• D. System performance

Correct answer: B

Explanation

The correct answer, B. Data quality, is crucial because it ensures that the information generated by the MIS is accurate and reliable for decision-making. While backup frequency, data access, and system performance are important components of an MIS, they do not directly impact the integrity and usefulness of the data being processed.
