Certified Information Systems Auditor (CISA) — Question 1317

Which of the following is the BEST way for an IS auditor to determine the completeness of data migration?

Answer options

• A. Review migration logs to identify possible failures.
• B. Review the implemented data cleanup process.
• C. Reconcile migrated records with records in the source system.
• D. Examine formal departmental review of the data migration.

Correct answer: C

Explanation

The correct answer is C, as reconciling migrated records with those in the source system provides a direct comparison to ensure all data has been accurately transferred. Options A and B do not directly verify the completeness of the migration, while option D merely reviews the process without confirming data integrity.
