Certified Information Systems Auditor (CISA) — Question 902

Which of the following is the MOST appropriate control to have in place after data migration?

Answer options

• A. Review of representative samples of migrated data
• B. Clearly defined and documented data migration roles
• C. Formal sign-off by senior management after completion
• D. Mapping of transactions from source to receiving system

Correct answer: A

Explanation

The correct answer is A because reviewing representative samples of migrated data ensures that the data was transferred accurately and meets quality standards. The other options, while important for the overall migration process, do not directly verify the integrity and accuracy of the migrated data itself.
