Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Perform reconciliation of total record counts and key field sums before and after conversion.
Performing reconciliation of total record counts and key field sums before and after conversion is a direct control to verify that data is accurately transferred without loss or corruption. This ensures data integrity. Option B, implementing encryption for data in transit, is important for security but does not directly address data integrity during conversion. Option C, conducting user acceptance testing, focuses on functionality and user requirements, not on the accuracy of the converted data. Option D, ensuring data mapping documents are approved, is a governance control but does not provide verification of actual data integrity during the conversion process.
