Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Using automated data extraction tools
Why it's wrong here
Tools help but do not ensure accuracy without verification.
- ✓
Performing a trial migration and reconciling the results
Why this is correct
Trial migration with reconciliation identifies discrepancies before final migration.
- ✗
Assigning a data owner for each data field
Why it's wrong here
Data ownership is important for governance but not a direct accuracy control.
- ✗
Running parallel processing for one month
Why it's wrong here
Parallel processing tests the system but does not guarantee data accuracy alone.
