Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Perform data profiling
Data profiling is the initial step to understand the structure, quality, and issues in the data. Rejecting or transforming without profiling may lead to errors, and contacting the vendor is premature without understanding the scope.
