DA0-002 Data Acquisition and Preparation Practice Question
Which THREE are best practices for data profiling during acquisition? (Choose three.)
⚠ Common exam trap
Watch out — candidates often confuse 'best practices for acquisition' with 'best practices for transformation,' leading them to select normalization (Option A) as an immediate step rather than a later processing stage.

Correct answer & explanation
✓
Check for completeness
Checking for completeness (Option B) is a best practice during data acquisition because it ensures that all required fields and records are present before further processing. Incomplete data can lead to incorrect analysis or failed transformations, so profiling for missing values or nulls is a fundamental validation step.
