DA0-002 Data Acquisition and Preparation Practice Question
A financial institution needs to acquire credit transaction data from multiple sources while ensuring compliance with data privacy regulations. What is the most critical step?
⚠ Common exam trap
Candidates often confuse operational efficiency measures (replication, compression) or data enhancement (enrichment) with privacy compliance, overlooking that anonymization must be applied at the earliest point of data acquisition to satisfy regulatory requirements.

Correct answer & explanation
✓
Data anonymization during extraction
Data anonymization during extraction is the most critical step because it ensures that personally identifiable information (PII) is irreversibly masked or removed before the data enters the processing pipeline, directly addressing compliance with regulations such as GDPR and PCI DSS. Without this step, even if other measures are applied later, the initial exposure of sensitive data violates privacy mandates and increases breach risk.
