DA0-002 Data Governance Practice Question
A data analyst includes a map showing customer locations by zip code. The map reveals exact addresses for a few customers due to data granularity. This violates which principle?
⚠ Common exam trap
Test-takers frequently confuse anonymization with data minimization, thinking the issue is collecting too much data, when the real problem is failing to sufficiently generalize or mask the data to prevent re-identification.

Correct answer & explanation
✓
Anonymization
The map reveals exact addresses for a few customers due to the granularity of zip code data. This directly violates the principle of anonymization, which requires that data be processed in such a way that individuals cannot be identified. By exposing precise locations, the data is no longer anonymized, as it allows re-identification of specific individuals.

- ✓
Anonymization
Why this is correct
The map should have been anonymized to avoid revealing individual addresses.

Informed consent
Why it's wrong here
Informed consent is about permission, not technical anonymization.
- ✗
Data minimization
Why it's wrong here
Data minimization relates to collecting only what is needed, not preventing re-identification.
- ✗
Data quality
Why it's wrong here
Data quality refers to accuracy and completeness, not privacy.
