AI0-001 AI Infrastructure and Technologies Practice Question
A team is deploying a model that must comply with GDPR. Users can request deletion of their data. Which TWO practices should be implemented to support this compliance? (Select TWO.)
⚠ Common exam trap
CompTIA often tests the misconception that simply using a vector database or caching mechanism satisfies GDPR deletion requirements, when in fact the critical practice is maintaining the ability to delete user data from all derived artifacts, including training sets and feature stores.
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
✓
Maintain the ability to delete a user's data from training sets and derived features
GDPR's 'right to erasure' requires that upon user request, the organization must delete not only the user's raw data but also any derived features or embeddings that were generated from that data. Without this capability, the model could still indirectly retain user information through trained parameters or feature stores, violating compliance.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable output caching for frequently requested predictions
Why it's wrong here
Caching does not help with data deletion compliance.
- ✗
Validate inputs to prevent prompt injection attacks
Why it's wrong here
Prompt injection is a security concern, not related to data deletion compliance.
- ✗
Use a vector database to store user embeddings
Why it's wrong here
Storing embeddings may actually make it harder to delete user data if embeddings are mixed.
- ✓
Maintain the ability to delete a user's data from training sets and derived features
Why this is correct
Directly supports the right to erasure by allowing removal of user data and any features based on it.
- ✓
Implement data versioning and lineage tracking
Why this is correct
Lineage tracking allows you to identify and delete all data associated with a user.
