Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Prevention of inference attacks where attributes can be predicted
Why this is correct
Even without direct identity, sensitive attribute prediction is a risk.
- ✗
Requirement for user consent
Why it's wrong here
Anonymization is often used specifically to move data outside the scope of consent.
- ✗
Encrypting the data with AES-256
Why it's wrong here
Encryption is reversible if the key is leaked, so it is not true anonymization.
- ✓
Protection against linkage attacks using quasi-identifiers
Why this is correct
Quasi-identifiers can be used to re-identify records.
- ✓
Removal of all direct identifiers
Why this is correct
Essential to prevent direct linkage.
