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
✓
Apply data masking to the log fields
Data minimization ensures that only necessary data is collected and stored, reducing the attack surface immediately.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Apply data masking to the log fields
Why this is correct
Masking is an effective method to remove or hide sensitive data before it is persisted.
- ✗
Rotate encryption keys weekly
Why it's wrong here
Key rotation is an operational task, not a design-phase minimization strategy.
- ✗
Implement full-disk encryption
Why it's wrong here
Encryption is a secondary protective measure, not the first step in minimization.
- ✗
Enable verbose logging for debugging
Why it's wrong here
Verbose logging increases the amount of data collected, violating minimization.
