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
✓
Truncating or hashing identifiers before ingestion
Data aggregation and truncation/hashing are effective ways to reduce the granularity of data and minimize the presence of identifiable information.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disabling all audit logging
Why it's wrong here
Audit logs are necessary for accountability, not a target for minimization.
- ✓
Truncating or hashing identifiers before ingestion
Why this is correct
This reduces the granularity of data at the entry point of the pipeline.
- ✗
Increasing the retention period for backups
Why it's wrong here
Retention should be minimized, not increased.
- ✗
Storing all raw data in a data lake for future use
Why it's wrong here
This violates the principle of purpose limitation and data minimization.
- ✓
Aggregating data points to a higher level of abstraction
Why this is correct
Aggregation removes the need for individual-level identifiers.
