問題文
An engineer at a car-sharing company has to explain to a data platform team how purpose limitation and data minimization lead to different implementations in the same pipeline that ingests trip records. Which pairing of mechanisms is correct?
選択肢
- Purpose limitation is implemented as a check on the read path against a declared purpose; minimization is implemented as a decision about which fields and what granularity enter the pipeline at all.
- The purpose limit is implemented in the contract with the data source and minimization in the retention configuration, so both are settled outside the pipeline before any trip record is ingested at all.
- Both are implemented by access control on the tables, because a reader who cannot read the field cannot misuse it.
- Limiting the purpose is implemented by reducing the fields the pipeline carries so that no field can be used for an unintended purpose, and minimization is implemented by attaching the declared purpose to each record so the platform can see which uses were intended, which means the two mechanisms are the same pair of controls described from opposite ends.
