問題文
During a data import, the administrator notices the source file includes national ID numbers that are not used for any campaign. What is the best practice for handling this personally identifiable information (PII)?
選択肢
- Store the national IDs in the subscriber key field to make them the unique ID, and a government number is issued to exactly one person and so stays distinct across each import.
- Exclude the national ID column so data not needed for marketing is never stored.
- Import the national IDs into a data extension and restrict who can view the field, so the information is on hand in case a future project turns out to need it.
- Import the file as-is and delete the national IDs after the campaign is sent.
