Question: What is one way that a clean room maintains privacy?
- Restricting access to only the advertiser's internal team.
- Pseudonymized signals – identifiers are made into unidentifiable strings of data.
- Limiting access to only senior marketing executives.
Explanation
Pseudonymized signals help protect privacy by replacing direct identifiers with non-identifying strings. Amazon Marketing Cloud uses privacy-safe inputs and controls so analysis can occur without exposing individual customer identities. This allows advertisers to evaluate aggregated patterns while reducing the risk of re-identification. It is a core clean room mechanism for enabling collaboration and measurement with protected data.
Why the other options are incorrect
Advertiser's internal team is incorrect because privacy is not maintained only by restricting access to one organization.
Senior marketing executives is incorrect because role seniority does not define clean room privacy protection.
