Question: The Chrome and Android Privacy Sandbox supports which two key advertising use cases?
- Interest-based advertising
- Tracking of users across websites and apps
- Seamless data-sharing with advertising brands
- Re-engaging audiences
Explanation
Privacy Sandbox is designed to support advertising use cases without relying on third-party identifiers. Topics API supports relevance by using browser- or device-managed interest signals instead of cross-site tracking. Protected Audience API supports remarketing-style use cases while limiting exposure of individual activity across sites or apps. These approaches help maintain ad relevance and audience activation with stronger privacy protections.
Why the other options are incorrect
Cross-site and app tracking is incorrect because Privacy Sandbox is intended to reduce reliance on tracking across websites and apps.
Seamless brand data sharing is incorrect because Privacy Sandbox does not create unrestricted data-sharing between advertisers and brands.
