Which type of Braze data is automatically collected by the SDK when it activates on a consumer's device?

The correct answer is related to the concept of "out of the box data," which refers to the default data points that the Braze SDK captures automatically upon activation on a consumer's device. This data serves as foundational information that helps in establishing a user profile and enables personalized marketing efforts.

When the SDK activates, it collects essential metrics such as user identifiers, device information, and session details, which provide marketers insights into user behavior and engagement. This automatic collection is crucial because it allows for streamlined data acquisition without the need for additional configuration or intervention from developers or marketers.

On the other hand, custom data and custom events require manual setup and integration, which means they don't get collected automatically upon SDK activation. Standard attributes could refer to key user traits but don’t encompass the full scope of what the SDK captures automatically. Hence, out of the box data is specifically designed to offer quick insights and functionality right from the start.
