Which built-in view provides insights into traffic to views?

The correct answer is "Traffic to Views," which is specifically designed to provide comprehensive insights into the traffic related to views in Tableau. This built-in view presents essential metrics such as the number of times views have been accessed, the users who accessed them, and the frequency of accesses over time. By analyzing this data, users can determine engagement levels with specific views and identify trends in user interaction, which can be pivotal for optimizing content and ensuring that critical dashboards are meeting the needs of their audience.

In contrast, the other options serve different purposes. "Actions by Recent Users" tracks interactions performed by users but does not specifically focus on traffic metrics for views. "Data Quality Warning History" logs issues related to data quality rather than view interactions, while the "Backgrounder Dashboard" provides insights into the background tasks processed by Tableau Server, including performance metrics and scheduling but again does not concentrate on view traffic.
