In Marketing Cloud, what tool is used to run queries against data views?

• A. Automation Studio
• B. Email Studio
• C. Contact Builder
• D. Audience Builder

Answer: (B)

SQL-based access to Marketing Cloud’s system data views is performed inside Automation Studio using a Query Activity. Data views like _Open, _Sent, and _Subscribers expose historical and tracking data that you can query with standard SQL and then store the results in a data extension for reporting, automation, or segmentation. Email Studio focuses on creating and sending emails and doesn’t provide a feature to run SQL queries against data views. Contact Builder is for modeling and managing how data relates, not executing queries against system views. Audience Builder is for building audience definitions and segmentation, not for querying data views with SQL. A typical use is writing a query to join a data view with a subscriber data extension and outputting the results to a new data extension for downstream use.
