Show answer & explanation
Correct answer: B — It handles web application requests, user authentication, and content permissions.
- A. Incorrect. Translating user interactions into SQL or MDX queries and rendering visualizations is the primary role of the VizQL Server, not the Application Server.
- B. Correct. The Application Server (VizPortal) handles the web application interface, coordinates user authentication, manages user sessions, and enforces content permissions and administrative functions via the web UI and REST API.
- C. Incorrect. Storing the server's metadata, including user definitions and workbook metadata, is the responsibility of the Tableau Server Repository (a PostgreSQL database).
- D. Incorrect. Managing the extraction of data and storing extracts locally is handled by the Data Engine (Hyper) for query processing and the Backgrounder for the execution of extract refreshes.
