Autonomous Database provides predefined roles tailored to specific use cases. The correct answer is: DWROLE (B): The DWROLE predefined role is designed for Data Warehouse developers. It includes privileges commonly needed for data warehousing tasks, such as creating tables, views, and materialized views, as well as executing analytical queries. This role is optimized for Autonomous Data Warehouse (ADW) workloads. The incorrect options are: ADBDEV (A): There is no predefined ADBDEV role in Autonomous Database; this appears to be a fictional or misinterpreted role. ADMIN (C): The ADMIN role is a superuser role with full database privileges, far exceeding the needs of a typical Data Warehouse developer and not tailored to that specific use case. ADWC (D): This is not a predefined role; it might be a typo or confusion with ADW (Autonomous Data Warehouse), but no such role exists. DWROLE is the best fit for a Data Warehouse developer’s needs.
