You are the admin user of an Autonomous Database instance.

Full Detailed In-Depth Explanation:

To enable a business analyst to use Autonomous Database Data Tools (e.g., Data Load, SQL Developer Web), specific permissions are required:

REST-enabled user:Data Tools rely on REST APIs, necessitating a user with REST support enabled.

Connect and object privileges:These allow database access and interaction with tables.

DWROLE role:This predefined role grants a comprehensive set of privileges for data analysis tasks in Autonomous Data Warehouse (ADW), including SELECT, EXECUTE, and data loading capabilities.

Evaluating the options:

A:Correct. Creating a REST-enabled user with connect/object privileges and granting DWROLE ensures full access to Data Tools, tailored for ADW exploration.

B:Incorrect. Default privileges are minimal and insufficient for Data Tools usage.

C:Incorrect. While connect, resource, and object privileges provide basic access, they lack the REST enablement and DWROLE’s specific analysis permissions.

D:Incorrect. An IDCS (Identity Cloud Service) user is for OCI authentication, not database-level access, and this step overcomplicates the process.
