Python developers connect to Autonomous Database using a dedicated library:

Correct Answer (D): “By using Oracle Client and the cx_Oracle interface” (now renamed oracledb) is the recommended method. The Oracle Client provides the underlying connectivity, and cx_Oracle (or oracledb) is a Python module for database access, supporting wallet-based authentication to Autonomous Database.

Incorrect Options:

A: SQL Developer is a GUI tool, not a Python interface.

B: DBD-oracle is not a standard Python library for Oracle; it’s likely a typo or confusion with Perl’s DBI.

When an Autonomous Database is stopped, limited actions are available:

Correct Answer (B):Startis possible to bring the database back online via the OCI Console or API.

Correct Answer (C):Update License type(e.g., from License Included to Bring Your Own License) can be performed while stopped, as it’s a configuration change not requiring database activity.

Incorrect Options:

A: Changing the admin password requires the database to be running for security validation.

Oracle APEX (Application Express) in Autonomous Database requires a workspace for development:

Correct Answer (A): “Access the APEX Administrator Services and create the workspace for the developer” is the correct step. As an admin, you log into the APEX Administration Services (via Database Actions or a direct URL), navigate to “Manage Workspaces,” and create a new workspace, assigning it to the developer with a schema and credentials.

Incorrect Options:

B: Creating an IDCS (Identity Cloud Service) user with an APEX role manages authentication but doesn’t create a workspace.

C: A database user with an APEX role lacks a workspace; it’s a prerequisite step, not the solution.

Performance Hub in Autonomous Database provides performance monitoring insights. The correct answer is:

24 Hours (C):When you open Performance Hub in the OCI console or Database Actions, the default time range displayed is the last 24 hours, shown in Coordinated Universal Time (UTC). This allows users to review recent performance metrics like CPU usage, SQL activity, and wait times. Users can adjust this range (e.g., to 1 hour or 1 week) as needed.

The incorrect options are:

15 Minutes (A):This is not a default option; it’s too short for a broad performance overview.

1 Hour (B):Available as an option, but not the default setting.

1 Week (D):Also available, but not the default; it’s a longer-term view users can select manually.

The 24-hour default balances recency and context for performance analysis.
