Which statement is true regarding the naming and management of ATP databases?

The statement regarding ATP databases that is true is that a database name cannot be used concurrently for both ADW and ATP databases. This means that Oracle Autonomous Database imposes a unique naming convention where each database must have a distinct name. Autonomous Transaction Processing (ATP) and Autonomous Data Warehouse (ADW) are considered separate products with their specific use cases, and leveraging the same database name for both types would lead to confusion and potential conflicts in database management tasks.

The uniqueness of database names helps maintain clarity and avoids issues with resource allocation, identity management, and operational oversight. Each database type serves different purposes, with ATP optimized for transaction processing and ADW designed for analytical workloads. Therefore, ensuring that names do not overlap is crucial for managing these resources effectively.

The other statements about database management have limitations or inaccuracies. The immediate reuse of a database name after termination, the maximum core limits, and the storage maximum for an ATP database are subject to Oracle's current configurations and specifications. While it's important to understand those capabilities, they do not pertain to the unique naming convention required for ATP and ADW databases as highlighted in the correct statement.
