When a DB system has been successfully deleted, the following operations are allowed:
* Restore the DB system from an existing manual backup(Answer C): Even after the DB system is deleted, you can restore it from any existing manual backups. This allows you to recover the data and configuration from a point-in-time backup.
* View the API call logs on the Audit page(Answer E): You can view the API call logs related to the deleted DB system on the Audit page. These logs provide a record of actions taken on the DB system, including the deletion event.

When creating a new MySQL DB system in the OCI Console, you have the following options:
* High availability(Answer A): This option allows you to create a DB system that can automatically fail over to a standby instance in case of hardware or software failure, ensuring minimal downtime.
* Standalone server(Answer C): This option lets you create a DB system with a single instance, suitable for workloads that do not require high availability or read replicas.

When creating a new DB system with data import, the following conditions apply:
* The data must be stored in an Object Storage bucket in the same OCI region as the new DB system(Answer C): This ensures that the data is readily accessible and can be efficiently imported into the new DB system.
* A valid pre-authenticated request must be provided to access the data(Answer D): This allows secure access to the data stored in the Object Storage bucket without needing to handle credentials directly.
