The correct IAM policy to use to allow a group called DatabaseAdmins to create Exadata Database Services is to allow the group to manage the database-family resource type in the tenancy. The database-family resource type includes all the resources related to Oracle Database services, such as DB systems, databases, backups, patches, and Exadata infrastructure1. The syntax for the policy statement is as follows2:

Allow group DatabaseAdmins to manage database-family in tenancy

This policy statement grants the DatabaseAdmins group the permission to perform any action on any resource in the database-family resource type within the tenancy. This includes creating, updating, deleting, and viewing Exadata Database Services and other database resources12.

The other options are not correct IAM policies to use for this purpose. Option A is not a valid syntax, as the tenancy cannot be used as a target for a policy statement. Option B is not a valid syntax, as the databases cannot be used as a principal for a policy statement. Option D is not sufficient, as it only grants the permission to create database-family resources, but not to manage them. Option E is not comprehensive, as it only grants the permission to manage databases, but not other database-family resources, such as Exadata infrastructure12. References:

Oracle database with Object Storage in Oracle Cloud Infrastructure (OCI) can be used for the following use cases:

• Database backups: Oracle Recovery Manager (RMAN) is an Oracle Database client that performs Oracle database backup and recovery. It automates the administration of Oracle backup strategies and greatly simplifies backing up, restoring, and recovering database files. RMAN can use OCI Object Storage as a backup destination, which offers reliable and cost-efficient data durability1.
• Database log files: Oracle Database can use OCI Object Storage as a destination for archiving redo log files, which are generated during normal database operation and contain a record of the changes made to the database. Archiving redo log files to OCI Object Storage can help reduce the storage costs and improve the availability and disaster recovery of the database2.

The other two options are not valid use cases for Oracle database with Object Storage in OCI:

• Database data files: Oracle Database cannot use OCI Object Storage as a storage option for data files, which store the actual data of the database. Data files require block storage, which provides low latency and high performance. OCI Object Storage is an object storage service, which provides high scalability and durability, but not low latency and high performance3.
• Database binaries: Oracle Database cannot use OCI Object Storage as a storage option for database binaries, which are the executable files and libraries that make up the Oracle Database software. Database binaries require a file system, which provides a hierarchical structure and metadata for files and directories. OCI Object Storage is an object storage service, which provides a flat namespace and metadata for objects3.

To use the MySQL Database Service, you need to have the following three prerequisites1:

• You must create a tenancy and be able to sign in to it. A tenancy is a secure and isolated partition within Oracle Cloud Infrastructure where you can create, organize, and administer your cloud resources2. You need to have a valid Oracle Cloud account and credentials to access your tenancy and use the MySQL Database Service.
• You must create a compartment to store your resources. A compartment is a logical container that you can use to organize and isolate your cloud resources within a tenancy3. You can create one or more compartments to store your MySQL Database Service resources, such as MySQL DB systems, backups, and connections. You can also control the access and permissions for each compartment using policies4.
• You or your group must be granted the policies described in Mandatory Policies. Policies are documents that specify who can access which resources, and how5. To use the MySQL Database Service, you need to have the necessary permissions to create and manage the MySQL Database Service resources, as well as the related Oracle Cloud Infrastructure resources, such as Virtual Cloud Networks, subnets, and security lists. The documentation provides a list of mandatory policies that you or your group must be granted to use the MySQL Database Service.

D is incorrect, because you do not have to download the latest MySQL version from The MySQL Database Service is a fully managed service that provides you with the MySQL version that you select when creating a MySQL DB system. You do not have to download or install any MySQL software on Oracle Cloud Infrastructure.

E is incorrect, because you do not have to install the downloaded MySQL version onto Oracle Cloud Infrastructure. As mentioned above, the MySQL Database Service is a fully managed service that handles the installation and configuration of the MySQL software for you.
