B. Database Management does not support monitoring Autonomous Databases without enabling advanced features in the Autonomous Database itself.

C. Database Management provides real-time and historical performance data, but is limited to monitoring CPU utilization on Autonomous Databases.

D. Database Management can monitor Autonomous Databases, however, the retention period for performance data is shorter compared to that of non-Autonomous Databases.

A. Customers have full access to the Exadata Infrastructure's hypervisor and can implement custom security policies.

B. Customers are responsible for configuring host-based firewalls on the Exadata Infrastructure to protect against unauthorized access.

C. Oracle manages all security aspects of the Exadata Infrastructure, relieving customers of any security responsibilities.

D. Customers are responsible for configuring and maintaining the security of the operating system and database software within the VM Clusters.

E. Network Security Groups (NSGs) can be used to control network traffic to and from VM Clusters, enhancing security.

A. It automatically validates the integrity of full backups during the backup process.

A. Utilize the vmcli utility, which allows access to OS-level metrics specific to the DB System.

B. All OS metrics are automatically pushed to the Cloud Exadata Service Dashboard, and are not available outside of this service.

C. Access OS metrics using the OCI Metrics Explorer within the OCI Console leveraging the Oracle Cloud Agent.

D. The only way to access OS-level metrics is through a custom monitoring agent installed directly on the VM.

E. Access OS metrics programmatically via the OCI Monitoring APIs, which allow retrieval of metrics collected by the Oracle Cloud Agent.
