Regional Resources

BD.

The correct answers are B. Compartments and E. Block volume backups.

Explanation:

Oracle Cloud Infrastructure (OCI) is a cloud platform that provides a wide range of services and resources to help organizations run their applications and workloads in the cloud. Some of these resources are regional resources, which are available in a specific region, and can be accessed and used by any availability domain within that region.

Here are detailed explanations of the two regional resources mentioned in the question:

B. Compartments: Compartments are a way to organize and isolate cloud resources in OCI. They are logical containers that enable you to group related resources together and control access to them. Compartments are a regional resource because they exist within a specific region and can be accessed by all availability domains within that region.

By using compartments, you can control access to your resources, monitor usage and costs, and apply policies to enforce security and compliance requirements. You can create compartments within a tenancy and then organize your resources by moving them into the appropriate compartments.

E. Block volume backups: Block volume backups are a way to protect and recover data in OCI. A block volume is a persistent block storage device that can be attached to a compute instance. A block volume backup is a point-in-time copy of the data on a block volume that can be used to restore the volume to a previous state.

Block volume backups are a regional resource because they are stored in a specific region and can be used to recover data within that region. You can create backups on demand or schedule them to occur automatically. You can also copy backups to another region for disaster recovery purposes.

A, C, and D are incorrect because they are not regional resources. Ephemeral public IPs are instance-specific and exist only for the lifetime of the instance. Compute images are global resources that can be used to create instances in any region. Dynamic groups are groups of resources that are used for access control and are not specific to a region.
