In Oracle Cloud Infrastructure (OCI), cross-region access is facilitated by configuring IAM policies that grant users or groups permissions to access resources in other regions. IAM policies in OCI are global, meaning they apply across all regions by default. However, an administrator can specifically configure these policies to allow or restrict access to resources in different regions.

Example:An administrator can write a policy that allows a user to manage compute instances in a specific region by including the region's name in the policy statement.

Restoring a block volume from a backup in OCI provides flexibility and options for scaling and recovery:

Restoring to a Larger Volume Size: When restoring a block volume from a backup, you have the option to restore it to a volume that is larger than the original. This is particularly useful if you anticipate needing more storage capacity after the restore.

Full and Incremental Backups: OCI supports both full and incremental backups. You can restore from any backup type, which makes it possible to restore data efficiently depending on the backup strategy used.

Multiple Restores: Multiple volumes can be restored from a single backup, providing flexibility in disaster recovery scenarios.

Availability Domain: The restored volume can be created in any availability domain within the same region, not necessarily the same one where the original volume was located.

TheInfrequent Access tierin OCI Object Storage is suitable for storing backups that need to be immediately accessible and retained for a specific period, such as 31 days, while also minimizing costs. This tier offers a balance between cost and accessibility, charging lower storage costs compared to the Standard tier but still allowing quick access to the data.

Use Case:The Infrequent Access tier is designed for data that is not frequently accessed but must remain readily available when needed, making it ideal for backup storage.

In OCI File Storage, snapshots are point-in-time, read-only copies of a file system that do not immediately consume additional storage beyond the space needed to track changes.

Incorrect Statement:The statement that a new snapshot consumes more storage even if nothing has changed isincorrect. Snapshots are space-efficient; they only consume additional storage as changes are made to the file system after the snapshot is taken. If no changes are made between snapshots, the storage consumption remains minimal.

Correct Statements:

B.Before cloning a file system, at least one snapshot must exist, as the clone operation relies on this snapshot to create a copy.

C.Snapshots are accessible under the.snapshotdirectory, allowing users to view and restore files from specific snapshots.

D.Snapshots provide a consistent, point-in-time view of the file system, ensuring data integrity.
