Which statement is TRUE about restoring a volume from a block volume backup in the Oracle Cloud Infrastructure (OCI) Block Volume service?

When restoring a block volume from a backup in Oracle Cloud Infrastructure (OCI), you have the flexibility to create a new volume that is larger than the original source volume. During the restoration process in the OCI Console or via the API, you can specify a custom size for the new volume. This new size must be equal to or greater than the size of the volume from which the backup was taken. This feature is useful for scenarios where storage requirements have increased since the backup was created.

A. You can restore a volume from both full and incremental backups. The Block Volume service automatically handles the process of reconstructing the full volume at the point-in-time of the selected backup.
C. A single block volume backup can be restored multiple times to create multiple new volumes. There is no inherent limit of one restoration per backup.
D. Block volume backups are stored regionally, not tied to a specific availability domain (AD). This allows you to restore a backup to a new volume in any AD within the same region.

1. Oracle Cloud Infrastructure Documentation, Restoring a Backup to a New Volume:

"If you want to restore the backup to a larger volume, select Specify a custom volume size and then enter the new size. You can only increase the size, you cannot specify a smaller size." This directly supports option B.

The documentation does not impose a limit on the number of restores, invalidating option C.

2. Oracle Cloud Infrastructure Documentation, Overview of Block Volume Backups:

"You can restore a volume from any of your incremental or full backups." This directly refutes option A.

"You can restore a backup to a new volume either in the same availability domain or in another availability domain within the same region." This directly refutes option D.
