When an administrator needs to restore databases provisioned with a shared disk configuration on Windows Storage Spaces in Nutanix Database Service (NDB), the restore operation focuses on the disks associated with the database. Windows Storage Spaces provides a virtualized storage layer, and NDB manages the restoration by reverting or recovering the specific disks that host the database files and logs. This ensures that the database is restored to its previous state using the snapshot or backup data, while preserving the shared disk configuration integrity. NDB does not replace the source volume or perform additional operations like tail log backups unless explicitly configured.
* Option A (NDB restores the disk that are associated with the database) is correct as it accurately describes NDB's restore behavior for shared disk setups.
* Option B (NDB copies the DB files to be restored to the source volume) is incorrect because NDB restores the entire disk state, not just copying files to the source.
* Option C (NDB replaces the source volume with the snapshot volume) is incorrect because NDB restores data to the existing volume, not replacing it entirely.
* Option D (NDB performs Tail Log backup to backup any remaining logs) is incorrect because tail log backups are not automatically part of the restore process unless specified for point-in-time recovery.
This approach ensures compatibility with Windows Storage Spaces configurations.
