SG0-001 · Question #212
Snapshots will provide the ability to recover from which of the following?
The correct answer is B. Users deleting individual files/directories. Snapshots allow recovery from logical data corruption or accidental deletions, such as users deleting individual files or directories, by reverting to a previous point-in-time state of the data.

Why each option
Snapshots allow recovery from logical data corruption or accidental deletions, such as users deleting individual files or directories, by reverting to a previous point-in-time state of the data.
Snapshots do not protect against physical drive failures; RAID (Redundant Array of Independent Disks) is designed to handle such hardware failures.
Snapshots capture the state of data at a specific point in time, enabling recovery of individual files or directories that have been accidentally deleted or corrupted by users since the snapshot was taken. This allows for granular restoration without affecting other data.
Snapshots reside on the same storage array or system as the source data, so a complete array failure would likely destroy both the source data and its snapshots.
If an administrator deletes the source LUN, the associated snapshots for that LUN would also typically be deleted or become inaccessible, as they depend on the existence of the source LUN's metadata.
