Which storage efficiency features are available in clustered Data ONTAP 8.2? (choose all that apply)

Thin provisioning allows volumes to present more logical capacity than physically allocated storage, deferring actual disk consumption until data is written and directly reducing storage overhead.

FlexClone creates instant, space-efficient copies by sharing data blocks with the parent volume or LUN, consuming near-zero additional space at creation time.

Deduplication eliminates redundant data blocks stored on disk, reducing the physical space consumed by stored data and is a foundational storage efficiency feature in Data ONTAP.

SnapVault is a disk-to-disk backup and long-term retention feature classified under data protection, not storage efficiency.

Compression encodes stored data more efficiently to reduce its on-disk footprint, directly decreasing physical capacity consumption alongside deduplication.

SyncMirror provides synchronous RAID-level mirroring across disk pools for high availability and is a data protection technology, not a storage efficiency feature.
