With Data ONTAP 8.1, which statement is true about deduplication and volume sizes?
The correct answer is D. Deduplication is supported up to the maximum volume size for the platform. In Data ONTAP 8.1, NetApp removed the fixed deduplication volume size cap (which was 16TB in earlier releases) and instead tied deduplication support directly to the maximum volume size allowed by the platform.

Explanation
In Data ONTAP 8.1, NetApp removed the fixed deduplication volume size cap (which was 16TB in earlier releases) and instead tied deduplication support directly to the maximum volume size allowed by the platform. This means that whatever the largest supported volume size is for a given platform (e.g., FAS3000 series, FAS6000 series), deduplication is supported across that entire volume - there is no separate, lower ceiling for deduplication. Options A and B reflect outdated limits from older ONTAP versions, and option C (half the max volume size) was never a real policy.
