FlexCache volumes in clustered ONTAP 8.2 __________.

The correct answer is D. Are sparsely-populated volumes. This question describes the nature of FlexCache volumes in NetApp clustered ONTAP 8.2. FlexCache volumes are characterized by being sparsely-populated, meaning they only store data that has been accessed.

Why each option

This question describes the nature of FlexCache volumes in NetApp clustered ONTAP 8.2. FlexCache volumes are characterized by being sparsely-populated, meaning they only store data that has been accessed.

AAre fully provisioned

FlexCache volumes are not fully provisioned; they populate with data dynamically as it is accessed, rather than pre-allocating all space.

BCan have Snapshot copies

FlexCache volumes cannot have Snapshot copies; Snapshot copies are created and managed exclusively on the origin volume.

CCan be moved

FlexCache volumes cannot be moved between aggregates or nodes within the cluster; their location is tied to the caching node where they are created.

DAre sparsely-populated volumesCorrect

FlexCache volumes in clustered ONTAP 8.2 are sparsely-populated volumes; they only store data blocks that have been requested and read or written through the cache, rather than maintaining a full replica of the origin volume. This design optimizes storage usage by only caching active data.
