You have a cluster of FAS controllers with HDD aggregates. The data is being compressed into 32 KB blocks
before being written to a volume.
In this scenario, which type of compression is being used?

A.
secondary, inline compression

B.
adaptive, inline compression

C.
adaptive, postprocess compression

D.
secondary, postprocess compression

Explanation:
NetApp data compression reduces the physical capacity required to store data on storage systems by
compressing data within a flexible volume (FlexVol volume) on primary, secondary, and archive storage. It
compresses regular files, virtual local disks, and LUNs.
When NetApp data compression is configured for inline operation, data is compressed in memory before it is
written to disk.
Incorrect Answers:
C, D: Postprocess compression can compress both recently written data and data that existed on disk prior to
enabling compression.
