Answer: C

Explanation:

Data Reduction Estimator tool is a command-line host-based utility for estimating the data reduction

saving on block devices.

In order to help with the profiling and analysis of existing user workloads that need to be migrated to a

new system, IBM provides a highly accurate data reduction estimation tool which supports both

deduplicationand compression. The tool operates by scanning target workloads on any legacy storage

array (IBM or 3rd party) and then merging all scan results to provide an integrated system level data

reduction estimate.
