Pure Storage Exam FAAA_004 Topic 3 Question 5 Discussion

Why This Matters:

Usable Storage Space Consumed:

The 'usable storage space consumed' refers to the actual physical capacity used on the array after accounting for RAID overhead but before applying data reduction techniques like deduplication and compression.

This value represents the raw space utilized by the data stored on the array, excluding any logical space savings from data reduction.

Why Not the Other Options?

B . 5.58 T:

This value likely represents the logical capacity provisioned or consumed after applying data reduction techniques (e.g., deduplication and compression). However, the question specifically asks for the usable storage space consumed , which excludes logical space savings.

C . 1.22 T:

This value might represent the raw capacity of the drives or some other metric unrelated to the usable storage space consumed. It does not align with the definition of usable storage space.

D . 4.36 T:

This value could represent an intermediate calculation or another metric, but it does not match the usable storage space consumed as shown in the exhibit.

Key Points:

Usable Storage Space Consumed: Represents the physical capacity used on the array after RAID overhead but before data reduction.

Logical vs. Physical Capacity: Logical capacity reflects space savings from deduplication and compression, while usable storage space reflects the actual physical usage.

Exhibit Analysis: Carefully interpret the metrics provided in the exhibit to identify the correct value.
