Question

For a typical business, what percentage of data does the ARX usually move to a secondary tier?

Options

A20-30%
B50-60%
C80-90%
D0-10%

Explanation

In a typical enterprise, the vast majority of stored data is inactive or infrequently accessed, making it a candidate for automated tiering to lower-cost secondary storage.

Common mistakes.

A. 20-30% is too low an estimate and does not reflect the typical ratio of inactive to active data found in enterprise environments.
B. 50-60% understates the actual proportion of cold data that ARX typically identifies and migrates in production deployments.
D. 0-10% would imply nearly all data is active, which contradicts the core premise of intelligent tiering and the business case for ARX.

Concept tested. ARX data tiering percentage for secondary storage
