Answer 28

Data movement across different types of storage based on performance, cost, and access requirements, enhancing storage efficiency.

Question 29

Snapshots vs. Clones

Answer 29

Snapshots are read-only point-in-time images, while clones are writable copies that can be used for testing or development without affecting the original data.

Question 30
