What term describes storing data based on performance, cost, and availability in tiers?

• A. RAID
• B. Tiered storage
• C. SSD
• D. Tape drive

Answer: (B)

This describes tiered storage. It groups data into different storage tiers based on how fast the data needs to be accessed, how much a given tier costs, and how available it must be. Data that is accessed frequently sits in a high-performance, more expensive tier; less-active data moves to cheaper, slower tiers. This can be managed automatically in the cloud with lifecycle or tiering policies that migrate data between storage classes or media types as access patterns change. The other options aren’t about organizing data by performance and cost across multiple tiers: RAID is about redundancy and performance within a single system, while SSD and tape drive refer to storage media rather than an organized tiered approach.
