The correct answer is C. Data tiering. The strategy of organizing data across different types of storage, such as SSD, Fibre Channel, and SATA drives, based on its access frequency and performance requirements is known as data tiering.
Question
An administrator would like to employ a strategy to use SAN space more efficiently. Data that has a high I/O and is accessed often should be moved to SSD and Fiber Channel drives while data accessed less often should be moved to the higher capacity SATA drives. Which of the following features describes this strategy?
Options
- ASAN snapshot
- BStorage base lining
- CData tiering
- DCapacity planning

Why each option
The strategy of organizing data across different types of storage, such as SSD, Fibre Channel, and SATA drives, based on its access frequency and performance requirements is known as data tiering.
A SAN snapshot is a point-in-time copy of data used for backup or recovery, not a strategy for optimizing storage utilization based on access patterns.
Storage baselining involves establishing a baseline of normal storage performance and usage, which helps in monitoring but does not describe the act of moving data between different storage types.
Data tiering is the practice of categorizing and placing data on different storage media types (tiers) based on its importance, access frequency, and performance requirements, optimizing both performance and cost.
Capacity planning is the process of forecasting future storage needs and ensuring adequate resources are available, but it does not specifically address the dynamic placement of data based on access patterns to optimize performance and cost.
