CV0-003 Question #143: Real Exam Question with Answer & Explanation
The correct answer is B: Storage tiering. Storage tiering combines multiple drive technologies (such as FC and SATA) in a single array and uses policy-driven software to automatically move data between performance tiers.
Question
An administrator has been asked by the Chief Information Officer (CIO) to provide storage that will have the ability to accommodate at least FC and SATA in the same enterprise array with software that will be policy driven based on performance. Which of the following enterprise storage features should be recommended?
Options
- AStorage provisioning
- BStorage tiering
- CDynamic provisioning
- DDynamic resource allocation
Explanation
Storage tiering combines multiple drive technologies (such as FC and SATA) in a single array and uses policy-driven software to automatically move data between performance tiers.
Common mistakes.
- A. Storage provisioning refers to the process of allocating and presenting storage capacity to servers or applications and does not address managing or differentiating between multiple drive technologies by performance policy.
- C. Dynamic provisioning (thin provisioning) allocates physical storage blocks on demand as data is written rather than pre-allocating space, which optimizes capacity utilization but does not involve multi-tier drive management.
- D. Dynamic resource allocation is a broad compute and virtualization concept referring to flexible assignment of CPU, memory, or storage resources and is not specific to policy-driven, multi-tier drive technology management within an enterprise array.
Concept tested. Enterprise storage tiering with mixed drive technologies
