SG0-001 · Question #49
Which of the following scenarios is the BEST candidate for thin provisioning?
The correct answer is B. Storage utilization patterns that are slow and/or predictable. Thin provisioning is best suited for scenarios where storage consumption patterns are slow and predictable, allowing for efficient, on-demand allocation of physical storage.

Why each option
Thin provisioning is best suited for scenarios where storage consumption patterns are slow and predictable, allowing for efficient, on-demand allocation of physical storage.
Rapidly growing and contracting storage would lead to frequent physical storage allocation and deallocation, potentially reducing the efficiency benefits of thin provisioning.
Thin provisioning allows virtual storage to be presented to applications that is greater than the currently allocated physical storage; this is ideal when storage consumption is slow and predictable, as physical storage can be added incrementally without impacting the application.
High-utilization applications growing simultaneously would likely quickly consume the physical storage, requiring large, sudden additions and negating the 'thin' aspect of provisioning.
Unexpected storage usage patterns make capacity planning difficult, risking over-provisioning or rapid exhaustion of physical storage, which is not ideal for thin provisioning.
