What type of storage requires a request to increase capacity instead of allowing automatic expansion?

The correct answer is the type of storage that requires a request to increase capacity instead of allowing automatic expansion is indeed non-elastic storage. Non-elastic storage is characterized by its fixed capacity, meaning that once the storage is configured, it does not automatically resize to accommodate additional data. In such systems, if the available space runs out, users must actively request an increase in capacity, often through administrative processes or manual interventions.

In contrast, elastic storage systems are designed to automatically scale up or down according to the storage needs of applications, allowing for more efficient management of resources without user intervention. Static storage, while often thought of as unchanging, does not specifically address the concept of growth requests. Configured storage usually refers to predefined settings and allocations but does not imply a rigidity in capacity that necessitates formal requests for expansion. Therefore, non-elastic is the term that best encapsulates this requirement for administrative action to increase storage capacity.
