Identify the two models of storage provisioning.

• A. Thick and Thin
• B. Thick
• C. Thin
• D. Hybrid

Answer: (A)

Storage provisioning models describe how space is allocated to volumes. The two models in question are thick provisioning and thin provisioning. Thick provisioning reserves the entire volume size at creation, so the space is guaranteed and performance is predictable, but this can waste capacity if not fully used. Thin provisioning allocates space on demand, so storage is used more efficiently and you can overcommit relative to physical capacity, though it requires monitoring to avoid running out of space. Hybrid is not the standard provisioning model pair being asked for here; it blends different storage approaches and isn’t the same as the two primary provisioning methods. Therefore, the two models are thick and thin provisioning.
