Thick provisioning refers to reserving the full allocated storage space upfront.

• A. Thin provisioning
• B. Thick provisioning
• C. Dynamic provisioning
• D. Incremental provisioning

Answer: (B)

Thick provisioning means reserving the entire allocated storage space at the moment the volume is created. When you set aside a fixed size, that full amount becomes unavailable to other volumes, even if you don’t use it all yet. This guarantees space is always available for that volume and offers predictable performance, but it can waste storage if the full size isn’t actually used. The other provisioning approaches allocate space on demand or in smaller increments, which improves utilization but can lead to space contention if actual usage grows faster than anticipated.
