What storage provisioning method is preferred?

• A. Thick
• B. Thin
• C. Eager Zeroed Thick
• D. Lazy Zeroed Thick

Answer: (B)

Thin provisioning is the preferred method because it allocates storage only as data is written, letting many virtual disks share a common pool and grow on demand. This maximizes space utilization, enables overcommitment, and avoids large upfront purchases or wasted capacity. Other provisioning methods reserve space in advance or require heavy upfront zeroing, which can waste time and storage or cause latency on creation; thin provisioning avoids those drawbacks while still allowing monitoring to prevent running out of space.
