A company provides IaaS services. Which of the following disk provisioning models for creating standard template should the company use to provision virtual instances?

Thin disk provisioning allocates only the storage space that the virtual machine (VM) is actively using, growing dynamically as data is added, up to the configured maximum size. This model is highly efficient for IaaS providers because it allows for storage over-provisioning, meaning they can commit more storage to VMs than they physically possess, optimizing storage utilization and reducing costs.

SCSI (Small Computer System Interface) is a type of interface or bus for connecting storage devices, not a disk provisioning model.

SATA (Serial Advanced Technology Attachment) is a type of interface for connecting storage devices, not a disk provisioning model.

Thick disk provisioning pre-allocates all of the configured storage space at the time of creation, regardless of actual usage, which is inefficient for an IaaS provider due to wasted storage, limiting the number of virtual instances that can be provisioned.
