Which of the following would be the appropriate technology an administrator would use to provision the desired amount of space to a server, while only the utilized disk space is consumed on the storag

Fat provisioning, or thick provisioning, allocates all the requested logical storage capacity physically from the storage array at the time of provisioning, regardless of actual usage.

Volume groups are logical containers for physical volumes, used in logical volume management (LVM) to group disks, but they do not inherently manage the actual consumption of physical space based on utilization.

Virtual provisioning, commonly referred to as thin provisioning, is a storage allocation method that allows the administrator to oversubscribe storage by presenting a logical volume to a server that is larger than the physically allocated storage. Actual physical disk space is consumed from the storage array only when data is written to the logical volume, enabling efficient use of storage resources.

Concatenated groups combine multiple physical disks or partitions into a single logical volume, but this does not involve allocating space based on utilization; it's about extending volume size.
