A systems administrator is creating a VM and wants to ensure disk space is not allocated to the VM until it is needed. Which of the following techniques should the administrator use to ensure this?
To ensure that disk space is allocated to the VM only when it is needed, the systems administrator should use thin provisioning. Thin provisioning allows storage to be dynamically allocated on-demand as data is written, rather than reserving and consuming the entire specified disk space upfront. This technique optimizes storage utilization by using space more efficiently and ensuring that disk space is only utilized as it becomes necessary.
Thin provisioning: Specify an initial quantity of available storage capacity, and then set a maximum storage size. The storage grows dynamically up to that maximum size, consuming only what it needs. Thick provisioning: Specify a single quantity of storage capacity that is then reserved for the instance, whether needed or not. Cloud bursting: Configure supplementary public cloud storage for when the organization’s private cloud storage is full.
Thin provisioning= Using resource when needed Thick provisioning = constantly reserving resource
