Final answer:
Storage VMotion permits the relocation of a virtual machine's data files while it is in use, without any downtime. It allows for live migration of virtual machine storage. Option B is correct.
Step-by-step explanation:
Storage VMotion permits the relocation of the data files that compose a virtual machine while that virtual machine is in use. It is a feature in virtualization environments that allows for live migration of virtual machine storage without any downtime.
During a Storage VMotion operation, the virtual machine's disk files are moved from one storage device to another without interrupting the virtual machine's operation. This is useful for tasks such as load balancing, hardware maintenance, or storage consolidation.
For example, if a virtual machine is running on a storage device that is reaching its capacity, Storage VMotion can be used to move the virtual machine's data files to a different storage device with more available space, all while the virtual machine continues to run. Other options like A) DRS (Distributed Resource Scheduler) and C) Fault Tolerance provide different functionalities. DRS is used for load balancing computing capacity in a cluster of hosts, whereas Fault Tolerance provides continuous availability for a VM by creating and maintaining a secondary VM that is identical to the primary VM.
