What is a benefit of using vVols?
- A. All VMs on a datastore are snapped simultaneously.
- B. Individual VMs on a datastore can be snapped.
- C. They enable the automatic import of capability profiles from vSphere to Unisphere.
- D. They enable the assignment of isolated file storage partitions.
Answer: B
Explanation:
Explanation
A benefit of using vVols is that individual VMs on a datastore can be snapped. vVols are virtual volumes that are stored on a storage array and managed by vSphere. They enable granular control and management of VM storage. With vVols, each VM has its own set of virtual disks that are mapped to corresponding storage objects on the array. This allows the array to perform snapshot operations on individual VMs without affecting other VMs on the same datastore.
