Which object-based storage can be used to store virtual machines?

The correct choice is vVols, which stands for Virtual Volumes. vVols is an advanced storage paradigm designed specifically for use with virtualized environments such as VMware vSphere. It allows each virtual machine to have its own storage container, enabling enhanced management and efficient use of storage resources. vVols integrates with the storage array's native capabilities, allowing for functionalities like snapshotting, replication, and provisioning to be managed directly at the VM level.

This design improves scalability and simplifies storage management by allowing the storage policies to be applied at a finer granularity—on a per-VM basis—rather than at the datastore level. It also allows for better alignment between the storage and virtual machine life cycles, making it a robust solution for storing virtual machine data.

In contrast, the other options do have their specific uses in storage management for virtual environments but do not qualify as object-based storage. NFS (Network File System) and VMFS (Virtual Machine File System) are both file-based systems that serve as storage types for virtual machines, while RDM (Raw Device Mapping) provides a way to use a physical disk in a virtual machine context but does not represent a storage paradigm used specifically for object storage. Thus, vVols is the
