Which feature in VMware allows administrators to effectively manage resource allocation for workloads across virtual machines?

Resource Pools are a feature in VMware that allows administrators to effectively manage and allocate resources such as CPU and memory across multiple virtual machines (VMs). This capability provides a way to group VMs that share similar resource requirements or operational characteristics, allowing for more efficient utilization of hardware resources.

By using Resource Pools, administrators can set specific resource limits, reservations, and shares for the VMs contained within the pool. This means that critical VMs can be guaranteed access to resources, while less critical workloads can be limited, thus ensuring that important operations are not starved of the necessary compute resources. Additionally, Resource Pools facilitate the organization of resources in a hierarchical structure, which can help in maintaining clarity and control over resource distribution among different projects or departments within an organization.

In contrast, while the other options listed have their roles in managing various aspects of virtualization, they do not focus specifically on the allocation of CPU and memory resources in the same manner. Datastore Clusters, for instance, manage storage resources rather than compute resources, and vMotion pertains to the live migration of VMs from one host to another without downtime, rather than managing resource allocation. Storage DRS focuses specifically on the management and balancing of storage resources for VMs within datastore clusters. Thus,
