What are the benefits of configuring a vSphere cluster?

Configuring a vSphere cluster offers several key advantages, particularly in how it enhances resource management, load balancing, and high availability for virtual machines (VMs) within the cluster. When multiple ESXi hosts are joined together in a cluster, VMware vSphere can efficiently manage resources across those hosts, ensuring that each VM has adequate CPU, memory, and storage resources.

Load balancing is particularly important as it distributes workloads evenly across all hosts in the cluster. This prevents any single host from becoming a bottleneck, improving overall performance and reliability. Additionally, the cluster supports high availability, meaning that if one host fails, VMs running on that host can be automatically restarted on another host within the cluster. This redundancy significantly reduces downtime and ensures that services are more resilient.

In contrast, the other options do not accurately capture the primary benefits of configuring a vSphere cluster. While single point management is a feature of vCenter Server rather than specifically a cluster benefit, improved security and automated VM installations are not the central purpose of clustering in vSphere. The primary focus of a vSphere cluster is on resource optimization and availability, which is what makes option B the most relevant and accurate choice.
