What is a primary function of VMware DRS in a cluster environment?

VMware DRS (Distributed Resource Scheduler) plays a crucial role in managing resources within a virtualized environment. Its primary function is to balance workloads by dynamically moving virtual machines (VMs) between hosts in a cluster. This ensures that each host in the cluster is utilized efficiently, preventing overload on individual hosts while optimizing the overall performance of the environment.

When workloads fluctuate or one host becomes heavily utilized while others are underutilized, DRS analyzes resource utilization and automatically reallocates VMs by migrating them to different hosts. This proactive balancing helps maintain performance, increases resource efficiency, and contributes to a more stable environment where VMs can run without disruptions due to resource constraints.

The other choices focus on different aspects of virtualization technology. Offering backup solutions pertains to data protection functions, monitoring hardware health is critical for maintaining infrastructure reliability, and enhancing network security measures involves ensuring the safety and integrity of data and communication. While these are important in a comprehensive IT strategy, they do not represent the core functionality of DRS, which is specifically designed for workload balancing and resource optimization within clustered virtual environments.
