Which feature enables load balancing of resources across hosts in a cluster?

• A. DRS
• B. HA
• C. vMotion
• D. vSAN

Answer: (A)

Load balancing across hosts in a cluster is handled by Distributed Resource Scheduler (DRS). DRS continuously monitors CPU and memory usage across all hosts and, when it detects imbalances, automatically migrates virtual machines to different hosts to even out the load. It uses live migration (vMotion) to do this without downtime, so performance stays steady as workloads shift. High Availability focuses on keeping services up after a failure, not proactively balancing load. vMotion is the migration capability itself, not the balancing decision; vSAN is shared storage and doesn’t manage compute resource distribution. So the feature that enables balancing is DRS.
