Which vSphere feature protects against host hardware failures by restarting virtual machines (VMs) on hosts?

The feature that protects against host hardware failures by restarting virtual machines (VMs) on other available hosts is vSphere HA, or High Availability. This feature is designed to monitor all the virtual machines within a cluster and the underlying hosts. In the event of a host failure, vSphere HA automatically restarts the affected VMs on other functioning hosts within the cluster, minimizing downtime and providing a level of resilience against hardware failures.

vSphere HA is essential for maintaining business continuity, as it ensures that applications remain available even if a physical server fails. It's particularly useful in environments where uptime is critical, as it automates the recovery process without requiring manual intervention.

The other options serve different purposes. vSphere vMotion is focused on live migrating VMs from one host to another without downtime but does not address hardware failures specifically. vSphere Fault Tolerance provides a continuous availability mechanism by creating a live shadow instance of a VM but does not handle the situation where the host fails; it instead relies on having another host ready to take over the workload immediately. vSphere DRS (Distributed Resource Scheduler) optimizes resource usage across hosts in a cluster but does not recover VMs from host failures.

Thus, vSphere HA is the correct answer as it directly
