What is the primary function of vSphere DRS during remediation operations with vSphere Lifecycle Manager?

The primary function of vSphere Distributed Resource Scheduler (DRS) during remediation operations with vSphere Lifecycle Manager is to ensure that workloads are efficiently managed and remain available while updates or patches are applied to ESXi hosts. In this context, DRS is responsible for evacuating virtual machines from the host that is about to be patched or updated.

This evacuation process involves migrating workloads off the host to other available hosts in the cluster to minimize downtime and ensure continuity of service. By doing this, DRS maintains resource availability and performance for running applications, as the physical host being updated can be offlined without impacting the virtual machine availability.

The other options do not accurately represent the core responsibilities of DRS during remediation. DRS does not directly download updates or manage storage, nor does it automatically reconfigure network settings; these tasks are handled by different components within the vSphere infrastructure. Therefore, the effective evacuation of hosts prior to patching is a critical aspect of how DRS supports the overall remediation process.
