The correct answer is A. Fully automated DRS must be enabled on the cluster so that VM1 will be automatically migrated D. VM1 must be manually live migrated to another host within the cluster using vSphere vMotion. To ensure VM1 continues to run during maintenance mode on esx01, the administrator must either enable fully automated DRS for automatic migration or manually live migrate VM1 using vSphere vMotion.

Administrative and Operational Tasks

Question

An administrator is responsible for performing maintenance tasks on a vSphere cluster. The cluster has the following configuration:

  • Identically configured vSphere ESXi hosts (esx01, esx02, esx03 and

esx04)

  • All workloads are deployed into a single VMFS datastore provided by

the external storage array vSphere High Availability (HA) has not been enabled vSphere Distributed Resource Scheduler (DRS) has not been enabled Currently, a critical production application workload (VM1) is running on esx01. Given this scenario, which two actions are required to ensure VM1 continues to run when esx01 is placed into maintenance mode? (Choose two.)

Options

  • AFully automated DRS must be enabled on the cluster so that VM1 will be automatically migrated
  • BVM1 must be manually shut down and cold migrated to another host within the cluster using
  • CvSphere HA must be enabled on the cluster so that VM1 will be automatically migrated to another
  • DVM1 must be manually live migrated to another host within the cluster using vSphere vMotion
  • EVM1 must be manually migrated to another host within the cluster using vSphere Storage vMotion

Why each option

To ensure VM1 continues to run during maintenance mode on esx01, the administrator must either enable fully automated DRS for automatic migration or manually live migrate VM1 using vSphere vMotion.

AFully automated DRS must be enabled on the cluster so that VM1 will be automatically migratedCorrect

Enabling fully automated vSphere Distributed Resource Scheduler (DRS) allows vSphere to automatically live migrate running virtual machines, including VM1, off a host being placed into maintenance mode without downtime.

BVM1 must be manually shut down and cold migrated to another host within the cluster using

Manually shutting down VM1 and cold migrating it would result in downtime, violating the requirement that VM1 continues to run.

CvSphere HA must be enabled on the cluster so that VM1 will be automatically migrated to another

vSphere High Availability (HA) restarts virtual machines on other hosts in case of host failure, but it does not automatically migrate running VMs off a host entering maintenance mode.

DVM1 must be manually live migrated to another host within the cluster using vSphere vMotionCorrect

Since DRS is not enabled, a manual live migration using vSphere vMotion is required to move VM1 from esx01 to another host in the cluster while keeping the application running without interruption during maintenance mode.

EVM1 must be manually migrated to another host within the cluster using vSphere Storage vMotion

vSphere Storage vMotion migrates a VM's disk files between datastores, not the running VM between hosts, which is necessary to move the active workload during host maintenance.
