Which procedure should the administrator perform to accomplish this task?

A vSphere administrator needs to enable Distributed Resource Scheduling (DRS) in an existing
vSphere environment:
• The environment contains a High Availability (HA) cluster with eight ESXi hosts.
• Six ESXi hosts are not in a cluster.
• DRS should be used on as many hosts as possible.
• Initial placement of virtual machines should be automatically performed.
• Migration recommendations should be provided, but not performed without approval.
Which procedure should the administrator perform to accomplish this task?

A.
Select the datacenter and create a DRS cluster. Add the six remaining hosts to this cluster,
then enable DRS. Edit the DRS settings and change the automation level to Partial.

B.
Select the existing HA cluster. Add the six remaining hosts to the cluster. Enable DRS, then edit
the settings and change the automation level to Manual.

C.
Select the datacenter and create a DRS cluster. Add the six remaining hosts to this cluster,
then enable DRS. Edit the DRS settings and change the automation level to Manual.

D.
Select the existing HA cluster. Add the six remaining hosts to the cluster. Enable DRS, then edit
the settings and change the automation level to Partial.
