VMware vSphere 8.x Professional — Question 57

A vSphere cluster has the following vSphere Distributed Resource Scheduler (DRS) group configuration:
Virtual machine (VM) group named DB
Host groups named PROD11 and PROD55
The administrator wants to force the VMs in the DB group to run on the hosts in the PROD11 group. However, if all the hosts in PROD11 go offline for maintenance, then the VMs in the DB group should run on hosts in PROD55.
Which VM/Host rule must the administrator create to ensure that these requirements are met?

Answer options

• A. A preferential rule between the DB group and the PROD11 group
• B. A preferential rule between the DB group and the PROD55 group
• C. A required rule between the DB group and the PROD11 group
• D. A required rule between the DB group and the PROD55 group

Correct answer: A

Explanation

The correct answer is A because a preferential rule allows the VMs in the DB group to run on the PROD11 hosts first, and if those hosts are unavailable, they can run on the PROD55 hosts. The other options are incorrect because a required rule would not allow the VMs to run on any other hosts if the preferred hosts are offline, which does not meet the stated requirements.
