An administrator is configuring a stretched DRS/HA clusters. The administrator wishes to restrict the failover of VMs to certain hosts within a given site.
Winch vSphere feature satisfies this requirement?
A.
DRS Storage Groups
B.
DRS Host Groups
C.
Host Priority
D.
Host Affinity
Explanation:
Ref: Page 73 from vsphere-esxi-vcenter-server-50-resource-management-guide.pdfDRS Host Group is a prerequisite of VM-Host Affinity rule. In DRS group you will create a list of available hosts from specific virtual machines.
Hi, it is not clear to me why isn’t D (Host affinity) a valid option, and from where in the question it is understood that it is being asked for a “prerequisite”. Thanks.

The Answer is D
creating ‘DRS Host Groups’ only will not satisfy requirements of question
and it is clear thing as you cannot create ‘Host Affinity’ with out defining the Host Group

To restrict VMs to certain hosts you need DRS Host groups, DRS VM groups and VM-Host affinity or anti-affinity rules. Hosts groups alone will not “satisfy this requirement” alone.
So I think the correct answer would be ‘DRS Storage groups’ – that’s more general and all three settings are found under that UI.
