An administrator wants to prevent a priority virtual machine that resides in a vSphere DRS cluster from migrating to other hosts in the cluster.
What configuration step will accomplish this without affecting other virtual machines?
A. Set VM Overrides to Partially Automated.
B. Set VM Overrides to Manual.
C. Configure a VM/Host Rule with the setting Must run on hosts in group.
D. Configure a VM/Host Rule with the setting Should run on hosts in group.
It seems like A, B, and C – all suitable for this question
A – because VM already exist and if so then DRS will just give recommendation to relocate it but will NOT automatically relocate VM (Partially Automated means VM will be automatically placed only upon creation, but after VM is created then it not be moved by DRS);
B – it’s clear with no comments;
C – we can create hostgroup which contains just one host and VM-group with just one VM. So we can make the rule with “hard” affinity (Must-rule) and it will prevent VM from migrating
I can’t choose right answer
