    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.

  2. Mohsin Alvi says:

    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

  3. Rich says:

    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.
