    I think A is wrong.
    When you add a host to a drs cluster you can select two case (i’m reading from the wizard):

    – Put all of this hosts’s virtual machine in the cluster’s root resource pool. Resource pools currently present on the host will be deleted.

    – Create a new resourece pool for this host’s virtual machines and resource pools. This preserves the host’s current resource pool hierarchy.

    Only in the first case appears the warning message “Warning: all vapps on the host will be lost”.
    So if you select the first case you lost all pools and vapp in the host and the vm are added to the cluster’s root resource pool.

    If you select the second case, pools and vapps are added to a newly created pool in the cluster’s root resource pool.

    B is the correct answer. I’ve tested this in my dev vCenter, both the RP and vApp are graft when.

    A is wrong because the vApp is not removed.

    hmmm…
    If you add the host by using ‘drag & drop’ instead of ‘Add Host …’ you are not given any options but all VM’s and one vApp were migrated, the RP removed – which makes ‘C’ the correct answer. Tested in my lab.
    seems both B and C are correct – depends how you add the host.

    A is correct. Tricky question! There are 2 resource pools Production pool and Test pool. Does vApp belong to these pool?
