A resource pool can contain child resource pools, virtual machines, or both. You can create a hierarchy of shared resources. The resource pools at a higher level are called parent resource pools. Resource pools and virtual machines that are at the same level are called siblings. The cluster itself represents the root resource pool. If you do not create child resource pools, only the root resource pools exist.

    How is this not A?

    The explanation just explains the hierarchy, not how changes affect or do not affect other items int he hierarchy.
    In the graphic above, how does making changes to resources available in RP-QA affect the resources available in RP-Marketing, it’s sibling?

  2. Phil says:

    Because the resource pools all get their available resources from the level above.

    If, for example, you increase or decrease the memory reservation for RP-QA then this will affect the resources available to RP-Marketing because there will be less overall resources available.

      Ok, thanks – that makes sense. That line of thinking had occured to me, but as is usual with these tests, I was thinking somewhat differently than the person who created the question.
