What do changes made to resources reserved by a resource pool affect in the resource hierarchy?

A.
Child pools

B.
Host pools

C.
Sibling and parent pools

D.
Root resource pools

Explanation:
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.
In the following example, RP-QA is the parent resource pool for RP-QA-UI. RP-Marketing and RPQA are siblings. The three virtual machines immediately below RP-Marketing are also siblings.
