Which of the following resources can be managed using resource pools?
A.
Memory
B.
Network
C.
I/O
D.
Disk
Explanation:
A resource pool is a logical abstraction for flexible management of resources. Resource pools can be grouped into hierarchies and used to hierarchically partition available CPU and memory resources.
VCP4 question, vSphere 5 newly supports Network Resource Pools if Network I/O Control is enabled, see http://pubs.vmware.com/vsphere-50/topic/com.vmware.vsphere.networking.doc_50/GUID-ADEA0213-C969-43E4-B1F4-66D4A916EBDF.html
(But note that Network Resource Pools work quite differently than classic Memory+CPU resource pools.)
