What happened to the total number of shares provided to a resource pool by the parent pool (%Shares) if a virtual machine is removed from the resource pool?
A.
Remains the same
B.
Decrease
C.
Increases
D.
Decreases
E.
Remains the same if a custom share value was configured. Increases if a high, medium, or low value was configured
See question 390 and 687.
Answer should be D.
Is this really correct,
i created a resource pool added vm’s
check the % share
removed a vm
check the % share
its stayed the same
can someone please expelling hit answer
I believe A is correct.
In http://pubs.vmware.com/vsphere-4-esxi-embedded-vcenter/index.jsp?topic=/com.vmware.vsphere.resourcemanagement.doc_41/managing_resource_pools/c_removing_virtual_machines_from_a_resource_pool.html,
When you remove a virtual machine from a resource pool, the total number of shares associated with the resource pool decreases.
That talks about different things.
Name %Shares
vm1 4000
vm2 4000
vm3 4000
after vm3 is removed, the total number of shares associated with the resource pool decrease from 12000 to 8000.
but the question is if a vm removed from one pool, what happened the %share outside the resource pool.
Remains the same.
I think JAB and runwinged is right, the answer should be A.

When you remove a virtual machine from a resource pool, the total number of shares associated with the resource pool decreases, so that each remaining share represents more resources. For example, assume you have a pool that is entitled to 6GHz, containing three virtual machines with shares set to Normal. Assuming the virtual machines are CPU-bound, each gets an equal allocation of 2GHz. If one of the virtual machines is moved to a different resource pool, the two remaining virtual machines each receive an equal allocation of 3GHz.
D is the correct answer:
You can remove a virtual machine from a resource pool either by moving the virtual machine to another resource pool or deleting it.
When you remove a virtual machine from a resource pool, the total number of shares associated with the resource pool DECREASES, so that each remaining share represents more resources. For example, assume you have a pool that is entitled to 6GHz, containing three virtual machines with shares set to Normal. Assuming the virtual machines are CPU-bound, each gets an equal allocation of 2GHz. If one of the virtual machines is moved to a different resource pool, the two remaining virtual machines each receive an equal allocation of 3GHz.

I tested it in a lab, it was Decreased. all you need is create two pools
drag the VMs around and take look the resource allocation tab of the pool.
Example:
2 pools prod and dev
prod gets 70 %share and dev 30 %share.
you can make changes inside the pool by adding and removing VM’s and the resources will be distributed accordingly but the %share on the “parent pools” stays the same:

A seems to be correct answer.
If you have 2 resource pools with the same share value, each resource pool gets 50% of the resources. If you remove a VM from one of the resource pool, the resource pool still gets 50% of the resources.
Removing the VM decreases the total shares within the resource pool, but not the relationship of shares between the two resource pools.
