Which two options could be part of the plan to to resolve the issue while minimizing the amount of resources r

Two child resource pools exist for a DRS cluster.

The Production resource pool has been configured with a CPU reservation of 20GHz and a memory reservation of 20GB. The pool has 16 single-processor virtual machines and 4 dual- processor virtual machines. Each of these virtual machines has a CPU reservation of 1GHz and a memory reservation of 1GB.

The Development resource pool and it’s virtual machines have been configured with no reservations. The pool has 1 single-processor virtual machine and 1 dual-processor virtual machine. CPU Shares are set to 4000 and Memory Shares are set to 163840.

The Production team members occasionally complain about the performance of their servers.

Which two options could be part of the plan to to resolve the issue while minimizing the amount of resources reserved by the pool? (Choose two.)

A.
Increase the amount of CPU resources for the Production virtual machines to the processor speed of the host

B.
Set the CPU Shares of Production to 40000

C.
Double the CPU reservation on the Production virtual machines and pool

D.
Set the Memory Shares of Production to 20480

    Well, to me I didn’t even consider A because it makes no sense. The wording does not specify if they are talking about reservation or not. Also, for A to work, Expandable Reservation needs to be enabled, and we do not know that.

    I ruled out D because that would mean the Productoin has less memory shares than Development.

    B is correct because the amount of shares per processor in Prod(40,000/24 = 1667) is better than Dev (4,000/3 = 1333).

    The question asks for 2 so that leaves C. I thought that C could be either true or false given different Proc speeds of the ESX host. So since it COULD be true, I chose it.

  2. Tony says:

    C could be true and is probably the correct answer, but if there is not enough resources to meet the reservations, we won’t be able to power on VMs. VMWare really needs to work on their questions !!!

    I agree Tony. That is where I was stuck with C. You can’t just double the CPU reservations without knowing the total capacity of the vsphere environment.

    But it is the only workable answer left after you cancel A and D
