Several virtual machines residing in a resource pool are exhibiting pools and critical virtual machines in the pool appear hung. The resource pool has been allocated exactly 500MHz of CPU and does not have the option selected. The cluster in which the resource pool resides has a total of 6000MHz, with 1000MHz available.
Which step can be used to increase the performance of the critical?
A.
Increase the CPU limit on the critical virtual machine.
B.
Increase the CPU reservations on the critical virtual mach
C.
Increase the CPU reservations on the resource pool
D.
Increase the CPU limit on the resource pool
Explanation:
Since several critical virtual machines are hung, and if I understand the question didn’t have limit configured (The resource pool has been allocated exactly 500MHz of CPU and does not have the option selected) I choose the option C.
The basic premise is that resource pool reservations are not limits. If the resource pool has been allocated EXACTLY 500 MHz this is a limit not a reservation.

SO the answer is C, correct not D
Critical virtual machine in the resoure pool has been allocated exactly 500MHz of CPU which could not consume 1000MHz of CPU available in the cluster so there is a limit put on this resource pool. And D is correct.
