Refer to the Exhibit. An administrator is troubleshooting a CPU performance related problem for the SlowVM virtual machine.
Which three actions should the administrator take to improve CPU performance for SlowVM? (Choose three.)
A. Increase the number of vCPUs assigned to SlowVM.
B. Decrease the number of vCPUs assigned to SlowVM.
C. Power off other VMs running on the same ESXi host.
D. Increase the CPU limit for SlowVM.
E. Move SlowVM to another ESXi host with more physical CPU resources available.

Explanation: %CSTP = Excessive usage of vSMP. Decrease amount of vCPUs for this particular VM. This should lead to increased scheduling opportunities.
%CSTP tells you how much time a virtual machine is waiting for a virtual machine with multiple vCPU to catch up. If this number is higher than 3% you should consider lowering the amount of vCPU in your virtual machine.
