Refer to the Exhibit.
An administrator has deployed a new virtual machine on an ESXi 5.x host. Users are complaining
of poor performance on the application running on the virtual machine. Performance tools display
the results shown in the exhibit.
Which two tasks might improve the user experience? (Choose two.)
A.
Add a vCPU to the virtual machine
B.
Remove CPU affinity on the advanced CPU setting of the virtual machine
C.
Migrate the virtual machine to another ESXi host
D.
Remove the limit on the CPU settings of the virtual machine
I don’t understand; how can you tell there is a CPU limit from the exhibit?

Good question. There doesn’t appear to be any indication that a limit on CPU in in effect.

I think it has to do with a combination of the CPU usage being at 100% and the graph showing a flatline on CPU at the top of the peak. I could be wrong…but I think that’s it.
But the question only asks which two things “could” improve performance. I look at it as a “could be correct” solution.
Also the other two answers can’t be right. CPU affinity is not right, and migrating the VM to another host won’t fix the issue, it’ll just move the problems (resource settings and limits) to another host with the VM.

Look at the CPU realtime graph in the background. It has a plateau at 75% usage but the OS thinks that it is at 100%. Therefore there is a limit in place.
