During peak operating hours, an administrator finds that a business-critical application running a virtual machine is not performing as well as during normal hours. Which memory management method can be used to guarantee that the application performs well at all times?
A.
Set a reservation equal to the average memory utilization of the virtual machine running the application.
B.
Set the share level to high for the virtual machine running the application and set the share level for all other virtual machines to low.
C.
Set a limit equal to the peak memory utilization of the virtual machine running the application.
D.
Set the reservation equal to the configured memory of the virtual machine running the application.
Answer should be D. See question 430.
Limit is not useful during normal hours since every VM is competing for the limited physical memory. Reservation however guarantees the memory will be available during normal hour.
