Which one of the following descriptions about the memory reuse feature of FusionCompute is wrong?

Which one of the following descriptions about the memory reuse feature of FusionCompute is wrong?
A . After the host memory reuse is enabled, the specific memory reuse degree of the virtual machine can be controlled by the virtual machine memory QoS setting.
B . After the host memory reuse is turned off, the sum of the memory sizes of all virtual machines running on each host cannot be greater than the sum of the actual available physical memory used by the virtual machines
C . After setting the host memory reuse, the total number of virtual machine memory created on the host can exceed the host’s physical memory to increase the host’s virtual machine density
D . Turning off host memory reuse requires that the memory utilization rate of all hosts in the cluster is less than or equal to 150%

Answer: D
