Question 17

Chris has learned about a technique that he can configure on some of his virtualized systems to help with memory allocation. Using this specific technique, a driver gets installed on each of the virtual machines on a host. That driver allows the host to control a fake process on the virtual machine so that the VM assigns memory to that process. Rather than actually do something with the memory that has been allocated to the process, the host can then assign that memory to another virtual machine so that it can use the memory instead. Which of the following is the best description of the memory reclamation process that Chris is considering using?

A) Ballooning
B) Overcommitment
C) Bursting
D) Hyperthreading
