VMware memory overcommit

A) A secure site where data communications media converge and are interconnected

B) An allocation method that moves unused memory shares from VMs to other VMs

C) A hardware device that contains multiple tape drives, access ports for tapes and a robotic device for mounting cartridges

D) A way to fit more data on a storage medium by analyzing the data for unique repetitive patterns that can be stored as shorter symbols

Correct Answer : An allocation method that moves unused memory shares from VMs to other VMs

Explanation : Hypervisors allow VMs to use more memory space than the physical host has available. For example, four 1 GB VMs can share a 2 GB host server. VMware enables memory overcommitment with Idle Memory Tax, which assigns a higher value to unused memory shares on a host.
