Which of the following are benefits of virtual machines (select all that apply)?
  1. Easily test programs on multiple operating systems.
  2. The centralization of physical hardware.
  3. It definitely reduces costs.
  4. They can be hosted on any compute.
Explanation
Answer: A, B - Easily testing programs on multiple operating systems and centralizing physical hardware are two of the benefits of virtual machines.

Key Takeaway: Virtual Machines are exactly what they sound like-virtual machines that run on other physical machines. Hence, you can run three (or even more) virtual machines on one actual system-given that the hardware is powerful enough and compatible with virtualization. For this reason, costs can sometimes still be just as high (and you still have to have a license to the OSes you install).
