Which statement about virtual machines is true?

• A. Each virtual machine appears to the user as a separate, independent computer with its own operating system.
• B. They all share the same OS and resources without isolation
• C. They require no network access
• D. They cannot run different operating systems

Answer: (A)

Virtual machines are software-based computers that run on a physical host through a hypervisor. Each VM has its own virtual hardware and can boot its own operating system, so to the user it looks like a separate, independent computer. This isolation lets you run different operating systems on the same host, such as Windows on one VM and Linux on another, at the same time. That’s why the statement about each virtual machine appearing as a separate computer with its own OS is true. The other options miss how virtualization works: VMs do provide isolation and can share host resources, but they don’t all share a single OS; they can have network access depending on configuration; and they can indeed run different operating systems.
