What does virtualization enable regarding virtual machines and hardware?

• A. Virtualization enables a virtual machine to operate on different physical hardware.
• B. Virtualization increases the physical size of the server.
• C. Virtualization removes the need for any hardware.
• D. Virtualization is only used for storage devices.

Answer: (A)

Virtualization creates an abstraction layer between the virtual machines and the physical hardware, so each VM sees its own virtual hardware (CPU, memory, storage, network) provided by a hypervisor. Because the VM interacts with virtual hardware rather than directly with physical components, it can run on different physical servers and be moved between hosts with different hardware configurations without changing the guest OS or applications. This portability and decoupling from specific hardware is the core benefit.

The other ideas don’t fit because virtualization doesn’t physically increase server size, it doesn’t remove the need for hardware, and it isn’t limited to storage devices.
