Which of the following statementabout virtualization is true?

Options

• AVirtualization enables multiple physical computers to run off of a single virtualized server.
• BIn virtualization, you run multiple virtual machines, provided they all use the same operating
• CIn virtualization, the operating systems of the virtual machines should match the host operating

Explanation

Virtualization allows a single physical machine to host multiple virtual machines (VMs), each running its own independent operating system and applications - making D correct. This is the foundational concept: one physical host, many isolated virtual environments.

Why the distractors fail:

• A inverts the relationship - virtualization runs multiple virtual machines on one physical server, not multiple physical machines on one virtual server.
• B is wrong because a key advantage of virtualization is that VMs can run different operating systems simultaneously (e.g., Windows and Linux on the same host).
• C is wrong for the same reason - VMs are isolated from the host OS; a Linux host can run Windows VMs and vice versa.

Memory tip: Think of virtualization as a "one-to-many" relationship - one physical machine, many virtual ones, each with complete OS independence. If an answer suggests limitations on OS variety or flips the physical/virtual relationship, it's wrong.
