How does virtualization contribute to efficient IT resource utilization?

• A. It eliminates the need for physical servers entirely
• B. It enables running multiple virtual machines on a single physical server, improving utilization and flexibility
• C. It increases hardware costs
• D. It reduces software compatibility

Answer: (B)

Virtualization lets you run several distinct computing environments on one physical server by creating virtual machines. Each VM operates like its own mini-computer with its own operating system and applications, while all share the same underlying hardware resources such as CPU, memory, storage, and networking. This arrangement maximizes hardware use because multiple workloads aren’t tied to separate physical servers; idle capacity on one VM can be allocated to another, reducing wasted resources.

The flexibility comes from being able to deploy, scale, and move VMs quickly. You can resize resources, spin up new environments, or consolidate workloads with minimal downtime, which speeds up IT operations and makes better use of existing hardware.

Although virtualization reduces the number of physical servers needed, it doesn’t eliminate them entirely, and it generally lowers hardware costs rather than increasing them. It also doesn’t inherently reduce software compatibility; in fact, it often helps compatibility by abstracting hardware differences and enabling legacy or diverse environments to run on the same platform.
