What is virtualization, and name one benefit in an Army IT environment.

• A. Virtualization runs multiple virtual machines on a single physical host; benefits include reduced hardware, easier testing, faster deployments, and isolation.
• B. Virtualization duplicates hardware; benefits are to increase physical devices.
• C. Virtualization is only used for gaming; not for IT.
• D. Virtualization eliminates the need for operating systems.

Answer: (A)

Virtualization means creating virtual machines that run on a single physical server. Each VM acts like its own computer with its own operating system and applications, all sharing the same hardware resources. In an Army IT environment, a key benefit is reducing the hardware footprint: you can consolidate many servers onto fewer physical machines, cutting costs and power/cooling needs. It also makes testing and deploying new configurations easier and faster because you can quickly clone or template VMs, and it provides isolation between workloads for security and reliability. The other ideas miss what virtualization actually does: it isn’t about duplicating hardware, it isn’t just for gaming, and it doesn’t eliminate the need for operating systems.
