What capability is achieved by server virtualization?

• A. Increased energy consumption and complexity
• B. More physical servers required
• C. Reduced flexibility and scalability
• D. Hardware consolidation and easier management

Answer: (D)

Server virtualization lets one physical server host multiple isolated virtual servers, pooling hardware resources instead of wasting them on single-purpose machines. This enables hardware consolidation—you can run many virtual machines on fewer physical servers—reducing rack space, energy use, and cooling needs. Management becomes easier because you can deploy, configure, back up, move, and patch all the virtual machines from centralized tools on a single control plane, using standardized images and templates. The other outcomes described would require more physical hardware or add complexity, whereas virtualization aims to streamline infrastructure by consolidating resources and simplifying administration.
