Why is virtualization important for green IT?

Question

Options

• AVirtualization enables fewer physical servers leaving a smaller footprint and using less power.
• BVirtualization increases network speed and therefore decreases the required hours of processing.
• CVirtualization reduces costs and environmental waste from employees' travel.

• C

Explanation

Virtualization is central to green IT because it allows multiple virtual machines to run on a single physical server, meaning organizations need far fewer physical machines - directly reducing energy consumption, cooling requirements, and hardware waste. Option A is correct because consolidating workloads onto fewer servers is one of the most impactful ways to shrink a data center's carbon and power footprint.

Option B is wrong because virtualization doesn't inherently increase network speed; it optimizes compute resource usage, not transmission bandwidth. Option C is wrong because reducing employee travel is an environmental benefit, but it's associated with remote work/teleconferencing policies - not virtualization technology.

Memory tip: Think "virtual = fewer physical" - every physical server you eliminate saves watts, cooling, and hardware in a landfill. Green IT loves virtualization because less hardware = less power = less waste.
