Which outcome is commonly achieved by virtualization in data centers?

• A. Server Consolidation
• B. Increased hardware costs
• C. Longer deployment times
• D. Decreased scalability

Answer: (A)

Virtualization focuses on pooling and sharing physical resources by running multiple virtual machines on a single physical server, which makes server consolidation possible. By abstracting hardware, you can host several OSes and applications on one machine, dramatically reducing the number of physical servers needed. This lowers space, power, and cooling requirements and simplifies management, which is why consolidation is the commonly achieved outcome. The other options describe the opposite effects: virtualization typically lowers hardware costs rather than increasing them, speeds up deployment through quick VM provisioning rather than lengthening it, and enhances scalability by allowing dynamic resource allocation rather than reducing it.
