Which of the following is a common benefit of virtualization in data centers?

• A. Server Consolidation
• B. Increased physical servers
• C. More complex licensing
• D. Longer energy consumption

Answer: (A)

Virtualization lets you run many virtual machines on a single physical server, which leads to server consolidation. By packing multiple workloads onto fewer machines, data centers reduce hardware count, save on capital and maintenance costs, and cut power and cooling needs. This also simplifies management since resources can be allocated and scaled more quickly from a central pool.

The other ideas don’t fit as benefits: adding more physical servers increases costs and space needs, complex licensing is not a benefit and can be a challenge, and longer energy consumption runs counter to the efficiency virtualization aims to achieve.
