What is a key benefit of server virtualization?

• A. Hardware consolidation and easier management
• B. Increased hardware costs
• C. Longer deployment times
• D. More physical servers required

Answer: (A)

Server virtualization abstracts physical hardware and lets several virtual machines run on a single host through a hypervisor. A key benefit is hardware consolidation and easier management: you can pack many workloads onto fewer physical servers, which lowers data center footprint, power and cooling needs, and licensing costs, while keeping each workload isolated. Centralized management tools and standardized VM templates enable rapid provisioning, consistent configurations, and easier updates or recovery, and you can move VMs between hosts with minimal disruption, boosting agility. The other options don’t fit: virtualization typically lowers costs, speeds up deployment with reusable templates, and reduces, not increases, the number of physical servers needed.
