How does system virtualization enhance server efficiency?

• A. By removing the need for physical network connections
• B. By allowing better load balancing across servers
• C. By reducing the number of servers required
• D. By simplifying software development processes

Answer: (C)

System virtualization enhances server efficiency primarily by reducing the number of physical servers required to handle workloads. Virtualization allows multiple virtual machines to run on a single physical server, sharing the underlying hardware resources such as CPU, memory, and storage. This consolidation leads to optimized resource usage, minimizing physical space, energy consumption, and cooling costs associated with managing multiple physical servers.

With virtualization, organizations can effectively deploy multiple operating systems and applications on fewer machines, leading to improved server utilization rates—often well beyond what is achievable with physical servers alone. This efficiency allows for quicker deployment of new services, improved disaster recovery solutions, and better scalability. By decreasing the physical server count, businesses can focus their resources on maintaining and securing fewer systems, ultimately streamlining operations while supporting a more dynamic IT environment.
