Which statement about virtual servers is true?

• A. They cannot share hardware
• B. They may be easily scaled depending on application requirements
• C. Only Linux supports virtual servers
• D. They are always slower than dedicated servers

Answer: (B)

Virtual servers are software-defined machines that run on shared physical hardware, with a hypervisor isolating each virtual instance. Because the resources are virtualized, you can adjust CPU, memory, and storage or start additional instances quickly to match what the application needs. This ability to scale up or down as requirements change is the key advantage, so the statement about easy scalability is true.

Think about the other ideas: virtual servers do share hardware because multiple VMs run on the same physical host. They aren’t limited to a single operating system—both Linux and Windows (and others) can host virtual servers. And while there can be some virtualization overhead, they aren’t inherently slower than dedicated servers; performance depends on workload, configuration, and how resources are allocated.
