Which type of virtualization involves the host server running virtual machines?

The correct choice is associated with the host server running virtual machines, which is a fundamental aspect of virtualization technologies. In this context, Desktop Virtualization allows users to access a virtual desktop environment that resides on a remote server. This means that multiple virtual desktops can be created and managed within a single host server, enabling users to run different operating systems and applications without being tied to physical hardware limitations.

In Desktop Virtualization, the virtual machines are essentially remote instances that provide a desktop experience similar to that of a local device. This structure enhances efficiency and flexibility in managing user environments, allowing for streamlined updates, security, and management processes.

While other forms of virtualization such as Application, Storage, and Network Virtualization are important in their respective contexts, they do not involve the direct operation of virtual machines by a host server in the same way. For example, Application Virtualization focuses on running applications in isolated environments without requiring the underlying operating system to install or manage them. Storage Virtualization consolidates multiple storage devices into a single logical unit, and Network Virtualization creates a simulated network environment by abstracting the underlying network resources, but they do not utilize the concept of virtual machines in the same way as Desktop Virtualization does.
