Which virtualization type is installed after an OS is placed on the server?

• A. Type I (Bare Metal)
• B. Type II (Hosted)
• C. Hyper-Converged Infrastructure (HCI)
• D. Emulation

Answer: (B)

Placing the hypervisor on top of an existing operating system defines hosted virtualization. In this setup, the server first has an OS installed, and the virtualization software is installed afterward, running as a program on that host OS. Virtual machines then operate as processes within the host OS environment. This contrasts with bare-metal virtualization, where the hypervisor installs directly on hardware with no host OS, offering different performance characteristics. Hyper-Converged Infrastructure describes an integrated appliance approach, not the specific layering of a hypervisor over an OS. Emulation refers to software that imitates hardware rather than a typical hypervisor deployment model. The scenario described matches hosted virtualization.
