What type of hypervisor runs directly on physical hardware?

A. Open source
B. Proprietary
C. Type 1
D. Type 2

The correct answer is: C. Type 1

A Type 1 hypervisor, also known as a bare-metal hypervisor, runs directly on the physical hardware of a host machine. This type of hypervisor is installed directly on the physical server without an underlying operating system, which allows it to manage guest virtual machines with high efficiency and performance. Since it communicates directly with the hardware, it can leverage the system's resources more effectively than hypervisors that operate above an OS layer. In contrast, Type 2 hypervisors run on top of an existing operating system, which can introduce overhead and efficiency issues because they must manage two layers of software. The references to open-source and proprietary simply categorize the type of software and do not speak to the architecture in relation to hardware. Hence, while a Type 1 hypervisor refers to a specific architecture that operates directly on hardware, the other options do not correctly capture this critical distinction.
