A. B. C. D.A.
A hypervisor, also known as a virtual machine monitor, is a software layer that allows multiple virtual machines (VMs) to run on a single physical machine. There are two main types of hypervisors: Type 1 and Type 2.
Type 1 hypervisors, also known as native or bare-metal hypervisors, are installed directly on the physical server hardware. They are designed to manage the hardware resources and provide direct access to the underlying hardware for the virtual machines. Examples of Type 1 hypervisors include VMware ESXi, Microsoft Hyper-V, and Citrix Hypervisor.
Type 2 hypervisors, also known as hosted hypervisors, are installed on top of an existing operating system. They run as an application or process within the host operating system and provide a virtualization layer for the virtual machines. Examples of Type 2 hypervisors include Oracle VirtualBox, VMware Workstation, and Parallels Desktop.
VDI, or virtual desktop infrastructure, is a type of technology that allows multiple desktop environments to run on a single server. It is not a type of hypervisor.
A hybrid hypervisor is a type of hypervisor that combines aspects of Type 1 and Type 2 hypervisors. It is installed on top of an existing operating system like a Type 2 hypervisor, but it also has direct access to the underlying hardware like a Type 1 hypervisor. This allows for better performance and security than a traditional Type 2 hypervisor. Examples of hybrid hypervisors include Microsoft Windows Server 2016 Hyper-V and VMware Fusion.
Based on the definitions and explanations above, the correct answer to the question is A. Type 1 hypervisors are physically installed on a server.
