MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The most commonly deployed type of hypervisor is the type 1 or bare-metal hypervisor, where virtualization software is installed directly on the hardware where the operating system is normally installed.

Detailed explanation-2: -A bare-metal hypervisor, also known as a Type 1 hypervisor, is virtualization software that has been installed directly onto the computing hardware. This type of hypervisor controls not only the hardware, but one or more guest operating systems (OSes).

Detailed explanation-3: -A Type 1 hypervisor runs directly on the underlying computer’s physical hardware, interacting directly with its CPU, memory, and physical storage. For this reason, Type 1 hypervisors are also referred to as bare-metal hypervisors. A Type 1 hypervisor takes the place of the host operating system.

Detailed explanation-4: -Hyper-V features a Type 1 hypervisor-based architecture. The hypervisor virtualizes processors and memory and provides mechanisms for the virtualization stack in the root partition to manage child partitions (virtual machines) and expose services such as I/O devices to the virtual machines.

Detailed explanation-5: -VMware vSphere / ESXi. The leader in the Tier-1 hypervisors is VMware with their vSphere/ESXi product – available in a free edition and 5 commercial editions. VMware led the market in developing innovative features such as memory overcommitment, vMotion, Storage vMotion, Fault Tolerance, and more.
