Question

What software allows you to define VMs and manage resource allocation and sharing among them on a host computer?

A. Hypervisor
B. NVF (Network Functions Virtualizations)
C. SDN (software-defined technology)
D. Terminal Emulation

Answer 1

A hypervisor is the software that allows you to define VMs and manage resource allocation and sharing among them on a host computer.

Step-by-step explanation:

The software that allows you to define VMs (Virtual Machines) and manage resource allocation and sharing among them on a host computer is called a Hypervisor. A hypervisor is a type of software that enables the creation, execution, and management of virtual machines.

There are two types of hypervisors:

1. Type 1 Hypervisor: This runs directly on the host machine's hardware and manages the virtual machines without the need for an underlying operating system. Examples of Type 1 hypervisors include VMware ESXi and Microsoft Hyper-V.
2. Type 2 Hypervisor: This runs on top of an existing operating system and manages the virtual machines as processes. Examples of Type 2 hypervisors include Oracle VirtualBox and VMware Workstation.

By using a hypervisor, you can create and manage multiple virtual machines on a single physical server, allowing for efficient resource utilization and isolation among the VMs.
