What is a Hypervisor? Types of Hypervisors

Which statement best defines a hypervisor (Virtual Machine Monitor, VMM) in IT?

• A hardware device that accelerates graphics rendering for virtual machines

• A software layer that enables multiple operating systems to run concurrently on a single physical machine

• An operating system designed specifically for cloud servers

• A network appliance that isolates traffic between virtual machines

Type 1 hypervisors are characterized by which of the following?

• They run as an application inside a host operating system

• They run directly on the host hardware, providing a direct interface to the hardware

• They require a separate management OS for networking

• They are only suitable for personal use

Which description fits a Type 2 hypervisor?

• Runs directly on bare-metal hardware

• Provides higher performance and is used in enterprise environments

• Runs as a software application within a host operating system, providing an intermediary layer

• Requires specialized hardware support to boot

Which example is a Type 1 hypervisor?

• Oracle VirtualBox

• VMware Workstation

• VMware ESXi

• Parallels Desktop

Which set of characteristics is most commonly associated with Type 1 hypervisors?

• Runs within a host OS; easier to install and manage; suitable for personal and small business use

• Direct hardware access; higher performance; used in enterprise environments

• Requires an intermediary OS; lower performance; primarily for testing only

• Cloud-only deployment; limited hardware support; no enterprise features

A small business wants quick setup and simple management for running a few virtual machines on existing laptops. Based on the material, which option is most appropriate?

• Deploy a Type 1 hypervisor like KVM for higher performance

• Use a Type 2 hypervisor such as Oracle VirtualBox

• Install VMware ESXi on each laptop for bare‑metal performance

• Avoid virtualization because it is only suitable for enterprises

Which statement best describes Resource Optimization in virtualization?

• Running a single VM on multiple physical servers to increase redundancy

• Allowing multiple virtual machines to share one physical machine’s resources to maximize hardware utilization

• Using dedicated hardware for each VM to avoid resource contention

• Reducing the number of applications installed on a server to save memory

What security advantage does virtualization provide through isolation between virtual machines?

• It guarantees that no VM can ever be compromised

• It prevents malicious software in one VM from affecting other VMs

• It eliminates the need for operating system patches

• It encrypts all network traffic by default

Which benefit of virtualization simplifies disaster recovery procedures?

• Live patching of host operating systems

• Easier replication and migration of virtual machines to different physical machines

• Automatic encryption of storage volumes

• Built-in hardware redundancy for every VM

In virtualization concepts, what is the Guest Operating System?

• The OS running directly on the physical hardware

• The OS that manages resource allocation for all VMs

• The OS running within a virtual machine

• A firmware layer that emulates hardware components
