Ch 5- Key Terms

Question 1

Hypervisor

Answer 1

Piece of software or hardware that creates and runs a virtual machine and allows multiple operating systems to run on a single physical computer

Question 2

Type 1 hypervisor

Answer 2

Hypervisor that is created and deployed on a bare metal installation

Question 3

Type 2 hypervisor

Answer 3

Hypervisor loaded on top of an already existing operating system installation

Question 4

Open source

Answer 4

Hypervisor software provided at no cost and delivers the same ability to run multiple guest virtual machines on a single host

Question 5

Proprietary

Answer 5

Software that is developed and licensed under an exclusive legal right of the copyright holder

Question 6

Virtualization host

Answer 6

System that hosts or contains guest virtual machines

Question 7

Virtual machine/ guest

Answer 7

Emulates a physical computer where the virtualization host translates requests for compute resources to the underlying physical hardware

Question 8

Basic input/ output system (BIOS)

Answer 8

Built-in software that allows the computer to boot without an operating system and controls the code required to manage the keyboard, display, disk drives, and a number of other functions

Question 9

Firmware

Answer 9

Set of instructions that are programmed for a specific hardware device that instructs the hardware device how to communicate with the computer system

Question 10

Hardware-assisted virtualization

Answer 10

Enables efficient full virtualization used to simulate a complete hardware environment or a virtual machine

Question 11

Central processing unit (CPU)

Answer 11

Hardware device responsible for executing all of the instructions from the operating system and software

Question 12

Virtual CPU (vCPU)

Answer 12

Used on a guest virtual machine and is similar to a physical CPU

Question 13

Network Interface card (NIC)

Answer 13

Computer component that is used to connect a computer to a computer network

Question 14

Virtual NIC (vNIC)

Answer 14

Similar to a physical NIC and has the ability to connect to a virtual switch and be assigned an IP address, default gateway, and subnet mask

Question 15

Virtual disk

Answer 15

Emulates a physical disk drive to a virtual machine

Question 16

Thin provisioning

Answer 16

Allows a virtual disk to allocate and commit storage space on demand and use only the space it currently requires

Question 17

Thick provisioning

Answer 17

Allocates the amount of disk space required when the virtual disk is created

Question 18

Virtual switch

Answer 18

Similar to a physical switch, it allows network devices to be connected and is used to control how the network traffic flows between the virtual machines and the virtualization host

Question 19

Storage virtualization

Answer 19

Groups multiple network storage devices into a single storage unit that can be managed from a central console and presented to a virtual machine or host computer as a single storage unit

Question 20

Guest tools

Answer 20

Software additions that are added to a virtual machine after the operating system has been installed to improve the interaction between the virtual machine and the virtualization host

Question 21

N_Port ID Virtualization (NPIV)

Answer 21

Allows multiple host computers to share a single physical Fibre port identification or N-Port
