.
Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Allows a user to access and run an application hosted on a server as if it were loaded locally on their desktop
hardware assist
application virtualization
virtual machine (VM)
NFS
2. Transmission Control Protocol/Internet Protocol
virtual machine (VM)
storage virtualization
benefits of virtualization
TCP/IP
3. Reduced cost of hardware and space requirements - rapid deployment and recovery of servers - high availability - separation - and ability to maintain a test environment

CHAP
virtual machine (VM)
automatic software updates
5. Software layer managing hardware requets from guest operating system - also known as virtual machine monitor
bare-metal
host machine
VM files
hypervisor
6. An instance of the virtual hardware and the OS that runs on that instance of hardware
hosted
virtual machine (VM)
hypervisor
server virtualization
7. New Technology File System
bare-metal
automatic software updates
server virtualization
NTFS
8. Hardware that hosts one or more virtual mahcines and shares physical resources with them
CHAP
NFS
host machine
NTFS
9. Consolidate multiple physical servers into virtual servers that run on a single physical server
server virtualization

10. Feature used to get a clean copy of a VM
RAID
hypervisor
application virtualization
snapshot
11. Pooling of physical storage from multiple network storage devices into a single virtual device that is centrally managed
automatic software updates
application virtualization
types of hypervisor
storage virtualization
12. Hypervisor communicates directly with system hardware and assigns individual devices to specific VMs - must contain low level device drivers
bare-metal
NFS
TCP/IP
server virtualization
13. Hypervisor allows some specific system calls to be passed to the physical resources - remaining calls are translated before passing to the physical resource - improved performance - involves modifying the guest OS kernel
hypervisor
paravirtulization
automatic software updates
NTFS
14. Network File System
types of hypervisor
VM files
NFS
hypervisor
15. Hypervisor uses the host OS to run the physcial computer - and manages access to physical resources thru the OS - commonly used on desktops and laptops - can use hardware that the host OS can support
TCP/IP
hosted
VM files
network virtualization
16. Very thin OS below the hypervisor - the hypervisor captures calls for hardware resources and translates the virtual to physical calls - each VM is completely isolated and have the same hardware - commonly used by hosted virtualization
hypervisor
hosted

binary translation
17. Not an advantage of installing virtual machine additions
automatic software updates
server virtualization
benefits of virtualization
configuration file
18. Isolates the VMs from the physical hardware or OS of the host and manages the system calls to the physical resources of the host computer
paravirtulization
hypervisor
hardware assist
storage virtualization
19. Describes the virtual hardware and memory configuration
hypervisor
configuration file
virtual machine (VM)
VMware
20. Combining network resources into a single virtual network which can be independently assigned to different network components
host machine
network virtualization
virtual machine (VM)
hosted
21. A popular virtualization software
VMware
NFS
paravirtulization
TCP/IP
22. Uses - special processor technology avoid changing system state on privileged instructions - hardware feature are incorporated into processors - more costly
