.
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. Uses - special processor technology avoid changing system state on privileged instructions - hardware feature are incorporated into processors - more costly
NFS
hardware assist
VMware
virtual machine (VM)
2. An instance of the virtual hardware and the OS that runs on that instance of hardware
virtual machine (VM)
application virtualization
CHAP
VM files
3. 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
benefits of virtualization
VM files
storage virtualization
paravirtulization
4. Network File System
NFS
TCP/IP
configuration file
types of hypervisor
5. 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
binary translation
application virtualization
CHAP
hosted
6. Hosted - binary translation - paravirtualization - hardware assist
benefits of virtualization
host machine
types of hypervisor
hosted
7. Challenge Handshake Authentication Protocol
benefits of virtualization
CHAP
server virtualization
host machine
8. Allows a user to access and run an application hosted on a server as if it were loaded locally on their desktop
application virtualization
hypervisor
NTFS
RAID
9. 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

10. Feature used to get a clean copy of a VM
snapshot
NFS
storage virtualization
CHAP
11. Hypervisor communicates directly with system hardware and assigns individual devices to specific VMs - must contain low level device drivers
VMware
network virtualization
bare-metal
hardware assist
12. 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
