.
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. 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
server virtualization
host machine
CHAP
2. An instance of the virtual hardware and the OS that runs on that instance of hardware
TCP/IP
hypervisor
virtual machine (VM)
benefits of virtualization
3. Feature used to get a clean copy of a VM
virtual machine (VM)
snapshot
host machine
TCP/IP
4. 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
paravirtulization
RAID
bare-metal
hypervisor
5. Pooling of physical storage from multiple network storage devices into a single virtual device that is centrally managed
VM files
storage virtualization
network virtualization
benefits of virtualization
6. Redundant Array of Inexpensive Disks
hypervisor
paravirtulization
hardware assist
RAID
7. Uses - special processor technology avoid changing system state on privileged instructions - hardware feature are incorporated into processors - more costly

9. Not an advantage of installing virtual machine additions
automatic software updates
CHAP

VMware
TCP/IP
11. Allows a user to access and run an application hosted on a server as if it were loaded locally on their desktop
types of hypervisor
application virtualization
CHAP
RAID
12. 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
