Virtualization

Subject : it-skills
Instructions:
  • Answer 25 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • 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. A popular virtualization software






2. 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






3. New Technology File System






4. Hypervisor communicates directly with system hardware and assigns individual devices to specific VMs - must contain low level device drivers






5. Not an advantage of installing virtual machine additions






6. An instance of the virtual hardware and the OS that runs on that instance of hardware






7. Challenge Handshake Authentication Protocol






8. 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






9. Hosted - binary translation - paravirtualization - hardware assist






10. Allows a user to access and run an application hosted on a server as if it were loaded locally on their desktop






11. Transmission Control Protocol/Internet Protocol






12. Network File System






13. Configuration file and virtual hard drive






14. 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






15. 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






16. Hardware that hosts one or more virtual mahcines and shares physical resources with them






17. Feature used to get a clean copy of a VM






18. Redundant Array of Inexpensive Disks






19. Software layer managing hardware requets from guest operating system - also known as virtual machine monitor






20. Describes the virtual hardware and memory configuration






21. Uses - special processor technology avoid changing system state on privileged instructions - hardware feature are incorporated into processors - more costly






22. Combining network resources into a single virtual network which can be independently assigned to different network components






23. Reduced cost of hardware and space requirements - rapid deployment and recovery of servers - high availability - separation - and ability to maintain a test environment






24. Pooling of physical storage from multiple network storage devices into a single virtual device that is centrally managed






25. Consolidate multiple physical servers into virtual servers that run on a single physical server
