Instructions:
  • Answer 50 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 LAN that uses wireless connections for some or all of its transmissions.






2. On a network following the H.323 standard - any node that provides audio - visual - or data information to another node.






3. The geographical area in which signals issued from an antenna or wireless system can be consistently and accurately received.






4. A customizable - graphical network management interface introduced with Windows Server 2003 and incorporated in Window Server 2008's Server Manager.






5. In Microsoft terminology - the primary purpose of a Windows Server 2008 server.






6. A file access protocol. It runs over TCP/IP and is the standard file access protocol used by Windows operating systems.






7. In IEEE terminology - the identifier for a BSS (basic service set).






8. A means of collectively managing users' permissions and restrictions applied to shared resources.






9. The name given to the public software project to implement a complete - free source code implementation of UNIX. It also refers to the collection of UNIX-inspired utilities and tools that are included with Linux distributions.|






10. A type of wireless transmission in which signals travel over a single frequency or within a specified frequency range.






11. The IEEE standard for a wireless networking technique that uses multiple frequency bands in the 5-GHz frequency range and provides a theoretical maximum throughput of 54 Mbps.






12. A pictorial representation of computer functions and elements that - in the case of NOSs - enables administrators to more easily manage files - users - groups - security - printers - and other issues.






13. A GUI tool provided with Windows Server 2008 that enables network administrators to manage server roles - features - resources - and users from a single interface.






14. A part of the organizational structure of an operating system's directory that contains objects or other organizational units.






15. A type of wireless system in which the receiver can be located anywhere within the transmitter's range. This allows the receiver to roam from one place to another while continuing to pick up its signal.






16. A continuum of electromagnetic waves used for data and voice






17. A service in which television signals from broadcast or cable networks travel over packet-switched networks.






18. The brand of computer central processing unit invented by Apple Computer - IBM - and Motorola - Inc. - and used in IBM servers.






19. A type of trust relationship in which two domains that belong to different NOS directory trees are configured to trust each other.






20. A wireless signal or path that travels directly in a straight line from its transmitter to its intended receiver.






21. A computer that manages multiple media gateways and facilitates the exchange of call control information between these gateways.






22. A type of satellite that orbits the Earth with an altitude between 100 and 900 miles - closer to the Earth's poles than the orbits of either GEO or MEO satellites.






23. The method for organizing and managing objects associated with the network in the Windows Server 2003 and Server 2008 NOSs.






24. The provision of telephone service over the Internet.






25. In SIP terminology - a server that responds to user agent clients' requests for session initiation and termination.






26. A protocol used between media gateway controllers and media gateways. It is poised to replace MGCP on modern converged networks - as it supports a broader range of network technologies - including ATM. Also known as H.248.






27. On a SIP network - a server that maintains a database containing information about the locations (network addresses) of each user agent in its domain. When a user agent joins a SIP network - it transmits its location information to the SIP registrar






28. A type of wireless transmission in which lower-level signals are distributed over several frequencies simultaneously.






29. A command-line utility for viewing and setting wireless interface parameters on Linux and UNIX workstations.






30. A routine of sequential instructions that runs until it has achieved its goal.






31. In general - a listing that organizes resources and correlates them with their properties. In the context of NOSs - a method for organizing and managing objects.






32. A unique character string used to identify an access point on an 802.11 network.






33. A type of satellite that orbits the Earth roughly 6000 to 12 -000 miles above its surface - positioned between the equator and the poles. These satellites can cover a larger area of the Earth's surface than LEO satellites while using less power and c






34. The action of associating a disk - directory - or device with a drive letter.






35. A logical representation of a networked printer's functionality.






36. A consortium of companies - including Sony Ericsson - Intel - Nokia - Toshiba - and IBM - that formally banded together in 1998 to refine and standardize Bluetooth technology.






37. A type of software license that - for a fixed price - allows any number of users in one location to legally access a program.






38. A file system developed by Microsoft and used with its Windows NT - Windows 2000 Server - Windows Server 2003 - and Windows 2008 operating systems.






39. A domain established within another domain in a Windows Server 2003 or Server 2008 domain tree.






40. A group of hierarchically arranged domains that share a common namespace in the Windows Server 2003 or Server 2008 Active Directory.






41. A telephone switch used to connect calls within a private organization.






42. A type of wireless LAN in which stations communicate directly with each other (rather than using an access point).






43. An internal or externally attached adapter that converts analog telephone signals into packet-switched voice signals and vice-versa.






44. A representation of a thing or person associated with the network that belongs in the NOS directory.






45. A series of two or more commands in which the output of prior commands is sent to the input of subsequent commands.






46. The RAM chips installed on the computer's system board that provide dedicated memory to that computer.






47. A 128-bit number generated and assigned to an object upon its creation in Active Directory.






48. A type of wireless system in which the locations of the transmitter and receiver are static.
