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






2. In Windows Server 2003 or Server 2008 networking - the single domain from which child domains branch out in a domain tree.






3. The centralized management of multiple types of network-based communications - such as voice - video - fax - and messaging services.






4. The GUI environment for UNIX and Linux systems.






5. An access point that provides routing functions.






6. A type of phone that includes a screen and can decode compressed video and interpret transport and signaling protocols necessary for conducting videoconference sessions.






7. The name of the primary file system used in most Linux distributions.






8. In the context of wireless networking - the process in which a station listens to several channels within a frequency range for a beacon issued by an access point.






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






10. A cost-savings benefit that results from organizations completing long-distance telephone calls over their packet-switched networks - thus bypassing tolls charged by common carriers on comparable PSTN calls.






11. An ITU standard that describes an architecture and a suite of protocols for establishing and managing multimedia services sessions on a packet-switched network.






12. The term used to refer to the different implementations of a particular UNIX or Linux system. For example - different distributions of Linux include Fedora - SUSE - and Ubuntu.






13. A LAN that uses wireless connections for some or all of its transmissions.






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






15. A computer that provides support for multiple H.323 terminals (for example - several workstations participating in a videoconference) and manages communication between them.






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






17. A program (usually text-based) that accepts and executes system programs and applications on behalf of users. Often - it includes the ability to execute a series of instructions that are stored in a file.






18. A gateway that can translate IP fax data into analog fax data and vice versa.






19. A type of antenna that issues wireless signals along a single direction - or path.






20. 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.






21. A client or server operating system originally developed by researchers at AT&T Bell Laboratories in 1969.






22. The core of a UNIX or Linux system. This part of the operating system is loaded and run when you turn on your computer. It mediates between user programs and the computer hardware.






23. The term used to refer to a satellite that maintains a constant distance from a point on the equator at every point in its orbit.






24. A version of Linux packaged and distributed by Red Hat.






25. An attribute of an object that identifies the object separately from its related container(s) and domain.






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






27. In 802.11 wireless networking - a type of frame issued by a station during active scanning to find nearby access points.






28. A Session layer control protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for controlling a session between two nodes. For example - it ensures that the two nodes are communicating in the same format.






29. The process of moving blocks of information - called pages - between RAM and into a page file on disk.






30. The organization of files and directories (or folders) on a disk in which directories may contain files and other directories. When displayed graphically - this organization resembles a treelike structure.






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






32. On a SIP network - a server that accepts and responds to requests from user agents and SIP proxy servers for location information on recipients that belong to external domains.






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






34. 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.






35. In the context of wireless networking - an assessment of client requirements - facility characteristics - and coverage areas to determine an access point arrangement that will ensure reliable wireless connectivity within a given area.






36. A proprietary implementation of the UNIX operating system by Sun Microsystems.






37. A technique for ensuring QoS by prioritizing traffic.






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






39. A highly privileged user ID that has all rights to create - delete - modify - move - read - write - or execute files on a UNIX or Linux system.






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






41. The process of copying Active Directory data to multiple domain controllers. This ensures redundancy so that in case one of the domain controllers fails - clients can still log on to the network - be authenticated - and access resources.






42. In the DiffServ QoS technique - a forwarding specification that allows routers to assign data streams one of several prioritization levels.






43. A streaming video - either on demand or live - that is delivered via the Web.






44. The software that sits between the client and server in a 3-tier architecture.






45. A Windows Server 2003 or Server 2008 computer that contains a replica of the Active Directory database.






46. In the context of 802.11n wireless technology - the combination of two 20-MHz frequency band to create one 40-MHz frequency band that can carry more than twice the amount of data that a single 20-MHz band could. It's recommended for use only in the 5






47. A type of server on a Windows Server 2003 or Server 2008 network that does not hold directory information and - therefore - cannot authenticate users.






48. A device used on wireless LANs that transmits and receives wireless signals to and from multiple nodes and retransmits them to the rest of the network segment. Those can connect a group of nodes with a network or two networks with each other. They ma






49. In Microsoft terminology - a group of interconnected computers that share each others' resources without relying on a central file server.






50. On a network following the H.323 standard - a gateway that provides translation between network devices running H.323 signaling protocols and devices running other types of signaling protocols (for example - SS7 on the PSTN).
