  • 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 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.






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






3. 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.






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






5. An exchange in which a wireless station requests the exclusive right to communicate with an access point and the access point confirms that it has granted that request.






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






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






8. 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.






9. A method used by wireless stations to detect the presence of an access point. The station issues a probe to each channel in its frequency range and waits for the access point to respond.






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






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






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






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






14. Any implementation of UNIX for which the source code is either unavailable or available only by purchasing a licensed copy from Novell (costing as much as millions of dollars).






15. In the context of IPTV - a device that decodes digital video signals and issues them to the television.






16. A collection of H.323 terminals - gateways - and MCUs that are managed by a single H.323 gatekeeper.






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






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






19. A network access method used on 802.11 wireless networks. In it - before a node begins to send data it checks the medium. If it detects no transmission activity - it waits a brief - random amount of time - and then sends its transmission. If the node






20. A variable property associated with a network object. For example - a restriction on the time of day a user can log on is an attribute associated with that user object.






21. The GUI environment for UNIX and Linux systems.






22. In the context of wireless networking - a frame issued by an access point to alert other nodes of its existence.






23. 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






24. A method of multiprocessing that splits all operations equally among two or more processors.






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






26. Another term for the UNIX command interpreter.






27. 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.






28. A logical representation of multiple - hierarchical levels in a directory.






29. A Transport layer protocol used with voice and video transmission. It operates on top of UDP and provides information about packet sequence to help receiving nodes detect delay and packet loss. It also assigns packets a timestamp that corresponds to






30. A UNIX distribution that originated at the University of California at Berkeley.






31. A telephone used for VoIP on a TCP/IP-based network.






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






33. A wireless signaling technique in which a signal jumps between several different frequencies within a band in a synchronization pattern known to the channel's receiver and transmitter.






34. The online documentation for any variety of the UNIX operating system. This documentation describes the use of the commands and the programming interface.






35. A type of WLAN in which stations communicate with an access point and not directly with each other.






36. 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.






37. As specified in RFC 2205 - a QoS technique that attempts to reserve a specific amount of network resources for a transmission before the transmission occurs.






38. A change in a wireless signal's strength as a result of some of the electromagnetic energy being scattered - reflected - or diffracted after being issued by the transmitter.






39. A multiprocessing method that assigns each subtask to a specific processor.






40. A protocol suite codified by the IETF (in RFC 2543) as a set of Session layer signaling and control protocols for multiservice - packet-based networks.






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






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






43. The ability of a processor to perform multiple activities in a brief period of time (often seeming simultaneous to the user






44. A service in which video signals are compressed and delivered over the Internet in a continuous stream so that a user can watch and listen even before all the data has been transmitted.






45. In wireless networking - the process that describes a station moving between BSSs without losing connectivity.






46. The IEEE standard for a wireless networking technique designed to be compatible with 802.11b while using different encoding techniques that allow it to reach a theoretical maximum capacity of 54 Mbps. It uses the 2.4-GHz frequency band.






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






48. The relationship between two domains on a Windows Server 2003 or Server 2008 network that allows a domain controller from one domain to authenticate users from the other domain.






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






50. A connection from an orbiting satellite to an Earth-based receiver.
