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. The capability for operating multiple logical servers






2. The IEEE standard for a wireless networking technique that uses DSSS (directsequence spread spectrum) signaling in the 2.4-2.4835-GHz frequency range (also called the 2.4-GHz band). It separates the 2.4-GHz band into 14 overlapping 22-MHz channels an






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






4. 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.






5. 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).






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






7. A service that relies on a DSL connection to transmit packetized voice signals.






8. 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.






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






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






11. A connection from an Earth-based transmitter to an orbiting satellite.






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






13. A client/server environment that uses middleware to translate requests between the client and server.






14. An area covered by a wireless access point that provides visitors with wireless services - including Internet access.






15. The term used to describe software that is distributed with few restrictions and whose source code is freely available.






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






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






18. In the context of wireless signal propagation - the phenomenon that occurs when an electromagnetic wave encounters an obstruction and splits into secondary waves. The secondary waves continue to propagate in the direction in which they were split. Th






19. A proprietary implementation of the UNIX system distributed by IBM.






20. The exchange of information between the components of a network or system for the purposes of establishing - monitoring - or releasing connections as well as controlling system operations.






21. An end node on a network; used most often in the context of wireless networks. transponder






22. 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






23. In Microsoft terminology - the type of client/server network that relies on domains - rather than workgroups.






24. In the DiffServ QoS technique - a forwarding specification that assigns each data stream a minimum departure rate from a given node. This technique circumvents delays that slow normal data from reaching its destination on time and in sequence.






25. In the context of wireless networking - the process of a station establishing a connection (or associating) with a different access point.






26. Any type of video service - including IPTV - videoconferencing - and streaming video - that delivers video signals over packet-switched networks using the TCP/IP protocol suite.






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






28. The preferred Active Directory naming convention for objects when used in informal situations. This name looks like a familiar Internet address - including the positioning of the domain name after the @ sign.






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






30. A file on the hard drive that is used for virtual memory.






31. The security relationship between domains in the same domain tree in which one domain grants every other domain in the tree access to its resources and - in turn - that domain can access other domains' resources.






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






33. A service that uses the ATM network access method (and ATM cells) to transmit voice signals over a network.






34. 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






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






36. An open source software package that provides complete Windows-style file- and printer-sharing capabilities.






37. The relative strength over a three-dimensional area of all the electromagnetic energy an antenna sends or receives.






38. 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.






39. 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.






40. 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.






41. The proprietary version of UNIX that comes from Bell Labs.






42. Currently - the most popular version of WiMAX. IEEE improved the mobility and QoS characteristics of the technology - making it better suited to VoIP and mobile phone users.






43. A user account that has unlimited privileges to resources and objects managed by a server or domain.






44. In SIP terminology - end-user devices such as workstations - PDAs - cell phones - or IP telephones. It initiates a SIP connection.






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






46. In the context of 802.11n wireless networking - the ability for access points to issue multiple signals to stations - thereby multiplying the signal's strength and increasing their range and data-carrying capacity.






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






48. A record of a user that contains all of her properties - including rights to resources - password - user name - and so on.






49. A protocol used for communication between media gateway controllers and media gateways.






50. An access point that provides routing functions.
