  • 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 process a wireless station undergoes to find an access point.






2. The provision of telephone service over a packet-switched network running the TCP/IP protocol suite.






3. 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).






4. In LDAP naming conventions - the name of any one of the domains to which an object belongs.






5. 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.






6. A type of permission - or right - that is passed down from one group (the parent) to a group within that group (the child).






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






8. An operating system's method of organizing - managing - and accessing its files through logical structures and software routines.






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






10. 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.






11. A special identifier shared by BSSs that belong to the same ESS.






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






13. 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






14. A companion protocol to RTP - defined in RFC 3550 by the IETF - RTCP provides feedback on the quality of a call or videoconference to its participants.






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






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






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






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






19. The nerve center for networks that adhere to H.323. IT authorize and authenticate terminals and gateways - manage bandwidth - and oversee call routing - accounting - and billing.






20. The description of object types - or classes - and their required and optional attributes that are stored in an NOS's directory.






21. 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.






22. A technique for ensuring QoS by prioritizing traffic.






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






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






25. A nonprofit industry association that owns the UNIX trademark.






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






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






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






29. The real-time reception and transmission of images and audio among two or more locations.






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






31. 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).






32. Another term for the UNIX command interpreter.






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






34. 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.






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






36. 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.






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






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






39. A Session layer call signaling protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for call or videoconference setup between nodes on a VoIP or video-over-IP network - indicating node status - requesting addit






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






41. A UNIX or Linux file system information storage area that holds all details about a file. This information includes the size - the access rights - the date and time of creation - and a pointer to the actual contents of the file.






42. 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.






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