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






2. A transmission technique in which a signal's bits are distributed over an entire frequency band at once. Each bit is coded so that the receiver can reassemble the original signal upon receiving the bits.






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






4. A standard protocol for accessing network directories.






5. An area of a computer's hard drive that is logically defined and acts as a separate disk drive.






6. The signals made of electromagnetic energy that travel through the atmosphere.






7. An access point that provides routing functions and is used as a gateway.






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






9. 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






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






11. 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.






12. A long form of an object's name in Active Directory that explicitly indicates the object name - plus the names of its containers and domains. It includes a DC (domain component) - OU (organizational unit) - and CN (common name).






13. 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.






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






15. An IEEE standard for wireless MANs. Its networks may use frequencies between 2 and 66 GHz. Their antennas may operate in a line-of-sight or non-line-of-sight manner and cover 50 kilometers (or approximately 30 miles). Its connections can achieve a ma






16. A form of filename substitution - similar to the use of wildcards in Windows and DOS.






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






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






19. A logical receptacle for holding objects with similar characteristics or privileges in an NOS directory. Containers form the branches of the directory tree.






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






21. 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.






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






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






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






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






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






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






28. 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.






29. 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.






30. An object in an operating system's directory - such as a printer or user - that does not contain other objects.






31. A type of object recognized by an NOS directory and defined in an NOS schema.






32. 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.






33. A type of satellite Internet access service in which a subscriber sends and receives data to and from the Internet over the satellite link. This is a symmetrical technology - in which both upstream and downstream throughputs are advertised to reach 4






34. 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.






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






36. The provision of telephone service over the Internet.






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






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






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






40. 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






41. The technique of splitting tasks among multiple processors to expedite the completion of any single instruction.






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






43. 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.






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






45. 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.






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






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






48. 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.






49. 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.
