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 nonprofit industry association that owns the UNIX trademark.






2. 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






3. The brand of computer central processing unit invented by and used in Sun Microsystems servers.






4. A computer configured to act like an IP telephone. SS7 (Signaling System 7) | A set of standards established by the ITU for handling call signaling on the PSTN (public switched telephone network).






5. 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.






6. In IEEE terminology - a group of stations that share an access point.






7. 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.






8. In the context of Windows Server 2003 or Server 2008 - a collection of domain trees that use different namespaces. It allows for trust relationships to be established between trees.






9. 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.






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






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






12. 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.






13. A well-defined - self-contained subset of a process. U






14. 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.






15. 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.






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






17. The provision of telephone service over the Internet.






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






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






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






21. 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






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






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






24. A proprietary NOS from Apple Computer that is based on a version of UNIX.






25. In the context of wireless networking - the communication that occurs between a station and an access point to enable the station to connect to the network via that access point.






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






27. 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.






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






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






30. The term used to describe the recently released standards for highthroughput - long-distance digital data exchange over wireless connections.






31. 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.






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 proprietary implementation of the UNIX system distributed by IBM.






34. A technique for ensuring QoS by prioritizing traffic.






35. The geographical area in which signals issued from an antenna or wireless system can be consistently and accurately received.






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






37. A group of hierarchically arranged domains that share a common namespace in the Windows Server 2003 or Server 2008 Active Directory.






38. A service that transmits faxes over a TCP/IP network.






39. Another term for the UNIX command interpreter.






40. The memory that is logically carved out of space on the hard drive and added to physical memory (RAM).






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






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






43. 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.






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






45. A group of access points and associated stations (or basic service sets) connected to the same LAN.






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






47. The IEEE standard for a wireless networking technique that may issue signals in the 2.4- or 5-GHz band and can achieve actual data throughput between 65 and 600 Mbps. It accomplishes this through several means - including MIMO - channel bonding - and
