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






2. The GUI environment for UNIX and Linux systems.






3. A version of Linux packaged and distributed by Red Hat.






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






5. A service in which a video stored as an encoded file is delivered to a viewer upon his request.






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






7. A routine of sequential instructions that runs until it has achieved its goal.






8. 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.






9. A proprietary implementation of the UNIX operating system by Sun Microsystems.






10. A technique for ensuring QoS by prioritizing traffic.






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






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






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






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






15. A protocol that enables one system to access files on another system.






16. The centralized management of multiple types of network-based communications - such as voice - video - fax - and messaging services.






17. A popular remote file system created by Sun Microsystems - and available for UNIX and Linux operating systems.






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






19. The process of making a disk partition available.






20. A type of antenna that issues and receives wireless signals with equal strength and clarity in all directions. This type of antenna is used when many different receivers must be able to pick up the signal - or when the receiver's location is highly m






21. 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).






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






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






24. 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.






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






26. 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






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






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






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






30. A UNIX command that places files in the printer queue.






31. The name given to the public software project to implement a complete - free source code implementation of UNIX. It also refers to the collection of UNIX-inspired utilities and tools that are included with Linux distributions.|






32. 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.






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






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






35. 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.






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






37. 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.






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






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






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






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






42. Another term for the UNIX command interpreter.






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






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






47. The IEEE standard for a wireless networking technique that uses multiple frequency bands in the 5-GHz frequency range and provides a theoretical maximum throughput of 54 Mbps.






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






49. 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).
