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






2. A telephone switch used to connect calls within a private organization.






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






4. A wireless networking standard that uses FHSS (frequency hopping spread spectrum) signaling in the 2.4-GHz band to achieve a maximum throughput of either 723 Kbps or 2.1 Mbps - depending on the version. IT was designed for use primarily with small of






5. A cost-savings benefit that results from organizations completing long-distance telephone calls over their packet-switched networks - thus bypassing tolls charged by common carriers on comparable PSTN calls.






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






7. 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.






8. A part of the organizational structure of an operating system's directory that contains objects or other organizational units.






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






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






11. 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.






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






13. In the context of IPTV - a device that decodes digital video signals and issues them to the television.






14. A gateway that can translate IP fax data into analog fax data and vice versa.






15. 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.






16. 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.






17. A type of server on a Windows Server 2003 or Server 2008 network that does not hold directory information and - therefore - cannot authenticate users.






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






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






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






21. A series of two or more commands in which the output of prior commands is sent to the input of subsequent commands.






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






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






24. 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.






25. A technique for ensuring QoS by prioritizing traffic.






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






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






28. 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.






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






30. A file access protocol. It runs over TCP/IP and is the standard file access protocol used by Windows operating systems.






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






32. A licensing mode that allows a fixed quantity of clients to use one software package simultaneously.






33. The computer instructions written in a programming language that is readable by humans.






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






35. 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.






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






37. 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.






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






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






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 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.






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






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






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






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






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






48. 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.






49. 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).






50. A collection of H.323 terminals - gateways - and MCUs that are managed by a single H.323 gatekeeper.
