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 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.






2. 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.






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






4. An access point that provides routing functions.






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






6. 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






7. A type of wireless system in which the receiver can be located anywhere within the transmitter's range. This allows the receiver to roam from one place to another while continuing to pick up its signal.






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






9. A device used on wireless LANs that transmits and receives wireless signals to and from multiple nodes and retransmits them to the rest of the network segment. Those can connect a group of nodes with a network or two networks with each other. They ma






10. The process of making a disk partition available.






11. A technique for ensuring QoS by prioritizing traffic.






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






13. 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.






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






15. In the context of 802.11n wireless technology - the combination of two 20-MHz frequency band to create one 40-MHz frequency band that can carry more than twice the amount of data that a single 20-MHz band could. It's recommended for use only in the 5






16. 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.






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






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






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






20. 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.






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






22. A character that enables you to combine existing commands to form new commands.






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






24. A continuum of electromagnetic waves used for data and voice






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






26. In general - a listing that organizes resources and correlates them with their properties. In the context of NOSs - a method for organizing and managing objects.






27. The software that sits between the client and server in a 3-tier architecture.






28. A type of software license that - for a fixed price - allows any number of users in one location to legally access a program.






29. 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).






30. The capability for operating multiple logical servers






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






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






33. In the context of wireless - the phenomenon that occurs when an electromagnetic wave encounters an obstacle and bounces back toward its source.






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






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






36. 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).






37. In LDAP naming conventions - the name of an object.






38. The type of multitasking in which tasks are actually performed one at a time - in very brief succession. One program uses the processor for a certain period of time - then is suspended to allow another program to use the processor.






39. An attribute of an object that identifies the object separately from its related container(s) and domain.






40. 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.






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






42. 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






43. 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.






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






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






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






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






48. A wireless signaling technique in which a signal jumps between several different frequencies within a band in a synchronization pattern known to the channel's receiver and transmitter.






49. 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






50. 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.
