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 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.






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






3. 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.






4. A companion protocol to RTP - defined in RFC 3550 by the IETF - RTCP provides feedback on the quality of a call or videoconference to its participants.






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






6. A standard protocol for accessing network directories.






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






8. The capability for operating multiple logical servers






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






10. 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






11. 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






12. 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






13. A connection from an Earth-based transmitter to an orbiting satellite.






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






15. The RAM chips installed on the computer's system board that provide dedicated memory to that computer.






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






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






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






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






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






21. 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.






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






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






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






25. 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.






26. 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).






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






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






29. A type of trust relationship in which two domains that belong to different NOS directory trees are configured to trust each other.






30. In the context of applications - a licensing mode that limits access to an application to specific users or workstations.






31. 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






32. 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.






33. A service that uses the ATM network access method (and ATM cells) to transmit voice signals over a network.






34. Another term for the UNIX command interpreter.






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






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






37. A means of collectively managing users' permissions and restrictions applied to shared resources.






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






39. A command-line utility for viewing and setting wireless interface parameters on Linux and UNIX workstations.






40. 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.






41. 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.






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






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






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






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






46. A private switch that accepts and interprets both analog and digital voice signals (although some IP-PBXs do not accept analog lines). It can connect with both traditional PSTN lines and data networks. |






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






48. A logical representation of a networked printer's functionality.






49. 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






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