Comptia Network + Wireless NOS Voip

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






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






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






4. The process a wireless station undergoes to find an access point.






5. A UNIX service responsible for printing files placed in the printer queue by the lpr command.






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






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






8. A method of satellite Internet access in which a subscriber receives data via a satellite downlink transmission - but sends data to the satellite via an analog modem (dialup) connection.






9. A logical representation of multiple - hierarchical levels in a directory.






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






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






12. 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.






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






14. In Microsoft terminology - the primary purpose of a Windows Server 2008 server.






15. A group of users - servers - and other resources that share account and security policies through a Windows Server 2003 or Server 2008 NOS.






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






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






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






19. 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.






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






21. 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






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






23. The provision of telephone service over the Internet.






24. The process of making a disk partition available.






25. 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






26. 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.






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






28. As specified in RFC 2205 - a QoS technique that attempts to reserve a specific amount of network resources for a transmission before the transmission occurs.






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






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






31. An access point that provides routing functions.






32. A transmission technique in which a signal's bits are distributed over an entire frequency band at once. Each bit is coded so that the receiver can reassemble the original signal upon receiving the bits.






33. A type of object recognized by an NOS directory and defined in an NOS schema.






34. 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






35. 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.






36. A computer that provides support for multiple H.323 terminals (for example - several workstations participating in a videoconference) and manages communication between them.






37. 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).






38. An open source software package that provides complete Windows-style file- and printer-sharing capabilities.






39. 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.






40. 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.






41. 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.






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






43. 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. |






44. 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.






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






46. A standard protocol for accessing network directories.






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






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






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






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