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






2. A group of access points and associated stations (or basic service sets) connected to the same LAN.






3. 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.






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






5. The characteristic of wireless signals that follow a number of different paths to their destination (for example - because of reflection - diffraction - and scattering).






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






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






8. The brand of computer central processing unit invented by Apple Computer - IBM - and Motorola - Inc. - and used in IBM servers.






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






10. 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.






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






12. A type of wireless LAN in which stations communicate directly with each other (rather than using an access point).






13. A type of WLAN in which stations communicate with an access point and not directly with each other.






14. 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.






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






16. In IEEE terminology - the identifier for a BSS (basic service set).






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






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






19. 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.






20. 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.






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






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






23. A freely distributable implementation of a UNIX-type of system. Finnish computer scientist Linus Torvalds originally developed it.






24. A type of satellite that orbits the Earth with an altitude between 100 and 900 miles - closer to the Earth's poles than the orbits of either GEO or MEO satellites.






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






26. The term used to refer to the different implementations of a particular UNIX or Linux system. For example - different distributions of Linux include Fedora - SUSE - and Ubuntu.






27. A type of wireless transmission in which lower-level signals are distributed over several frequencies simultaneously.






28. In the context of wireless signal propagation - the phenomenon that occurs when an electromagnetic wave encounters an obstruction and splits into secondary waves. The secondary waves continue to propagate in the direction in which they were split. Th






29. 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.






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






31. In LDAP naming conventions - the name of any one of the domains to which an object belongs.






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






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






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






35. A portion of the kernel that you can load and unload to add or remove functionality on a running UNIX or Linux system.






36. A Session layer control protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for controlling a session between two nodes. For example - it ensures that the two nodes are communicating in the same format.






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






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






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






40. 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.






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






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






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






44. 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.






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






46. The diffusion of a wireless signal that results from hitting an object that has smaller dimensions compared to the signal's wavelength.






47. 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






48. In wireless networking - the process that describes a station moving between BSSs without losing connectivity.






49. A service in which television signals from broadcast or cable networks travel over packet-switched networks.
