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






2. In SIP terminology - end-user devices such as workstations - PDAs - cell phones - or IP telephones. It initiates a SIP connection.






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






4. The preferred Active Directory naming convention for objects when used in informal situations. This name looks like a familiar Internet address - including the positioning of the domain name after the @ sign.






5. A unique character string used to identify an access point on an 802.11 network.






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






7. 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.






8. In Microsoft terminology - a group of interconnected computers that share each others' resources without relying on a central file server.






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






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






11. A service that runs on a client workstation and determines whether the client's request should be handled by the client or the server.






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






13. 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






14. A small (usually home) network composed of personal communications devices.






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






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






17. An object in an operating system's directory - such as a printer or user - that does not contain other objects.






18. An area of a computer's hard drive that is logically defined and acts as a separate disk drive.






19. The signals made of electromagnetic energy that travel through the atmosphere.






20. 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.






21. 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).






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






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






24. A LAN that uses wireless connections for some or all of its transmissions.






25. 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.






26. 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.






27. An access point that provides routing functions and is used as a gateway.






28. 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.






29. A protocol for communications and resource access between systems - such as clients and servers.






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






31. An exchange in which a wireless station requests the exclusive right to communicate with an access point and the access point confirms that it has granted that request.






32. An internal or externally attached adapter that converts analog telephone signals into packet-switched voice signals and vice-versa.






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






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






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






36. The complete database of hierarchical names (including host and domain names) used to resolve IP addresses with their hosts.






37. The proprietary version of UNIX that comes from Bell Labs.






38. A client/server environment that uses middleware to translate requests between the client and server.






39. The method for organizing and managing objects associated with the network in the Windows Server 2003 and Server 2008 NOSs.






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






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






42. A proprietary implementation of the UNIX operating system by Sun Microsystems.






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






44. 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






45. 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.






46. A method used by wireless stations to detect the presence of an access point. The station issues a probe to each channel in its frequency range and waits for the access point to respond.






47. 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.






48. 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.






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






50. 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).
