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 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






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






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






4. 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.






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






6. A type of antenna that issues wireless signals along a single direction - or path.






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






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






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






10. A streaming video - either on demand or live - that is delivered via the Web.






11. A client or server operating system originally developed by researchers at AT&T Bell Laboratories in 1969.






12. 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






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






14. 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.






15. The online documentation for any variety of the UNIX operating system. This documentation describes the use of the commands and the programming interface.






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






17. 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).






18. The process of making a disk partition available.






19. 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






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






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






22. The provision of telephone service over the Internet.






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






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






25. 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.






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






27. The capability for operating multiple logical servers






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






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






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






31. 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.






32. Currently - the most popular version of WiMAX. IEEE improved the mobility and QoS characteristics of the technology - making it better suited to VoIP and mobile phone users.






33. The term used to describe software that is distributed with few restrictions and whose source code is freely available.






34. An access point that provides routing functions.






35. The relative strength over a three-dimensional area of all the electromagnetic energy an antenna sends or receives.






36. 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. |






37. A method of multiprocessing that splits all operations equally among two or more processors.






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






39. The relationship between two domains on a Windows Server 2003 or Server 2008 network that allows a domain controller from one domain to authenticate users from the other domain.
