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. 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.






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






3. The name given to the public software project to implement a complete - free source code implementation of UNIX. It also refers to the collection of UNIX-inspired utilities and tools that are included with Linux distributions.|






4. 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






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






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






7. 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






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






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






10. In the context of wireless - the phenomenon that occurs when an electromagnetic wave encounters an obstacle and bounces back toward its source.






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






12. The exchange of information between the components of a network or system for the purposes of establishing - monitoring - or releasing connections as well as controlling system operations.






13. 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.






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






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






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






17. On a SIP network - a server that maintains a database containing information about the locations (network addresses) of each user agent in its domain. When a user agent joins a SIP network - it transmits its location information to the SIP registrar






18. The real-time reception and transmission of images and audio among two or more locations.






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






20. 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.






21. 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).






22. 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. |






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






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






25. 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).






26. A service in which a video stored as an encoded file is delivered to a viewer upon his request.






27. A change in a wireless signal's strength as a result of some of the electromagnetic energy being scattered - reflected - or diffracted after being issued by the transmitter.






28. An area covered by a wireless access point that provides visitors with wireless services - including Internet access.






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






30. The ability of a processor to perform multiple activities in a brief period of time (often seeming simultaneous to the user






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






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






33. A variable property associated with a network object. For example - a restriction on the time of day a user can log on is an attribute associated with that user object.






34. The term used to refer to a satellite that maintains a constant distance from a point on the equator at every point in its orbit.






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






36. A form of filename substitution - similar to the use of wildcards in Windows and DOS.






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






38. A wireless signaling technique in which a signal jumps between several different frequencies within a band in a synchronization pattern known to the channel's receiver and transmitter.






39. A program (usually text-based) that accepts and executes system programs and applications on behalf of users. Often - it includes the ability to execute a series of instructions that are stored in a file.






40. 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.






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






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






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






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






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






46. In Microsoft terminology - the type of client/server network that relies on domains - rather than workgroups.






47. The GUI environment for UNIX and Linux systems.






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






49. 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.






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