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 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).






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






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






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






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






6. 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.






7. 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.






8. An access point that provides routing functions.






9. A service that uses the ATM network access method (and ATM cells) to transmit voice signals over a network.






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






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






12. A type of antenna that issues and receives wireless signals with equal strength and clarity in all directions. This type of antenna is used when many different receivers must be able to pick up the signal - or when the receiver's location is highly m






13. 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






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






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






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






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






18. 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.






19. Another term for the UNIX command interpreter.






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






21. In the context of wireless networking - an assessment of client requirements - facility characteristics - and coverage areas to determine an access point arrangement that will ensure reliable wireless connectivity within a given area.






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






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






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






25. A protocol that enables one system to access files on another system.






26. A Transport layer protocol used with voice and video transmission. It operates on top of UDP and provides information about packet sequence to help receiving nodes detect delay and packet loss. It also assigns packets a timestamp that corresponds to






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






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






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






30. A popular remote file system created by Sun Microsystems - and available for UNIX and Linux operating systems.






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






32. The organization of files and directories (or folders) on a disk in which directories may contain files and other directories. When displayed graphically - this organization resembles a treelike structure.






33. 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






34. A service that relies on a DSL connection to transmit packetized voice signals.






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






36. 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.






37. The term used to describe the recently released standards for highthroughput - long-distance digital data exchange over wireless connections.






38. A group of hierarchically arranged domains that share a common namespace in the Windows Server 2003 or Server 2008 Active Directory.






39. The capability for operating multiple logical servers






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






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






42. 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.






43. 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.






44. 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.
