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






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






3. 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).






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






5. A version of Linux packaged and distributed by Red Hat.






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






7. 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.






8. 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.






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






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






11. 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).






12. In the context of 802.11n wireless technology - the combination of two 20-MHz frequency band to create one 40-MHz frequency band that can carry more than twice the amount of data that a single 20-MHz band could. It's recommended for use only in the 5






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






14. 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.






15. 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.






16. The provision of telephone service over a packet-switched network running the TCP/IP protocol suite.






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






18. 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.






19. A connection from an orbiting satellite to an Earth-based receiver.






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






21. 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.






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






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






24. A technique for ensuring QoS by prioritizing traffic.






25. 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.






26. 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.






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






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






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






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






31. A well-defined - self-contained subset of a process. U






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






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






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






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






36. 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






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






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






39. A wireless signal or path that travels directly in a straight line from its transmitter to its intended receiver.






40. The GUI environment for UNIX and Linux systems.






41. The process of moving blocks of information - called pages - between RAM and into a page file on disk.






42. The description of object types - or classes - and their required and optional attributes that are stored in an NOS's directory.






43. In IEEE terminology - a group of stations that share an access point.






44. 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.






45. In the context of wireless networking - a frame issued by an access point to alert other nodes of its existence.






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






47. A type of wireless system in which the receiver can be located anywhere within the transmitter's range. This allows the receiver to roam from one place to another while continuing to pick up its signal.






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






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






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