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 process of making a disk partition available.






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






3. A consortium of companies - including Sony Ericsson - Intel - Nokia - Toshiba - and IBM - that formally banded together in 1998 to refine and standardize Bluetooth technology.






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






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






6. 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






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






8. 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






9. 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






10. 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).






11. The centralized management of multiple types of network-based communications - such as voice - video - fax - and messaging services.






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






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






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






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






16. A file system developed by Microsoft and used with its Windows NT - Windows 2000 Server - Windows Server 2003 - and Windows 2008 operating systems.






17. A network access method used on 802.11 wireless networks. In it - before a node begins to send data it checks the medium. If it detects no transmission activity - it waits a brief - random amount of time - and then sends its transmission. If the node






18. 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.






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






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






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






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






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






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






25. 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.






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






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






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






29. A GUI tool provided with Windows Server 2008 that enables network administrators to manage server roles - features - resources - and users from a single interface.






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






31. 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.






32. 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.






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






34. An operating system's method of organizing - managing - and accessing its files through logical structures and software routines.






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






36. 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.






37. A multiprocessing method that assigns each subtask to a specific processor.






38. An ITU standard that describes an architecture and a suite of protocols for establishing and managing multimedia services sessions on a packet-switched network.






39. A transmission technique in which a signal's bits are distributed over an entire frequency band at once. Each bit is coded so that the receiver can reassemble the original signal upon receiving the bits.






40. A standard protocol for accessing network directories.






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






42. A 128-bit number generated and assigned to an object upon its creation in Active Directory.






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






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






45. A licensing mode that allows a fixed quantity of clients to use one software package simultaneously.






46. 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.






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






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






49. The action of associating a disk - directory - or device with a drive letter.






50. 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.
