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 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.






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






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






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






5. The software that sits between the client and server in a 3-tier architecture.






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






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






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






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






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






11. The brand of computer central processing unit invented by and used in Sun Microsystems servers.






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






13. 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.






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






15. 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






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






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






18. The computer instructions written in a programming language that is readable by humans.






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






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






21. 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.






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






23. An access point that provides routing functions.






24. The brand of computer central processing unit invented by Apple Computer - IBM - and Motorola - Inc. - and used in IBM servers.






25. A standard protocol for accessing network directories.






26. The process of making a disk partition available.






27. 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.|






28. Any type of video service - including IPTV - videoconferencing - and streaming video - that delivers video signals over packet-switched networks using the TCP/IP protocol suite.






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






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






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






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






33. 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






34. The capability for operating multiple logical servers






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






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






37. 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






38. Another term for the UNIX command interpreter.






39. A Session layer control protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for controlling a session between two nodes. For example - it ensures that the two nodes are communicating in the same format.






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






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






42. In the context of wireless networking - the communication that occurs between a station and an access point to enable the station to connect to the network via that access point.






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






44. A series of two or more commands in which the output of prior commands is sent to the input of subsequent commands.






45. 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






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






47. A proprietary implementation of the UNIX system distributed by IBM.






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






49. The characteristic of wireless signals that follow a number of different paths to their destination (for example - because of reflection - diffraction - and scattering).






50. In the context of 802.11n wireless networking - the ability for access points to issue multiple signals to stations - thereby multiplying the signal's strength and increasing their range and data-carrying capacity.
