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






2. A user account that has unlimited privileges to resources and objects managed by a server or domain.






3. A Session layer call signaling protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for call or videoconference setup between nodes on a VoIP or video-over-IP network - indicating node status - requesting addit






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






5. A standard protocol for accessing network directories.






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






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






8. 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.






9. A pictorial representation of computer functions and elements that - in the case of NOSs - enables administrators to more easily manage files - users - groups - security - printers - and other issues.






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






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






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






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






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






15. 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.|






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






17. In Microsoft terminology - the primary purpose of a Windows Server 2008 server.






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






19. 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.






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






21. 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






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






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






24. An access point that provides routing functions.






25. A continuum of electromagnetic waves used for data and voice






26. 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.






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






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






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






30. 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.






31. A command-line utility for viewing and setting wireless interface parameters on Linux and UNIX workstations.






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






33. 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.






34. The process of copying Active Directory data to multiple domain controllers. This ensures redundancy so that in case one of the domain controllers fails - clients can still log on to the network - be authenticated - and access resources.






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






36. A portion of the kernel that you can load and unload to add or remove functionality on a running UNIX or Linux system.






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






38. 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






39. 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.






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






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






42. A connection from an Earth-based transmitter to an orbiting satellite.






43. 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.






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






45. 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.






46. A type of software license that - for a fixed price - allows any number of users in one location to legally access a program.






47. 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.






48. A streaming video - either on demand or live - that is delivered via the Web.






49. 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.






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