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 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.






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






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






4. A UNIX distribution that originated at the University of California at Berkeley.






5. A type of wireless transmission in which signals travel over a single frequency or within a specified frequency range.






6. The provision of telephone service over the Internet.






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






8. 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.|






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






10. The type of multitasking in which tasks are actually performed one at a time - in very brief succession. One program uses the processor for a certain period of time - then is suspended to allow another program to use the processor.






11. An exchange in which a wireless station requests the exclusive right to communicate with an access point and the access point confirms that it has granted that request.






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






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






14. 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






15. 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.






16. 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.






17. A proprietary NOS from Apple Computer that is based on a version of UNIX.






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






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






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






21. The process a wireless station undergoes to find an access point.






22. The GUI environment for UNIX and Linux systems.






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






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






25. 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.






26. A service that runs on a client workstation and determines whether the client's request should be handled by the client or the server.






27. A file on the hard drive that is used for virtual memory.






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






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






30. 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.






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






32. A program (usually text-based) that accepts and executes system programs and applications on behalf of users. Often - it includes the ability to execute a series of instructions that are stored in a file.






33. The term used to describe software that is distributed with few restrictions and whose source code is freely available.






34. 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.






35. A standard protocol for accessing network directories.






36. On a SIP network - a server that accepts requests for location information from user agents - then queries the nearest registrar server on behalf of those user agents. If the recipient user agent is in the SIP proxy server's domain - then that server






37. A form of filename substitution - similar to the use of wildcards in Windows and DOS.






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






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






40. 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.






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






42. A protocol used between media gateway controllers and media gateways. It is poised to replace MGCP on modern converged networks - as it supports a broader range of network technologies - including ATM. Also known as H.248.






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






44. An object in an operating system's directory - such as a printer or user - that does not contain other objects.






45. 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.






46. A device used on wireless LANs that transmits and receives wireless signals to and from multiple nodes and retransmits them to the rest of the network segment. Those can connect a group of nodes with a network or two networks with each other. They ma






47. 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.






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






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






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