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






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






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






4. 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.






5. An access point that provides routing functions.






6. In LDAP naming conventions - the name of any one of the domains to which an object belongs.






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






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






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






10. 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






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






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






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






14. 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.






15. An end node on a network; used most often in the context of wireless networks. transponder






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






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






18. 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.






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






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






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






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






23. 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.






24. 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.






25. 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.






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






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






28. A Windows Server 2003 or Server 2008 computer that contains a replica of the Active Directory database.






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






30. 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






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






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






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






34. A method used by wireless stations to detect the presence of an access point. The station issues a probe to each channel in its frequency range and waits for the access point to respond.






35. 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.






36. The capability for operating multiple logical servers






37. The geographical area in which signals issued from an antenna or wireless system can be consistently and accurately received.






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






39. 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.






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






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






42. In the context of wireless - the phenomenon that occurs when an electromagnetic wave encounters an obstacle and bounces back toward its source.






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






44. 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






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






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






48. 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.






49. The organization of files and directories (or folders) on a disk in which directories may contain files and other directories. When displayed graphically - this organization resembles a treelike structure.






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