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 record of a user that contains all of her properties - including rights to resources - password - user name - and so on.






2. A cost-savings benefit that results from organizations completing long-distance telephone calls over their packet-switched networks - thus bypassing tolls charged by common carriers on comparable PSTN calls.






3. 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.






4. 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.






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






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






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






8. In the context of 802.11n wireless technology - the combination of two 20-MHz frequency band to create one 40-MHz frequency band that can carry more than twice the amount of data that a single 20-MHz band could. It's recommended for use only in the 5






9. 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.






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






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






12. 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






13. 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.|






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






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






16. 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.






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






18. In Windows Server 2003 or Server 2008 networking - the single domain from which child domains branch out in a domain tree.






19. Another term for the UNIX command interpreter.






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






21. 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.






22. 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






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






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






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






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






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






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






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






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






31. The process of making a disk partition available.






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






33. Currently - the most popular version of WiMAX. IEEE improved the mobility and QoS characteristics of the technology - making it better suited to VoIP and mobile phone users.






34. The relationship between two domains on a Windows Server 2003 or Server 2008 network that allows a domain controller from one domain to authenticate users from the other domain.






35. 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.






36. 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.






37. A routine of sequential instructions that runs until it has achieved its goal.






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






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






40. The IEEE standard for a wireless networking technique designed to be compatible with 802.11b while using different encoding techniques that allow it to reach a theoretical maximum capacity of 54 Mbps. It uses the 2.4-GHz frequency band.






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






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






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






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






45. The core of a UNIX or Linux system. This part of the operating system is loaded and run when you turn on your computer. It mediates between user programs and the computer hardware.






46. A file access protocol. It runs over TCP/IP and is the standard file access protocol used by Windows operating systems.






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






48. 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.






49. 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






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.
