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. As specified in RFC 2205 - a QoS technique that attempts to reserve a specific amount of network resources for a transmission before the transmission occurs.






2. 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.






3. 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






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






5. 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






6. A proprietary implementation of the UNIX operating system by Sun Microsystems.






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






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






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






10. A long form of an object's name in Active Directory that explicitly indicates the object name - plus the names of its containers and domains. It includes a DC (domain component) - OU (organizational unit) - and CN (common name).






11. 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.






12. 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.






13. In the context of Windows Server 2003 or Server 2008 - a collection of domain trees that use different namespaces. It allows for trust relationships to be established between trees.






14. A UNIX or Linux file system information storage area that holds all details about a file. This information includes the size - the access rights - the date and time of creation - and a pointer to the actual contents of the file.






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






16. On a SIP network - a server that accepts and responds to requests from user agents and SIP proxy servers for location information on recipients that belong to external domains.






17. 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.






18. 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.






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






20. 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.






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






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






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






24. In IEEE terminology - the identifier for a BSS (basic service set).






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






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






27. The term used to refer to the different implementations of a particular UNIX or Linux system. For example - different distributions of Linux include Fedora - SUSE - and Ubuntu.






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






29. 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.






30. The relative strength over a three-dimensional area of all the electromagnetic energy an antenna sends or receives.






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






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






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






34. A service in which television signals from broadcast or cable networks travel over packet-switched networks.






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






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






37. In the context of wireless networking - the process in which a station listens to several channels within a frequency range for a beacon issued by an access point.






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






39. The name of the primary file system used in most Linux distributions.






40. 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.






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






42. 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.






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






44. A 128-bit number generated and assigned to an object upon its creation in Active Directory.






45. 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






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






47. 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.






48. 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.






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






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