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






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






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






4. In 802.11 wireless networking - a type of frame issued by a station during active scanning to find nearby access points.






5. On a network following the H.323 standard - any node that provides audio - visual - or data information to another node.






6. 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.






7. A type of permission - or right - that is passed down from one group (the parent) to a group within that group (the child).






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






9. 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






10. 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.






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






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






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






14. A service in which a video stored as an encoded file is delivered to a viewer upon his request.






15. 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






16. 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.






17. 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.






18. 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.






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






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






21. 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.






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






23. The real-time reception and transmission of images and audio among two or more locations.






24. 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.|






25. 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.






26. The characteristic of wireless signals that follow a number of different paths to their destination (for example - because of reflection - diffraction - and scattering).






27. The GUI environment for UNIX and Linux systems.






28. 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.






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






30. A UNIX service responsible for printing files placed in the printer queue by the lpr command.






31. 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.






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






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






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






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






36. A technique for ensuring QoS by prioritizing traffic.






37. A type of wireless system in which the locations of the transmitter and receiver are static.






38. Any implementation of UNIX for which the source code is either unavailable or available only by purchasing a licensed copy from Novell (costing as much as millions of dollars).






39. A network access method used on 802.11 wireless networks. In it - before a node begins to send data it checks the medium. If it detects no transmission activity - it waits a brief - random amount of time - and then sends its transmission. If the node






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






41. 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.






42. A special identifier shared by BSSs that belong to the same ESS.






43. The IEEE standard for a wireless networking technique that uses DSSS (directsequence spread spectrum) signaling in the 2.4-2.4835-GHz frequency range (also called the 2.4-GHz band). It separates the 2.4-GHz band into 14 overlapping 22-MHz channels an






44. A protocol for communications and resource access between systems - such as clients and servers.






45. A character that enables you to combine existing commands to form new commands.






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






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






48. 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.






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






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