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






2. Another term for the UNIX command interpreter.






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






4. A computer configured to act like an IP telephone. SS7 (Signaling System 7) | A set of standards established by the ITU for handling call signaling on the PSTN (public switched telephone network).






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






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






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






8. The complete database of hierarchical names (including host and domain names) used to resolve IP addresses with their hosts.






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






10. 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.






11. An open source software package that provides complete Windows-style file- and printer-sharing capabilities.






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






13. 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.






14. The capability for operating multiple logical servers






15. 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.






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






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






18. 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.






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






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






21. 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.






22. A collection of H.323 terminals - gateways - and MCUs that are managed by a single H.323 gatekeeper.






23. A UNIX command that places files in the printer queue.






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






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 protocol suite codified by the IETF (in RFC 2543) as a set of Session layer signaling and control protocols for multiservice - packet-based networks.






27. 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.






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






29. 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.|






30. A connection from an Earth-based transmitter to an orbiting satellite.






31. 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.






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






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






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






35. A small (usually home) network composed of personal communications devices.






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






37. An internal or externally attached adapter that converts analog telephone signals into packet-switched voice signals and vice-versa.






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






39. 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.






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






41. 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.






42. The RAM chips installed on the computer's system board that provide dedicated memory to that computer.






43. A Session layer call signaling protocol defined as part of ITU's H.323 multiservice network architecture. It is responsible for call or videoconference setup between nodes on a VoIP or video-over-IP network - indicating node status - requesting addit






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






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