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






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






3. A licensing mode that allows a fixed quantity of clients to use one software package simultaneously.






4. 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.






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






6. A telephone switch used to connect calls within a private organization.






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






8. 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.






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






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






11. A highly privileged user ID that has all rights to create - delete - modify - move - read - write - or execute files on a UNIX or Linux system.






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






13. A companion protocol to RTP - defined in RFC 3550 by the IETF - RTCP provides feedback on the quality of a call or videoconference to its participants.






14. On a SIP network - a server that maintains a database containing information about the locations (network addresses) of each user agent in its domain. When a user agent joins a SIP network - it transmits its location information to the SIP registrar






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 type of wireless transmission in which lower-level signals are distributed over several frequencies simultaneously.






17. A telephone used for VoIP on a TCP/IP-based network.






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






19. A continuum of electromagnetic waves used for data and voice






20. 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.






21. A group of hierarchically arranged domains that share a common namespace in the Windows Server 2003 or Server 2008 Active Directory.






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






23. 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.






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






25. A standard protocol for accessing network directories.






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






27. A version of Linux packaged and distributed by Red Hat.






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






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






30. 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.|






31. 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






32. 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.






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






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






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






36. 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






37. 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.






38. A service in which video signals are compressed and delivered over the Internet in a continuous stream so that a user can watch and listen even before all the data has been transmitted.






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






40. 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.






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






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






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






44. The diffusion of a wireless signal that results from hitting an object that has smaller dimensions compared to the signal's wavelength.






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






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






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






48. 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






49. 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.






50. An access point that provides routing functions and is used as a gateway.
