Comptia Network + Network Management And Trouble Shooting

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. Any condition in which voltage exceeds or drops below predefined levels.






2. A GUI application that allows users to easily view and sort events recorded in the event log on a computer running a Windows-based operating system.






3. In network troubleshooting - the person or group who initially fields requests for help from users.






4. A device that tests cables for one or more of the following conditions: continuity - segment length - distance to a fault - attenuation along a cable - near-end cross talk - and termination resistance and impedance.






5. A tool that assesses the characteristics (for example - frequency - amplitude - and the effects of interference) of wireless signals.






6. A technique in which Web pages are stored locally - either on a host or network - and then delivered to requesters more quickly than if they had been obtained from the original source.






7. A small electronic device that emits a tone when it detects electrical activity on a wire pair.






8. A record of how a network operates under normal conditions (including its performance - collision rate - utilization rate - and so on).






9. The local storage of frequently needed files that would otherwise be obtained from an external source.






10. In network troubleshooting - a person or group with deeper knowledge about a subject and to whom first-level support personnel escalate problems.






11. A database used in network management that contains a device's definitions of managed objects and their data.






12. The collection - storage - and assessment of information related to the versions of software installed on every network device and every device's hardware configuration.






13. A correction - improvement - or enhancement to part of a software application - often distributed at no charge by software vendors to fix a bug in their code or to add slightly more functionality.






14. A small electronic device that issues a signal on a wire pair.






15. On a computer running a UNIX or Linux operating system - the record of monitored events - which can range in priority from 0 to 7 (where "0" indicates an emergency situation and "7" simply points to information that might help in debugging a problem)






16. A command-line utility that uses SNMP to poll devices - collects data in a log file - and then generates HTML-based views of the data.






17. A packet that exceeds the medium's maximum packet size. For example - any Ethernet packet that is larger than 1518 bytes.






18. The feature of a network adapter that allows it to pick up all frames that pass over the network






19. The ongoing assessment of how well network links - devices - and components keep up with demands on them.






20. A graphical representation of a network's wired infrastructure.






21. In network troubleshooting - a person or group with deep knowledge about specific networking topics to whom second-level support personnel escalate challenging problems.






22. A software program used to document technical problems and how they were resolved (also known as help desk software).






23. A person who ensures that help desk analysts are divided into the correct teams - schedules shifts at the help desk - and maintains the infrastructure to enable analysts to better perform their jobs.






24. A device used to measure voltage (or electrical pressure) on an electrical circuit.






25. A United States federal regulation that requires telecommunications carriers and equipment manufacturers to provide for surveillance capabilities.






26. A troubleshooting tool that tests cables for continuity - but can also measure cross talk - attenuation - and impedance; identify the location of faults; and store or print cable testing results.






27. A process or program that provides support personnel with a centralized means of documenting changes made to the network.






28. A major change to the existing code in a software application - which may or may not be offered free from a vendor - and may or may not be comprehensive enough to substitute for the original application.






29. A flaw in software or hardware that causes it to malfunction.






30. A device that handles electrical signals improperly - usually affecting the rest of the network. It usually results from a bad NIC.






31. The detection and signaling of device - link - or component faults.






32. A person who's proficient in basic (but not usually advanced) workstation and network troubleshooting. They are part of first-level support.






33. An Application layer protocol in the TCP/ IP suite used to convey data regarding the status of managed devices on a network.






34. A high-end instrument for testing the qualities of a cable. It works by issuing a signal on a cable and measuring the way in which the signal bounces back (or reflects)






35. A network device devoted to storage and delivery of frequently requested files.






36. Another term for the combination of devices known as a tone generator and a tone locator.






37. A tool for accessing and testing a telephone company's local loop.






38. A packet that is smaller than the medium's minimum packet size.






39. A frame that is not actually a data frame - but rather an aberration caused by a device misinterpreting stray voltage on the wire.






40. A graphical representation of a network's devices and connections. network management






41. A software routine that collects data about a managed device's operation and provides it to the network management application running on the console.






42. Manipulating certain characteristics of packets - data streams - or connections to manage the type and amount of traffic traversing a network or interface at any moment.






43. The result of the CRC (cyclic redundancy check) generated by the originating node not matching the checksum calculated from the data received. It usually indicates noise or transmission problems on the LAN interface or cabling.






44. A device that - when plugged into the same outlet that will be used by a network node - gathers data about the power that outlet will provide the node.






45. A network management application's regular collection of data from managed devices.






46. An instrument that tests whether voltage (or light - in the case of fiberoptic cable) issued at one end of a cable can be detected at the opposite end of the cable.






47. A collision that occurs when two or more stations are transmitting simultaneously.






48. A performance testing device for use with fiberoptic networks. It works by issuing a light-based signal on a fiber-optic cable and measuring the way in which the signal bounces back (or reflects)






49. The process of reverting to a previous version of a software application after attempting to upgrade it.






50. A traffic-shaping technique in which the volume or rate of traffic traversing an interface is limited to a predefined maximum.
