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






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






3. In network troubleshooting - to refer a problem to someone with deeper knowledge about the subject.






4. 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.






5. 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)






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






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






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






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






10. A collision that takes place outside the normal window in which collisions are detected and redressed. IT usually caused by a defective station (such as a card - or transceiver) that is transmitting without first verifying line status or by failure t






11. A software package or hardware-based tool that can capture and analyze data on a network. It is more sophisticated than network monitoring tools - as they can typically interpret data up to Layer 7 of the OSI model.






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






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






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






15. A significant patch to one of the Microsoft Windows operating systems.






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






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






18. 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)






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






20. 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.






21. The service on Windows-based operating systems that records events - or the ongoing record of such events.






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






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






24. A simple instrument that can measure multiple characteristics of an electric circuit - including its resistance and voltage.






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






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






27. 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.






28. 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.






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






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






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






32. A software-based tool that monitors traffic on the network from a server or workstation attached to the network.






33. 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.






34. 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.






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






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






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






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






39. 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.






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






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






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






43. 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)






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






45. 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.






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






47. 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.






48. The process of identifying and tracking an organization's assets - such as hardware and software.






49. A federal regulation in the United States - enacted in 1996. One aspect of this regulation addresses the security and privacy of medical records - including those stored or transmitted electronically.






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