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 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)






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






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






4. 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.






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






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






7. 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.






8. 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)






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






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






11. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






25. 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.






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






27. 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)






28. 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.






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






30. 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






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






32. 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.






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






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






35. A device used to measure resistance in an electrical circuit.






36. 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.






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






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






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






40. 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.






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






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






43. A document that lists every service and software package supported within an organization - plus the names of first- and second-level support contacts for those services or software packages.






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






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






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






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






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






49. 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.






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