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 flaw in software or hardware that causes it to malfunction.






2. 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.






3. 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.






4. 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.






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






6. 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.






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






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






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






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






11. 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.






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






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






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






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






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






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






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






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






20. 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.






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






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






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






24. 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.






25. 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






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






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






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






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






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






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






32. 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.






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






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






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






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






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






38. 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.






39. 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.






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






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






42. 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)






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






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






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






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






47. 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)






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






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






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