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.

5. Used to connect like devices to each other - for example - a computer to another computer - or a switch to another switch.






6. The signal degrades to such a point that it cannot be interpreted by the destination host.






7. Allow for connectivity between a desktop computer or laptop and the wireless access pint.






8. If you are making a crossover cable and one end is 568A - what should the other end be?






9. 568B = White/brown - 568A = White/brown - BOGB = White/brown






10. You are setting up a network within a warehouse using Category 6 UTP. however - parts of the network are down because of the heavy machinery used. What cable type should you use?






11. 10 Mbps






12. 568B = Orange - 568A = Green - BOGB = Blue






13. 568B = Brown - 568A = Brown - BOGB = Brown






14. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






15. You could also use electromagnetic shielding on devices that might be emanating an electromagnetic field. This could be done on a small scale by shielding the single device - or on a larger scale by shielding an entire room - perhaps a server room. T






16. 568B = White/blue - 568A = White/blue - BOGB = White/green






17. Anything that disrupts or modifies a signal that is traveling along a wire.






18. What is the maximum speed supported by 802.11g?






19. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






20. 568B = White/green - 568A = White/orange - BOGB = White/orange






21. What is the most secure encryption used in wireless networks?






22. What is the minimum category of twisted-pair cable you need to support 100 Mbps?






23. What do you call it when electrical signals jump to another set of wires?






24. This means that wireless devices can have more antennas - up to four maximum.






25. Tests all of the pins of a connection one by one.






26. Blue - orange - green and brown.






27. What type of cable should be used as part of a fire code for a building?






28. Port based network access control (PNAC)






29. You need to connect a twisted-pair cable to the back of a patch panel. What tool should you use?






30. When you pick up your wireless phone - your computer drops network connectivity. What could be the cause of the problem?






31. When the signal that is transmitted on one copper wire or pair of wires creates an undesired effect on another wire or pair of wires.






32. What is the most common cable used today?






33. The older standard BOGB cable.






34. Transmits light (photons) instead of electricity - and this light is transmitted over glass or plastic.






35. Regular twisted-pair cabling






36. Telecommunications Industry Association/Electronics Industries Alliance






37. 128-bit encryption level






38. 568B = White/orange - 568A = White/green - BOGB = White/blue






39. Multi-mode fiber (The Medium) - Half duplex: 400 meters; full duplex: 2 km - Single-mode fiber (The Medium) - Full duplex: 10km






40. This is the electromagnetic (EM) field that is generated by a network cable or network device - which can be manipulated to eavesdrop on conversations or to steal data.






41. Occurs when there is measured interference between two pairs in a single cable - measured on the cable end nearest the transmitter.






42. These cables have Teflon coating that makes them more impervious to fire.






43. Which of the following is not a characteristic of 802.11n?






44. Used to extend the coverage of a wireless network.






45. For organizations - using - authentication for wireless networks is recommended.






46. Occurs when there is similar interference - measured at the cable end farthest from the transmitter.






47. A cable with an optical fiber that is meant to carry a single ray of light-one ray of light - one mode. This type of cable is normally used for longer distance runs - generally 10 km and up to 80 km.






48. A network composed of at least one WAP and at least one computer or handheld device that can connect to the WAP.






49. The most common type of patch cable - and it is the type that you would use to connect a computer to a central connecting device like a switch. The wires on each end of the cable are oriented in the same way.






50. 100 Mbps
