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






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






3. 568B = White/blue - 568A = White/blue - BOGB = White/green






4. Telecommunications Industry Association/Electronics Industries Alliance






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






6. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






7. Similar to a wireless repeater - but the bridge can connect different 802.11 standards together; this is know as bridge mode.






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






9. In order to ensure compatibility - the WAP and other wireless devices must all use the same __________.






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






11. 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.






12. What is the most common cable used today?






13. 568B = Blue - 568A = Blue - BOGB = Orange






14. The older standard BOGB cable.






15. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






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






19. 568B = White/green - 568A = White/orange - BOGB = White/orange






20. What is used to identify a wireless network?






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






22. 128-bit encryption level






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






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






25. A cable with a larger fiber core - capable of carrying multiple rays of light. This type of cable is used for shorter distance runs - up to 600 meters.






26. 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.






27. Occurs when all of the clients communicate directly with each other. There is no base or wireless access point.






28. The sending of two or more frames of data in a single transmission.






29. Medium dependent interface crossover






30. 568B = Orange - 568A = Green - BOGB = Blue






31. Medium dependent interface.






32. 100 Mbps






33. This is a disturbance that can affect electrical circuits - devices - and cables due to electromagnetic conduction and possibly radiation.






34. 568B = White/brown - 568A = White/brown - BOGB = White/brown






35. 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.






36. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






37. When utilizing infrastructure mode - the base unit (normally a WAP) will be configured with a _____________. This then becomes the name of the wireless network - and it is broadcast over the airwaves.






38. If you want to connect a computer directly to another computer without using a switch - you use a _____________.






39. 568B = White/orange - 568A = White/green - BOGB = White/blue






40. To test a cable - what tool would you use?






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






42. 128- -192- - and 256-bit

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






45. Blue - orange - green and brown.






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






47. 256-bit encryption level






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






49. Provides strong authentication to devices that need to connect to the WLAN; it can also be used for regular wired LANs.






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