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






2. 568B = White/green - 568A = White/orange - BOGB = White/orange






3. The standard BOGB cable.






4. 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.






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






6. 64-bit encryption level






7. This is interference that can come from AM/FM transmissions and cell phone towers.






8. 128-bit encryption level






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






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






11. 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?






12. 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.






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






14. 10 Mbps






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






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






17. Port based network access control (PNAC)






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






19. 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.






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






21. What is used to identify a wireless network?






22. 100 Mbps






23. 256-bit encryption level






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






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






26. Has eight wires; they are copper conductors that transmit electric signals. These eight wires are grouped into four pairs: blue - orange - green - and brown.






27. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






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






31. Telecommunications Industry Association/Electronics Industries Alliance






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






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






34. Blue - orange - green and brown.






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






36. 568B = White/brown - 568A = White/brown - BOGB = White/brown






37. What is the maximum speed supported by 802.11b?






38. Medium dependent interface crossover






39. 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.






40. 568B = Brown - 568A = Brown - BOGB = Brown






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






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






43. 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






44. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






45. Regular twisted-pair cabling






46. 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.






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






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






49. 568B = White/blue - 568A = White/blue - BOGB = White/green






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