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. 10 Mbps






2. 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.






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






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






5. Telecommunications Industry Association/Electronics Industries Alliance






6. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






8. The older standard BOGB cable.






9. 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






10. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






11. 568B = Brown - 568A = Brown - BOGB = Brown






12. 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.






13. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






14. 128-bit encryption level






15. 568B = Blue - 568A = Blue - BOGB = Orange






16. Instead of using crossover cables to connect computers to central connecting devices such as switches - these central connecting devices are equipped with _______ ports - which take care of the cross.






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






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






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






20. 64-bit encryption level






21. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






24. 568B = White/orange - 568A = White/green - BOGB = White/blue






25. 568B = Orange - 568A = Green - BOGB = Blue






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






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






28. Blue - orange - green and brown.






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






30. 256-bit encryption level






31. Medium dependent interface crossover






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






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






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






35. 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.






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






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






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






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






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






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






42. 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.






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






44. Occurs when wireless clients connect to and are authenticated by a wireless access point - which can be expanded by creating a wireless distribution system-a group of WAPs interconnected wirelessly.






45. Regular twisted-pair cabling






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






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






48. 568B = White/green - 568A = White/orange - BOGB = White/orange
