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.

5. 10 Mbps






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






7. 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?






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






9. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






10. 64-bit encryption level






11. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






13. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






15. Gigabit networks. Has different versions that run at 250 MHz and 500 MHz.






16. Have an aluminum shield inside the plastic jacket that surrounds the pairs of wires.






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






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






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






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






21. 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.






22. Medium dependent interface.






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






24. 568B = Brown - 568A = Brown - BOGB = Brown






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






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






27. 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.






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






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






30. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






31. 568B = Green - 568A = Orange - BOGB = Green






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






33. 256-bit encryption level






34. Telecommunications Industry Association/Electronics Industries Alliance






35. 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.






36. 568B = Blue - 568A = Blue - BOGB = Orange






37. Blue - orange - green and brown.






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






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






40. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






41. What is used to identify a wireless network?






42. Medium dependent interface crossover






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






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






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






46. 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






47. Regular twisted-pair cabling






48. 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.






49. The older standard BOGB cable.






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