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






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






4. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






6. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






8. 128- -192- - and 256-bit






9. Telecommunications Industry Association/Electronics Industries Alliance






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






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






12. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






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






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






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






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






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






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






20. 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.






21. The older standard BOGB cable.






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






23. 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?






24. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






27. 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.






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






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






30. 64-bit encryption level






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






32. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






33. Medium dependent interface crossover






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






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






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






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






39. 568B = Orange - 568A = Green - BOGB = Blue






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






41. What is the most common cable used today?






42. 568B = Brown - 568A = Brown - BOGB = Brown






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






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. 10 Mbps






47. Port based network access control (PNAC)






48. Regular twisted-pair cabling






49. 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






50. The standard BOGB cable.
