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. 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.






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






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






4. 128-bit encryption level






5. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






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






9. Blue - orange - green and brown.






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






11. 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.






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






13. The standard BOGB cable.






14. 100 Mbps






15. Telecommunications Industry Association/Electronics Industries Alliance






16. What is the most common cable used today?






17. 568B = Brown - 568A = Brown - BOGB = Brown






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






19. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






22. 64-bit encryption level






23. 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.






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






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






26. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






29. 128- -192- - and 256-bit






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






31. Medium dependent interface crossover






32. 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?






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






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






35. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






36. 568B = White/blue - 568A = White/blue - BOGB = White/green






37. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






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






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






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






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






44. 256-bit encryption level






45. 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.






46. 568B = Orange - 568A = Green - BOGB = Blue






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






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






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






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