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






2. The older standard BOGB cable.






3. What is used to identify a wireless network?






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






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






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






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






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






9. 568B = Brown - 568A = Brown - BOGB = Brown






10. 64-bit encryption level






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






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






13. 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.






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






15. Port based network access control (PNAC)






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






17. 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.






18. 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.






19. 256-bit encryption level






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






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






22. 568B = Orange - 568A = Green - BOGB = Blue






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






24. The standard BOGB cable.






25. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






26. 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.






27. What is the most common cable used today?






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






29. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






30. Telecommunications Industry Association/Electronics Industries Alliance






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






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






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






34. 568B = White/blue - 568A = White/blue - BOGB = White/green






35. 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






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






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






38. 100 Mbps






39. 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.






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






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






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






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






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






45. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






47. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






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






50. 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?
