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






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






3. The older standard BOGB cable.






4. 10 Mbps






5. Blue - orange - green and brown.






6. 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.






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






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






9. 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.






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






11. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






13. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






14. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






15. 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.






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






17. 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






18. 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.






19. 256-bit encryption level






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






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






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






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






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






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






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






27. What is the most common cable used today?






28. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






30. 128-bit encryption level






31. Medium dependent interface crossover






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






33. Telecommunications Industry Association/Electronics Industries Alliance






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






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






36. 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.






37. 568B = Green - 568A = Orange - BOGB = Green






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






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






40. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






41. 568B = Orange - 568A = Green - BOGB = Blue






42. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






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






46. Regular twisted-pair cabling






47. 64-bit encryption level






48. 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.






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






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