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






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






3. Medium dependent interface crossover






4. What is the most common cable used today?






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






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






8. What is used to identify a wireless network?






9. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






11. 568B = Orange - 568A = Green - BOGB = Blue






12. 64-bit encryption level






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






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






15. The standard BOGB cable.






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






17. 568B = Green - 568A = Orange - BOGB = Green






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






19. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






20. 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.






21. Telecommunications Industry Association/Electronics Industries Alliance






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






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






24. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






26. 128-bit encryption level






27. 256-bit encryption level






28. 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






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






30. 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.






31. 100 Mbps






32. Port based network access control (PNAC)






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






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






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






36. The older standard BOGB cable.






37. 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.






38. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






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






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






43. 568B = Brown - 568A = Brown - BOGB = Brown






44. 568B = White/orange - 568A = White/green - BOGB = White/blue






45. 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.






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






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






48. Blue - orange - green and brown.






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






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.
