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 = Orange - 568A = Green - BOGB = Blue






2. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






3. The standard BOGB cable.






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






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






6. 568B = Green - 568A = Orange - BOGB = Green






7. Blue - orange - green and brown.






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






9. 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






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






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






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






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






14. 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.






15. 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?






16. 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.






17. 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.






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






19. 568B = White/brown - 568A = White/brown - BOGB = White/brown






20. 256-bit encryption level






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






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






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






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






25. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






28. 128-bit encryption level






29. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






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






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






33. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






35. Medium dependent interface crossover






36. The older standard BOGB cable.






37. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






38. 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.






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






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






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






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






43. 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.






44. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






47. 64-bit encryption level






48. Regular twisted-pair cabling






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






50. What is used to identify a wireless network?
