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. Medium dependent interface crossover






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






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






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






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






6. 100 Mbps






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






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






9. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






10. Telecommunications Industry Association/Electronics Industries Alliance






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






12. Regular twisted-pair cabling






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






14. Port based network access control (PNAC)






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






16. 128- -192- - and 256-bit






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






18. 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.






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






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






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






22. 568B = Brown - 568A = Brown - BOGB = Brown






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






24. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






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






27. 568B = Orange - 568A = Green - BOGB = Blue






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






29. Tests all of the pins of a connection one by one.






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






31. 256-bit encryption level






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






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






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






35. 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.






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






37. 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.






38. The older standard BOGB cable.






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






40. Blue - orange - green and brown.






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






42. 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.






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






44. 568B = Blue - 568A = Blue - BOGB = Orange






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






46. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






47. When the signal that is transmitted on one copper wire or pair of wires creates an undesired effect on another wire or pair of wires.






48. 128-bit encryption level






49. 568B = White/brown - 568A = White/brown - BOGB = White/brown






50. 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
