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






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






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






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






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






6. Medium dependent interface.






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






8. 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.






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






10. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






11. The older standard BOGB cable.






12. 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.






13. What is the most common cable used today?






14. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






16. Medium dependent interface crossover






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






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






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






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






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






22. 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?






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






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






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






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






27. 128-bit encryption level






28. 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.






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






30. Regular twisted-pair cabling






31. 10 Mbps






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






33. 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.






34. Blue - orange - green and brown.






35. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






37. 128- -192- - and 256-bit






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






39. Port based network access control (PNAC)






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






41. 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.






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






43. 100 Mbps






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






45. 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






46. 568B = Blue - 568A = Blue - BOGB = Orange






47. The standard BOGB cable.






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






49. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.
