Wired And Wireless Networks

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






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






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






4. 128-bit encryption level






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






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






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






8. The older standard BOGB cable.






9. 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.






10. 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






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






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






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






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






15. 256-bit encryption level






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






17. 568B = Brown - 568A = Brown - BOGB = Brown






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






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






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






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






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






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






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






25. The standard BOGB cable.






26. 568B = White/orange - 568A = White/green - BOGB = White/blue






27. 64-bit encryption level






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






29. 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.






30. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






31. Blue - orange - green and brown.






32. 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.






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






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






35. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






36. Port based network access control (PNAC)






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






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






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






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






41. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






44. 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.






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






46. Medium dependent interface crossover






47. 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.






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






49. Regular twisted-pair cabling






50. Medium dependent interface.
