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. Regular twisted-pair cabling






2. The standard BOGB cable.






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






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






5. 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.






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






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






8. 568B = White/orange - 568A = White/green - BOGB = White/blue






9. Blue - orange - green and brown.






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






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






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






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






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






15. 568B = White/brown - 568A = White/brown - BOGB = White/brown






16. 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.






17. 128-bit encryption level






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






19. 256-bit encryption level






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






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






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






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






24. 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.






25. The older standard BOGB cable.






26. 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.






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






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






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






30. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






32. 128- -192- - and 256-bit






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






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






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






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






37. Telecommunications Industry Association/Electronics Industries Alliance






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. What is the maximum speed supported by 802.11b?






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






41. Port based network access control (PNAC)






42. What is used to identify a wireless network?






43. What is the most common cable used today?






44. Medium dependent interface crossover






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






46. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






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






49. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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