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






2. 64-bit encryption level






3. 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






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






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






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






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






8. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






9. Telecommunications Industry Association/Electronics Industries Alliance






10. 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.






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






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






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






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






15. 10 Mbps






16. 568B = Blue - 568A = Blue - BOGB = Orange






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






18. Blue - orange - green and brown.






19. 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.






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






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






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






23. 568B = Green - 568A = Orange - BOGB = Green






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






25. Port based network access control (PNAC)






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






27. 128- -192- - and 256-bit






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






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






31. 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?






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






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






34. 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.






35. 568B = Orange - 568A = Green - BOGB = Blue






36. Regular twisted-pair cabling






37. 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.






38. 100 Mbps






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






40. 568B = White/green - 568A = White/orange - BOGB = White/orange






41. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






44. What is the most common cable used today?






45. 568B = White/blue - 568A = White/blue - BOGB = White/green






46. The standard BOGB cable.






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






48. What is used to identify a wireless network?






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






50. 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.
