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






2. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






3. 568B = White/green - 568A = White/orange - BOGB = White/orange






4. 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.






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






6. The standard BOGB cable.






7. 568B = White/blue - 568A = White/blue - BOGB = White/green






8. 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.






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






10. 568B = Green - 568A = Orange - BOGB = Green






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






12. 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.






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






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






15. 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.






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






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






18. 100 Mbps






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

21. Regular twisted-pair cabling






22. 128-bit encryption level






23. 64-bit encryption level






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. 128- -192- - and 256-bit






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






27. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






29. 568B = Blue - 568A = Blue - BOGB = Orange






30. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






33. 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.






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






35. 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.






36. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






37. What is the most common cable used today?






38. Medium dependent interface crossover






39. Telecommunications Industry Association/Electronics Industries Alliance






40. 256-bit encryption level






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






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






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






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






45. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency
