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






2. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






3. 568B = Brown - 568A = Brown - BOGB = Brown






4. What is used to identify a wireless network?






5. Port based network access control (PNAC)






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






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






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






9. The older standard BOGB cable.






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






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






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






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






14. Blue - orange - green and brown.






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






16. 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.






17. 10 Mbps






18. 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.






19. 568B = Blue - 568A = Blue - BOGB = Orange






20. Regular twisted-pair cabling






21. Medium dependent interface.






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






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






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






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






26. 256-bit encryption level






27. 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?






28. 64-bit encryption level






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






30. 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.






31. Medium dependent interface crossover






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






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






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






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






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






37. 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.






38. 568B = White/green - 568A = White/orange - BOGB = White/orange






39. 568B = White/brown - 568A = White/brown - BOGB = White/brown






40. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






42. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






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






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






46. 100 Mbps






47. 128-bit encryption level






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






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






50. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency
