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. The older standard BOGB cable.






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






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






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






5. 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.






6. 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.






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






8. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






9. 568B = White/brown - 568A = White/brown - BOGB = White/brown






10. 100 Mbps






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






12. Medium dependent interface.






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






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






15. 256-bit encryption level






16. The standard BOGB cable.






17. 568B = Blue - 568A = Blue - BOGB = Orange






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






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






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






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






22. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






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






26. 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.






27. Telecommunications Industry Association/Electronics Industries Alliance






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






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






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






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






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






33. 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.






34. Medium dependent interface crossover






35. 568B = Brown - 568A = Brown - BOGB = Brown






36. 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.






37. 128-bit encryption level






38. 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.






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






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






41. What is used to identify a wireless network?






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






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






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






45. 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.






46. 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.






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






48. 128- -192- - and 256-bit






49. What is the most common cable used today?






50. Regular twisted-pair cabling
