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






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






3. Blue - orange - green and brown.






4. 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.






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






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






7. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






8. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






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






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






13. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






15. Telecommunications Industry Association/Electronics Industries Alliance






16. Regular twisted-pair cabling






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






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






19. What is the most common cable used today?






20. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






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






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






24. 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.






25. Medium dependent interface.






26. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






27. 64-bit encryption level






28. 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.






29. 10 Mbps






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. 100 Mbps






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






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






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






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






36. 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.






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






38. 568B = White/brown - 568A = White/brown - BOGB = White/brown






39. Used to connect like devices to each other - for example - a computer to another computer - or a switch to another switch.






40. 568B = Orange - 568A = Green - BOGB = Blue






41. 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.






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






43. 568B = Brown - 568A = Brown - BOGB = Brown






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






45. 128- -192- - and 256-bit






46. The older standard BOGB cable.






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






48. 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.






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






50. 568B = Blue - 568A = Blue - BOGB = Orange
