1. Blue - orange - green and brown.






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






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






4. 568B = Blue - 568A = Blue - BOGB = Orange






5. 100 Mbps






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






7. 64-bit encryption level






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






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






10. 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.






11. What is the most common cable used today?






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






13. 128-bit encryption level






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






15. 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.






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






17. 256-bit encryption level






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






19. 568B = Brown - 568A = Brown - BOGB = Brown






20. 128- -192- - and 256-bit






21. 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?






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






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






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






25. 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.






26. Medium dependent interface crossover






27. The older standard BOGB cable.






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






29. Telecommunications Industry Association/Electronics Industries Alliance






30. Multi-mode fiber (The Medium) - Half duplex: 400 meters; full duplex: 2 km - Single-mode fiber (The Medium) - Full duplex: 10km






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






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






33. 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.






34. 568B = Orange - 568A = Green - BOGB = Blue






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






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

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






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






42. 568B = Green - 568A = Orange - BOGB = Green






43. 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.






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






45. 568B = White/brown - 568A = White/brown - BOGB = White/brown






46. Medium dependent interface.






47. 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.






48. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






49. 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.
