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






2. The standard BOGB cable.






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






4. 10 Mbps






5. 568B = White/orange - 568A = White/green - BOGB = White/blue






6. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






8. 128-bit encryption level






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






10. 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.






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






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






13. Regular twisted-pair cabling






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






15. 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.






16. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






18. 100 Mbps






19. 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?






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






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






22. 128- -192- - and 256-bit






23. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






24. Port based network access control (PNAC)






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






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






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






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






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






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






32. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






34. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






35. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






36. 64-bit encryption level






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






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






39. The older standard BOGB cable.






40. 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.






41. What is used to identify a wireless network?






42. 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.






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






44. You could also use electromagnetic shielding on devices that might be emanating an electromagnetic field. This could be done on a small scale by shielding the single device - or on a larger scale by shielding an entire room - perhaps a server room. T






45. Telecommunications Industry Association/Electronics Industries Alliance






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






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






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






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






50. 568B = Brown - 568A = Brown - BOGB = Brown
