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






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






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






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






5. 128- -192- - and 256-bit






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






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






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






9. Telecommunications Industry Association/Electronics Industries Alliance






10. 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.






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






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






13. 568B = Brown - 568A = Brown - BOGB = Brown






14. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






16. 568B = Orange - 568A = Green - BOGB = Blue






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






18. 568B = White/brown - 568A = White/brown - BOGB = White/brown






19. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






20. 568B = Blue - 568A = Blue - BOGB = Orange






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






22. Regular twisted-pair cabling






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






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






25. 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






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






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






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

30. 568B = White/green - 568A = White/orange - BOGB = White/orange






31. The standard BOGB cable.






32. You need to connect a twisted-pair cable to the back of a patch panel. What tool should you use?






33. 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.






34. 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.

42. 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?






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






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






45. 64-bit encryption level






46. 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.
