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. 100 Mbps






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






3. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






5. 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.






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






7. 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?






8. 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.






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






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. Used to extend the coverage of a wireless network.






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






13. Medium dependent interface.






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

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






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






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






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






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






21. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






26. 568B = White/orange - 568A = White/green - BOGB = White/blue

30. 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.






31. 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
