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. 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.






2. 128-bit encryption level






3. 256-bit encryption level






4. 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.






5. Medium dependent interface crossover






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






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






8. What is used to identify a wireless network?






9. 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

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






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






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






18. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






21. 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.






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






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






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






25. Medium dependent interface.






26. 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?






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






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






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






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