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. 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.






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






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






4. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






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






7. 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.






8. The older standard BOGB cable.






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






10. 568B = White/brown - 568A = White/brown - BOGB = White/brown

12. Port based network access control (PNAC)






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






14. Regular twisted-pair cabling






15. 64-bit encryption level






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






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






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






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






20. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






21. 568B = Blue - 568A = Blue - BOGB = Orange






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






23. Telecommunications Industry Association/Electronics Industries Alliance






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






25. 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.






26. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






27. If you want to connect a computer directly to another computer without using a switch - you use a _____________.






28. 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.






29. 256-bit encryption level






30. What is the most common cable used today?






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






32. 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






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






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






35. 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.






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






37. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






39. 568B = Green - 568A = Orange - BOGB = Green






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