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






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






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






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






5. The older standard BOGB cable.






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






7. 64-bit encryption level






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






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






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






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






12. Medium dependent interface crossover






13. 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.






14. 568B = Blue - 568A = Blue - BOGB = Orange






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






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






17. 568B = Orange - 568A = Green - BOGB = Blue






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






19. The standard BOGB cable.






20. Medium dependent interface.






21. Blue - orange - green and brown.






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






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






24. 568B = White/blue - 568A = White/blue - BOGB = White/green






25. Port based network access control (PNAC)






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






27. 568B = Brown - 568A = Brown - BOGB = Brown






28. Telecommunications Industry Association/Electronics Industries Alliance






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






30. Regular twisted-pair cabling






31. 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.






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






33. 100 Mbps






34. 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?






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






36. 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.






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






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






39. 10 Mbps






40. 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.






41. What do you call it when electrical signals jump to another set of wires?






42. 128-bit encryption level






43. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency

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






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






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






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






49. 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.






50. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency
