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 the signal that is transmitted on one copper wire or pair of wires creates an undesired effect on another wire or pair of wires.






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






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






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






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






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






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






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






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






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






11. 568B = Green - 568A = Orange - BOGB = Green






12. 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?






13. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






16. 128- -192- - and 256-bit






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






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






19. 10 Mbps






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






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






22. Medium dependent interface.






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






24. 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.






25. 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.






26. 568B = Brown - 568A = Brown - BOGB = Brown






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






28. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






30. 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.






31. Transmits light (photons) instead of electricity - and this light is transmitted over glass or plastic.






32. The standard BOGB cable.






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






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






35. The older standard BOGB cable.






36. Multi-mode fiber (The Medium) - Half duplex: 400 meters; full duplex: 2 km - Single-mode fiber (The Medium) - Full duplex: 10km






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






38. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






40. 128-bit encryption level






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






42. 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.






43. Blue - orange - green and brown.






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






45. 64-bit encryption level






46. Port based network access control (PNAC)






47. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






48. 568B = Orange - 568A = Green - BOGB = Blue






49. 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.






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