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






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






3. 10 Mbps






4. 568B = Blue - 568A = Blue - BOGB = Orange






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






7. What is the most common cable used today?






8. 568B = White/orange - 568A = White/green - BOGB = White/blue






9. What is used to identify a wireless network?






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






11. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






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






15. 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.






16. 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.






17. The standard BOGB cable.






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






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






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






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






22. 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?






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






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






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






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






27. 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.






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






29. Medium dependent interface crossover






30. Port based network access control (PNAC)






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






32. Blue - orange - green and brown.






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






34. Regular twisted-pair cabling






35. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






37. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






38. 64-bit encryption level






39. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






42. 100 Mbps






43. 568B = Brown - 568A = Brown - BOGB = Brown






44. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






46. 568B = Green - 568A = Orange - BOGB = Green






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






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






49. 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






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