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






2. Medium dependent interface crossover






3. 568B = White/orange - 568A = White/green - BOGB = White/blue






4. Telecommunications Industry Association/Electronics Industries Alliance






5. 568B = Orange - 568A = Green - BOGB = Blue






6. 568B = Green - 568A = Orange - BOGB = Green






7. Blue - orange - green and brown.






8. What is used to identify a wireless network?






9. 568B = Blue - 568A = Blue - BOGB = Orange






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






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






12. 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.






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






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






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






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






18. 568B = White/green - 568A = White/orange - BOGB = White/orange






19. 100 Mbps






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






21. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






22. The standard BOGB cable.






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






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






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






26. 568B = White/brown - 568A = White/brown - BOGB = White/brown






27. 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.






28. Medium dependent interface.






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






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






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






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






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






34. 128- -192- - and 256-bit






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






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






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






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






39. 10 Mbps






40. The older standard BOGB cable.






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






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. What is the maximum speed supported by 802.11b?






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






45. Port based network access control (PNAC)






46. What is the most common cable used today?






47. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






49. 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.






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