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






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






3. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






4. 128- -192- - and 256-bit






5. What is used to identify a wireless network?






6. What is the most common cable used today?






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






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






9. 256-bit encryption level






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






11. The standard BOGB cable.






12. Regular twisted-pair cabling






13. 568B = Blue - 568A = Blue - BOGB = Orange






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






15. 10 Mbps






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






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






18. Port based network access control (PNAC)






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






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






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






22. 568B = Brown - 568A = Brown - BOGB = Brown






23. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






24. Gigabit networks. Has different versions that run at 250 MHz and 500 MHz.






25. 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.






26. 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.






27. 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.






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






29. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






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






33. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






37. Telecommunications Industry Association/Electronics Industries Alliance






38. 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






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






40. 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.






41. Blue - orange - green and brown.






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






43. 568B = White/green - 568A = White/orange - BOGB = White/orange






44. 568B = Orange - 568A = Green - BOGB = Blue






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






46. Medium dependent interface crossover






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






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






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






50. 128-bit encryption level
