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. 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.






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






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






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






5. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






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






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






9. 568B = White/orange - 568A = White/green - BOGB = White/blue






10. 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.






11. 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.






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






13. Telecommunications Industry Association/Electronics Industries Alliance






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






15. 100 Mbps






16. 568B = Orange - 568A = Green - BOGB = Blue






17. Blue - orange - green and brown.






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






19. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






21. 568B = Green - 568A = Orange - BOGB = Green






22. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






23. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






25. Regular twisted-pair cabling






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






27. Port based network access control (PNAC)






28. 568B = White/green - 568A = White/orange - BOGB = White/orange






29. Medium dependent interface.






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






31. 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.






32. Medium dependent interface crossover






33. 64-bit encryption level






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






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






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






37. The standard BOGB cable.






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






39. 10 Mbps






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






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






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






43. 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.






44. 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.






45. 128- -192- - and 256-bit






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






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






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






49. 256-bit encryption level






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