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






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






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






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






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






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






7. Regular twisted-pair cabling






8. 568B = Orange - 568A = Green - BOGB = Blue






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






10. What is the most common cable used today?






11. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






12. 128- -192- - and 256-bit






13. 568B = White/orange - 568A = White/green - BOGB = White/blue






14. Port based network access control (PNAC)






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






16. 100 Mbps






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






18. Telecommunications Industry Association/Electronics Industries Alliance






19. 10 Mbps






20. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






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






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






24. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






25. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






26. Blue - orange - green and brown.






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






28. 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.






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






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






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






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






33. 568B = Brown - 568A = Brown - BOGB = Brown






34. 568B = Blue - 568A = Blue - BOGB = Orange






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






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






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






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






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






40. What is used to identify a wireless network?






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






42. Medium dependent interface.






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






44. 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






45. 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.






46. The older standard BOGB cable.






47. 64-bit encryption level






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






49. 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.






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