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. Port based network access control (PNAC)






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






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






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






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






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






8. What is used to identify a wireless network?






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






10. 256-bit encryption level






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






12. 568B = Orange - 568A = Green - BOGB = Blue






13. 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






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






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






16. 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.






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






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






19. Medium dependent interface crossover






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






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






22. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






25. 128-bit encryption level






26. 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.






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






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






29. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






30. 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.






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






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






33. 568B = Blue - 568A = Blue - BOGB = Orange






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






35. 100 Mbps






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






37. 568B = Brown - 568A = Brown - BOGB = Brown






38. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






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






41. The standard BOGB cable.






42. 568B = Green - 568A = Orange - BOGB = Green

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






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






47. 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.
