Wired And Wireless Networks

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. 100 Mbps






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






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






4. 128-bit encryption level






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






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






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






8. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






10. 568B = Brown - 568A = Brown - BOGB = Brown






11. Blue - orange - green and brown.






12. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






16. 256-bit encryption level






17. 568B = Orange - 568A = Green - BOGB = Blue






18. 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






19. Telecommunications Industry Association/Electronics Industries Alliance






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






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






22. 64-bit encryption level






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






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






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






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






27. What is the most common cable used today?






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






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






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






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






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






33. What is used to identify a wireless network?






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






35. 568B = Green - 568A = Orange - BOGB = Green






36. Medium dependent interface crossover






37. Regular twisted-pair cabling






38. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






39. The standard BOGB cable.






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






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






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






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






44. 128- -192- - and 256-bit






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






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






47. The older standard BOGB cable.






48. 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.






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






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