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






2. 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.






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






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






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






6. 568B = White/orange - 568A = White/green - BOGB = White/blue






7. Port based network access control (PNAC)






8. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






10. 100 Mbps






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






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






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






14. Blue - orange - green and brown.






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






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






17. Medium dependent interface crossover






18. Medium dependent interface.






19. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






21. 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.






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






23. 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






24. 128-bit encryption level






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






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






27. 128- -192- - and 256-bit






28. The standard BOGB cable.






29. You are setting up a network within a warehouse using Category 6 UTP. however - parts of the network are down because of the heavy machinery used. What cable type should you use?






30. 64-bit encryption level






31. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






34. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






37. 568B = White/brown - 568A = White/brown - BOGB = White/brown






38. 568B = Orange - 568A = Green - BOGB = Blue






39. 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.






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






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






42. 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.






43. 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.






44. Regular twisted-pair cabling






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






46. What is the most common cable used today?






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






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






49. 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.






50. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency
