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






2. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






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






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






7. What is the most common cable used today?






8. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






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






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






13. 64-bit encryption level






14. 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.






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






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






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






18. 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.






19. 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






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






21. 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.






22. 568B = Blue - 568A = Blue - BOGB = Orange






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






24. 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.






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






26. 100 Mbps






27. 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.






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






29. 568B = White/blue - 568A = White/blue - BOGB = White/green






30. Instead of using crossover cables to connect computers to central connecting devices such as switches - these central connecting devices are equipped with _______ ports - which take care of the cross.






31. Medium dependent interface crossover






32. 128- -192- - and 256-bit






33. 256-bit encryption level






34. The older standard BOGB cable.






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






36. What is used to identify a wireless network?






37. Medium dependent interface.






38. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






40. 568B = Orange - 568A = Green - BOGB = Blue






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






42. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






43. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






44. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






45. 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.






46. The standard BOGB cable.






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






48. Regular twisted-pair cabling






49. 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?






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