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






2. 256-bit encryption level






3. 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.






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






5. 10 Mbps






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






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






8. 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.






9. 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






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






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






12. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






13. 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?






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






15. 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.






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






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






18. 100 Mbps






19. 568B = Brown - 568A = Brown - BOGB = Brown






20. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






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






24. Blue - orange - green and brown.






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






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






27. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






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






30. 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.






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






32. 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.






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






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






35. 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.






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






37. Medium dependent interface crossover






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






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






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






41. 128-bit encryption level






42. The older standard BOGB cable.






43. Regular twisted-pair cabling






44. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






46. 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.






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






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






49. 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.






50. Telecommunications Industry Association/Electronics Industries Alliance
