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. 128- -192- - and 256-bit






2. Regular twisted-pair cabling






3. 256-bit encryption level






4. 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.






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






6. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






8. The standard BOGB cable.






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






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






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






12. 100 Mbps






13. 10 Mbps






14. What is used to identify a wireless network?






15. 568B = White/orange - 568A = White/green - BOGB = White/blue






16. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






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






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






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






22. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






23. What is the most common cable used today?






24. Blue - orange - green and brown.






25. 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.






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






27. 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.






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






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






30. 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.






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






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






33. Tests all of the pins of a connection one by one.






34. The older standard BOGB cable.






35. Telecommunications Industry Association/Electronics Industries Alliance






36. 568B = White/brown - 568A = White/brown - BOGB = White/brown






37. 128-bit encryption level






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






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






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






41. 568B = White/green - 568A = White/orange - BOGB = White/orange






42. 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.






43. 568B = Brown - 568A = Brown - BOGB = Brown






44. 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.






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






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






47. 568B = Orange - 568A = Green - BOGB = Blue






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






49. 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






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