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/brown - 568A = White/brown - BOGB = White/brown






2. Port based network access control (PNAC)






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






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






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






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






7. 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






8. 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.






9. Medium dependent interface crossover






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






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






12. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






14. 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?






15. 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.






16. Regular twisted-pair cabling






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






18. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






21. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






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






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






26. 256-bit encryption level






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






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






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






30. What is the most common cable used today?






31. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






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






35. 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.






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






37. Blue - orange - green and brown.






38. 100 Mbps






39. 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.






40. 568B = White/orange - 568A = White/green - BOGB = White/blue






41. 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.






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






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






44. 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.






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






46. The older standard BOGB cable.






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






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






49. Telecommunications Industry Association/Electronics Industries Alliance






50. 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.
