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






2. 10 Mbps






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






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






5. 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.






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






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






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






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






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






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






12. 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.






13. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






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






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






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






19. 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.






20. Port based network access control (PNAC)






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






22. Telecommunications Industry Association/Electronics Industries Alliance






23. 100 Mbps






24. 568B = Brown - 568A = Brown - BOGB = Brown






25. 568B = Blue - 568A = Blue - BOGB = Orange






26. What is used to identify a wireless network?






27. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






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






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






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






33. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






35. 128-bit encryption level






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






37. Regular twisted-pair cabling






38. 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.






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






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






41. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






42. The standard BOGB cable.






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






44. 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.






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






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






47. Medium dependent interface.






48. What is the most common cable used today?






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






50. 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.
