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. 10 Mbps






2. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






3. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






5. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






9. The signal degrades to such a point that it cannot be interpreted by the destination host.






10. 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.






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






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






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. The standard BOGB cable.






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






17. 64-bit encryption level






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






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






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






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






22. What is used to identify a wireless network?






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






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






25. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






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






28. The older standard BOGB cable.






29. 568B = Orange - 568A = Green - BOGB = Blue






30. Medium dependent interface crossover






31. Port based network access control (PNAC)






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






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






34. 568B = Green - 568A = Orange - BOGB = Green






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






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






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






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






39. Blue - orange - green and brown.






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






41. 568B = White/brown - 568A = White/brown - BOGB = White/brown






42. What is the most common cable used today?






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






44. Medium dependent interface.






45. 128- -192- - and 256-bit






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






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






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






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






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