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. Medium dependent interface crossover






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






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






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






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






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






7. 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.






8. 568B = Green - 568A = Orange - BOGB = Green






9. 100 Mbps






10. 10 Mbps






11. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






13. What is the most common cable used today?






14. 568B = White/green - 568A = White/orange - BOGB = White/orange






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. The older standard BOGB cable.






17. 64-bit encryption level






18. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






21. 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






22. 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.






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






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






25. Regular twisted-pair cabling






26. 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.






27. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






29. Telecommunications Industry Association/Electronics Industries Alliance






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






31. 568B = Orange - 568A = Green - BOGB = Blue






32. 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.






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






34. 128-bit encryption level






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






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






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






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






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






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






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






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






43. Medium dependent interface.






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






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






46. 568B = Brown - 568A = Brown - BOGB = Brown






47. 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.






48. 128- -192- - and 256-bit






49. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






50. 568B = Blue - 568A = Blue - BOGB = Orange
