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. 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.






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






3. The older standard BOGB cable.






4. Telecommunications Industry Association/Electronics Industries Alliance






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






6. 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






7. 568B = White/blue - 568A = White/blue - BOGB = White/green






8. 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.






9. Port based network access control (PNAC)






10. Regular twisted-pair cabling






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






12. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






13. 10 Mbps






14. What is the most common cable used today?






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






16. Medium dependent interface.






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






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






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






20. 128- -192- - and 256-bit






21. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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. 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.






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






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






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






27. What is used to identify a wireless network?






28. 100 Mbps






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






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






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






32. 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.






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






34. The standard BOGB cable.






35. 256-bit encryption level






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






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






38. 64-bit encryption level






39. 568B = Orange - 568A = Green - BOGB = Blue






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






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

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






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






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






46. 568B = White/orange - 568A = White/green - BOGB = White/blue
