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. 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.






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






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






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






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






6. 568B = Blue - 568A = Blue - BOGB = Orange






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






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






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






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






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






12. 10 Mbps






13. Telecommunications Industry Association/Electronics Industries Alliance






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






15. 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






16. 100 Mbps






17. 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.






18. 128-bit encryption level






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






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






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






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






23. 568B = White/blue - 568A = White/blue - BOGB = White/green






24. What is used to identify a wireless network?






25. The older standard BOGB cable.






26. 568B = Brown - 568A = Brown - BOGB = Brown






27. 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.






28. 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.






29. 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?






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






31. 128- -192- - and 256-bit






32. 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.






33. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






36. Medium dependent interface crossover






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






38. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






40. 256-bit encryption level






41. 568B = White/green - 568A = White/orange - BOGB = White/orange






42. 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.






43. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






44. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






45. Blue - orange - green and brown.






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






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






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






49. 568B = Orange - 568A = Green - BOGB = Blue
