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. 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






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






3. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






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






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






7. 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.






8. 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.






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






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






11. 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.






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






13. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






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






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






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






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






20. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






21. 256-bit encryption level






22. Medium dependent interface.






23. 10 Mbps






24. 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.






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






26. 568B = Green - 568A = Orange - BOGB = Green






27. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






28. What is used to identify a wireless network?






29. 568B = Brown - 568A = Brown - BOGB = Brown






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






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






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






33. 100 Mbps






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






35. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






37. Port based network access control (PNAC)






38. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






40. 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.






41. Blue - orange - green and brown.






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






43. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






45. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






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






49. 64-bit encryption level






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