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






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






3. 568B = Brown - 568A = Brown - BOGB = Brown






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






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






6. 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.






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






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






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






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






12. 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.






13. 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.






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






15. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






17. 568B = Green - 568A = Orange - BOGB = Green






18. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






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






21. 128- -192- - and 256-bit






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






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






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






25. 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?






26. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






29. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






31. What is the most common cable used today?






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






33. Medium dependent interface crossover






34. 256-bit encryption level






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






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






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






38. Telecommunications Industry Association/Electronics Industries Alliance






39. Regular twisted-pair cabling






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






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






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






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






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






45. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






47. 100 Mbps






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






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






50. 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.
