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. 64-bit encryption level






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






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






4. 128- -192- - and 256-bit






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






6. 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?






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






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






10. 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.






11. 568B = Brown - 568A = Brown - BOGB = Brown






12. 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.






13. 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.






14. 100 Mbps






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






16. Blue - orange - green and brown.






17. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






19. 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.






20. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






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






24. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






25. Telecommunications Industry Association/Electronics Industries Alliance






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






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






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






29. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






30. 568B = Green - 568A = Orange - BOGB = Green






31. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






34. 256-bit encryption level






35. 128-bit encryption level






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






37. 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.






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






39. What is the most common cable used today?






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






41. 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.






42. 10 Mbps






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






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






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






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






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






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






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






50. What is used to identify a wireless network?
