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. Medium dependent interface.






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






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






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






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






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






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






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






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






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






11. Regular twisted-pair cabling






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






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






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






15. 568B = Brown - 568A = Brown - BOGB = Brown






16. The older standard BOGB cable.






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






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






19. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






22. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






23. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






25. 568B = White/green - 568A = White/orange - BOGB = White/orange






26. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






29. 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.






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






31. 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.






32. 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.






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






34. 10 Mbps






35. 128- -192- - and 256-bit






36. The standard BOGB cable.






37. 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






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






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






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






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






42. 256-bit encryption level






43. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






44. 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.






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






46. 128-bit encryption level






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






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






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






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