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






2. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






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






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






6. 64-bit encryption level






7. 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.






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






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






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






11. 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.






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






13. 256-bit encryption level






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






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






16. The older standard BOGB cable.






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






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






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






20. 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.






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






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






23. Port based network access control (PNAC)






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






25. 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.






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






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






28. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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. Regular twisted-pair cabling






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






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






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






34. 100 Mbps






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






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






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






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






39. 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.






40. What is used to identify a wireless network?






41. 10 Mbps






42. 128-bit encryption level






43. Medium dependent interface.






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






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






46. The standard BOGB cable.






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






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






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






50. 568B = Green - 568A = Orange - BOGB = Green
