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. Used to extend the coverage of a wireless network.






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






3. What is the most common cable used today?






4. 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.






5. 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.






6. What is used to identify a wireless network?






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






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






9. 100 Mbps






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






11. 10 Mbps






12. The standard BOGB cable.






13. The older standard BOGB cable.






14. 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.






15. Regular twisted-pair cabling






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






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






18. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






21. Port based network access control (PNAC)






22. 256-bit encryption level






23. 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.






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






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






26. 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.






27. 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.






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






29. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






32. 568B = Brown - 568A = Brown - BOGB = Brown






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






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






35. 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.






36. Medium dependent interface.






37. 128-bit encryption level






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






39. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






40. 128- -192- - and 256-bit






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






42. Telecommunications Industry Association/Electronics Industries Alliance






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






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






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






46. Blue - orange - green and brown.






47. 64-bit encryption level






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






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






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