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. What is used to identify a wireless network?






2. Port based network access control (PNAC)






3. The older standard BOGB cable.






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






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






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






7. The standard BOGB cable.






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






9. Regular twisted-pair cabling






10. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






13. 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.






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






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






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






17. 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.






18. 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.






19. 100 Mbps






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






21. 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.






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






23. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






25. What is the most common cable used today?






26. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






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






29. Blue - orange - green and brown.






30. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






33. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






35. 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.






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






37. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






38. 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.






39. 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.






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






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






42. 568B = Orange - 568A = Green - BOGB = Blue






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






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






45. 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






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






47. 128-bit encryption level






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






49. 10 Mbps






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