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. The standard BOGB cable.






2. 568B = Orange - 568A = Green - BOGB = Blue






3. The older standard BOGB cable.






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. 64-bit encryption level






7. What is the most common cable used today?






8. Telecommunications Industry Association/Electronics Industries Alliance






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






10. 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.






11. Provides strong authentication to devices that need to connect to the WLAN; it can also be used for regular wired LANs.






12. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






15. 568B = White/green - 568A = White/orange - BOGB = White/orange






16. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






19. 568B = Brown - 568A = Brown - BOGB = Brown






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






21. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






22. Medium dependent interface.






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






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






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






26. Regular twisted-pair cabling






27. 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.






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






29. 256-bit encryption level






30. 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.






31. 568B = White/brown - 568A = White/brown - BOGB = White/brown






32. 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.






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






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






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






36. 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?






37. 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.






38. 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.






39. Blue - orange - green and brown.






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






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






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






43. 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






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






45. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






47. 568B = White/blue - 568A = White/blue - BOGB = White/green






48. Port based network access control (PNAC)






49. 568B = White/orange - 568A = White/green - BOGB = White/blue






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