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. Blue - orange - green and brown.






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






3. 10 Mbps






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






5. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






7. 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.






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






9. 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.






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






11. Telecommunications Industry Association/Electronics Industries Alliance






12. 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?






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






14. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






16. What is used to identify a wireless network?






17. 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.






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






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






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






21. 100 Mbps






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






23. 128-bit encryption level






24. 568B = Orange - 568A = Green - BOGB = Blue






25. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






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






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






30. 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.






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






32. What is the most common cable used today?






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






34. 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.






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






36. 256-bit encryption level






37. Medium dependent interface.






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






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






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






41. 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






42. The standard BOGB cable.






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






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






45. 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.






46. 568B = White/brown - 568A = White/brown - BOGB = White/brown






47. The older standard BOGB cable.






48. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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