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






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






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






4. Medium dependent interface crossover






5. 10 Mbps






6. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






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






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






10. Regular twisted-pair cabling






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






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






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






14. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






15. 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.






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






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






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






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






20. 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.






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






22. 568B = White/green - 568A = White/orange - BOGB = White/orange






23. 64-bit encryption level






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






25. 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.






26. 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.






27. What is used to identify a wireless network?






28. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






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






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






33. Medium dependent interface.






34. 568B = Blue - 568A = Blue - BOGB = Orange






35. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






36. 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.






37. 568B = White/blue - 568A = White/blue - BOGB = White/green






38. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






40. 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.






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






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






43. Telecommunications Industry Association/Electronics Industries Alliance






44. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






46. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






48. 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.






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






50. The older standard BOGB cable.
