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. 10 Mbps






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






3. 568B = Brown - 568A = Brown - BOGB = Brown






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






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






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






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






9. 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






10. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






13. The standard BOGB cable.






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






15. Port based network access control (PNAC)






16. What is the most common cable used today?






17. 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?






18. Telecommunications Industry Association/Electronics Industries Alliance






19. 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.






20. 256-bit encryption level






21. Blue - orange - green and brown.






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






23. 128- -192- - and 256-bit






24. What is used to identify a wireless network?






25. 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.






26. Regular twisted-pair cabling






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






28. 100 Mbps






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






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






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






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






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






34. 128-bit encryption level






35. 568B = Orange - 568A = Green - BOGB = Blue






36. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






38. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






40. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






43. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






44. Occurs when there is similar interference - measured at the cable end farthest from the transmitter.






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






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






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






48. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






50. 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.
