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






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






3. 568B = Blue - 568A = Blue - BOGB = Orange






4. 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.






5. 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






6. 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.






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






8. 64-bit encryption level






9. 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.






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






11. 100 Mbps






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






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






14. Telecommunications Industry Association/Electronics Industries Alliance






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






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






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






18. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






20. 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.






21. 568B = White/blue - 568A = White/blue - BOGB = White/green






22. 128- -192- - and 256-bit






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






24. The standard BOGB cable.






25. 128-bit encryption level






26. Medium dependent interface crossover






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






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






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






30. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






31. 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.






32. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






33. 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.






34. The older standard BOGB cable.






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






36. 256-bit encryption level






37. 568B = Green - 568A = Orange - BOGB = Green
