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






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

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






11. 64-bit encryption level






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






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






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






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






16. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






18. 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.






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






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






21. 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.






22. Telecommunications Industry Association/Electronics Industries Alliance






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






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






25. 10 Mbps






26. 100 Mbps






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






28. Medium dependent interface crossover






29. What is used to identify a wireless network?






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






31. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






33. 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

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






39. 256-bit encryption level






40. 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.






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






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