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.

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






3. 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.






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






5. What is used to identify a wireless network?






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

9. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






10. 64-bit encryption level






11. The older standard BOGB cable.






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






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






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






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






16. 128- -192- - and 256-bit






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






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






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






20. 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.






21. Telecommunications Industry Association/Electronics Industries Alliance






22. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






23. 568B = White/brown - 568A = White/brown - BOGB = White/brown






24. The standard BOGB cable.






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






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






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






28. 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.






29. 568B = White/green - 568A = White/orange - BOGB = White/orange






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






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






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






33. Port based network access control (PNAC)






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






35. 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.






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






38. Regular twisted-pair cabling






39. What is the most common cable used today?






40. 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?






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






42. 568B = Orange - 568A = Green - BOGB = Blue






43. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






46. 100 Mbps






47. Medium dependent interface.






48. Blue - orange - green and brown.






49. 568B = Green - 568A = Orange - BOGB = Green






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