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






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






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






5. 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.






6. 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.






7. 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.






8. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






10. 10 Mbps






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






12. 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.






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






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






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






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






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

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






20. Telecommunications Industry Association/Electronics Industries Alliance






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






22. The older standard BOGB cable.






23. 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.






24. 568B = Brown - 568A = Brown - BOGB = Brown






25. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






26. 128-bit encryption level






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






28. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






29. 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.






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






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






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






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






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






35. Medium dependent interface.






36. 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?






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






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






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

42. 568B = White/green - 568A = White/orange - BOGB = White/orange






43. Regular twisted-pair cabling






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






45. What is used to identify a wireless network?






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