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.

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






20. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






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

25. Telecommunications Industry Association/Electronics Industries Alliance






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






27. 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.






28. 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.






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






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






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






32. What is used to identify a wireless network?






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






34. 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.
