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






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






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






4. 568B = Brown - 568A = Brown - BOGB = Brown






5. Port based network access control (PNAC)






6. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






8. 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.






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






10. 568B = Orange - 568A = Green - BOGB = Blue






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






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






13. 128- -192- - and 256-bit






14. 100 Mbps






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






16. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






17. 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.






18. 10 Mbps






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






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






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






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






23. 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






24. Blue - orange - green and brown.






25. 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.






26. 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.






27. 568B = Green - 568A = Orange - BOGB = Green






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






29. What is used to identify a wireless network?






30. 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.






31. What is the most common cable used today?






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






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






34. 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.






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






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






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






38. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






40. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






43. 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?






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






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






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






47. Medium dependent interface.






48. Medium dependent interface crossover






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






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