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






2. 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.






3. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






5. 568B = White/blue - 568A = White/blue - BOGB = White/green






6. Medium dependent interface.






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






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






9. What is the most common cable used today?






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






11. 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.






12. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






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






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






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






18. 568B = Blue - 568A = Blue - BOGB = Orange






19. The signal degrades to such a point that it cannot be interpreted by the destination host.






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






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






22. The standard BOGB cable.






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






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






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






26. Blue - orange - green and brown.






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






28. 568B = White/brown - 568A = White/brown - BOGB = White/brown






29. 128-bit encryption level






30. 256-bit encryption level






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






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






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






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






35. What is used to identify a wireless network?






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. 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.






38. 64-bit encryption level






39. 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.






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






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






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






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






44. 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.






45. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






48. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






49. 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.
