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






2. Telecommunications Industry Association/Electronics Industries Alliance






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






4. 568B = White/blue - 568A = White/blue - BOGB = White/green






5. 568B = White/brown - 568A = White/brown - BOGB = White/brown






6. 128- -192- - and 256-bit






7. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






8. 568B = White/green - 568A = White/orange - BOGB = White/orange






9. 256-bit encryption level






10. 100 Mbps






11. 64-bit encryption level






12. Regular twisted-pair cabling






13. Medium dependent interface.






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






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






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






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






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






19. 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.






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






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






22. 128-bit encryption level






23. 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.






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






25. 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.






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






27. When utilizing infrastructure mode - the base unit (normally a WAP) will be configured with a _____________. This then becomes the name of the wireless network - and it is broadcast over the airwaves.






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






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






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






31. 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.






32. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






33. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






36. Which of the following is not a characteristic of 802.11n?






37. 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.






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






39. Blue - orange - green and brown.






40. The standard BOGB cable.






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






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






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






44. 10 Mbps






45. What is used to identify a wireless network?






46. The older standard BOGB cable.






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






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






49. 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?






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