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






2. The standard BOGB cable.






3. 64-bit encryption level






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






5. 568B = Brown - 568A = Brown - BOGB = Brown






6. 10 Mbps






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






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






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






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






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






12. 256-bit encryption level






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






14. 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.






15. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






18. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






20. Port based network access control (PNAC)






21. What is used to identify a wireless network?






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






23. 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.






24. 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?






25. Telecommunications Industry Association/Electronics Industries Alliance






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






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






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






29. What is the most common cable used today?






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






31. 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.






32. 568B = White/orange - 568A = White/green - BOGB = White/blue






33. 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.






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.






35. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






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






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






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






41. 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






42. Regular twisted-pair cabling






43. 128- -192- - and 256-bit






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






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






46. The older standard BOGB cable.






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






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






49. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






50. 568B = Green - 568A = Orange - BOGB = Green
