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 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.






2. 568B = White/green - 568A = White/orange - BOGB = White/orange






3. 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.






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






5. What is the most common cable used today?






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






7. 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.






8. 256-bit encryption level






9. 568B = White/brown - 568A = White/brown - BOGB = White/brown






10. 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.






11. 64-bit encryption level






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






13. 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.






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






15. The standard BOGB cable.






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






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






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






19. 128- -192- - and 256-bit






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






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






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






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






24. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






26. 568B = Brown - 568A = Brown - BOGB = Brown






27. Blue - orange - green and brown.






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






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






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






31. 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






32. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






34. 568B = Blue - 568A = Blue - BOGB = Orange






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






36. 100 Mbps






37. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






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






41. 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.






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






43. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






46. Medium dependent interface crossover






47. The older standard BOGB cable.






48. For organizations - using - authentication for wireless networks is recommended.






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