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






2. 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.






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






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






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






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






7. 568B = Orange - 568A = Green - BOGB = Blue






8. Medium dependent interface crossover






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






10. 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.






11. The older standard BOGB cable.






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






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






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






15. 128-bit encryption level






16. 568B = Blue - 568A = Blue - BOGB = Orange






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






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






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






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






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






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






23. 256-bit encryption level






24. Medium dependent interface.






25. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






27. 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?






28. 568B = Green - 568A = Orange - BOGB = Green






29. 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.






30. 10 Mbps






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






32. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






34. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






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






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






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






40. What is used to identify a wireless network?






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






42. 100 Mbps






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






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






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






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






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






48. 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.






49. 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.






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