Wired And Wireless Networks

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






2. 100 Mbps






3. 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.






4. 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.






5. 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.






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






7. 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.






8. What is the most common cable used today?






9. Telecommunications Industry Association/Electronics Industries Alliance






10. Regular twisted-pair cabling






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






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






13. 568B = Green - 568A = Orange - BOGB = Green






14. 568B = Blue - 568A = Blue - BOGB = Orange






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






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






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






18. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






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






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






23. 10 Mbps






24. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






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






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






28. Blue - orange - green and brown.






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






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






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






32. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






36. The older standard BOGB cable.






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






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






39. 568B = White/green - 568A = White/orange - BOGB = White/orange






40. 568B = Brown - 568A = Brown - BOGB = Brown






41. 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?






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






43. 64-bit encryption level






44. The standard BOGB cable.






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






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






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






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






49. 568B = White/blue - 568A = White/blue - BOGB = White/green






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