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. 100 Mbps






2. 568B = Blue - 568A = Blue - BOGB = Orange






3. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






4. 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.






5. Medium dependent interface.






6. 256-bit encryption level






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






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






9. The standard BOGB cable.






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






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






12. What is used to identify a wireless network?






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






14. 568B = White/blue - 568A = White/blue - BOGB = White/green






15. 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.






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






17. 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.






18. Telecommunications Industry Association/Electronics Industries Alliance






19. Blue - orange - green and brown.






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






21. The older standard BOGB cable.






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






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






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






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






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






27. 128- -192- - and 256-bit






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






29. 10 Mbps






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






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






32. 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.






33. 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?






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






35. 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.






36. 568B = White/brown - 568A = White/brown - BOGB = White/brown






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






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






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






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






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






42. Regular twisted-pair cabling






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






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






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






46. 568B = Orange - 568A = Green - BOGB = Blue






47. Port based network access control (PNAC)






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






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






50. 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.
