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






3. 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?






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






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






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






7. 100 Mbps






8. 568B = White/green - 568A = White/orange - BOGB = White/orange






9. 64-bit encryption level






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






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






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






13. 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.






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






15. 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.






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






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






18. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






19. 10 Mbps






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






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






22. 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.






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






24. 568B = Green - 568A = Orange - BOGB = Green






25. 568B = White/brown - 568A = White/brown - BOGB = White/brown






26. 128-bit encryption level






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






28. 256-bit encryption level






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






30. 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.






31. Telecommunications Industry Association/Electronics Industries Alliance






32. 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.






33. Blue - orange - green and brown.






34. Port based network access control (PNAC)






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






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






37. 568B = Blue - 568A = Blue - BOGB = Orange






38. Instead of using crossover cables to connect computers to central connecting devices such as switches - these central connecting devices are equipped with _______ ports - which take care of the cross.






39. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






42. 128- -192- - and 256-bit






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

45. The standard BOGB cable.






46. Regular twisted-pair cabling






47. 568B = Brown - 568A = Brown - BOGB = Brown






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






49. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






50. 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.
