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






2. Telecommunications Industry Association/Electronics Industries Alliance






3. 256-bit encryption level






4. 128-bit encryption level






5. What is the most common cable used today?






6. 128- -192- - and 256-bit






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






8. A network composed of at least one WAP and at least one computer or handheld device that can connect to the WAP.






9. 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.






10. 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.






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






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






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






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






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






16. 100 Mbps






17. 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?






18. 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.






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






20. The older standard BOGB cable.






21. 568B = White/brown - 568A = White/brown - BOGB = White/brown






22. 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.






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






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






25. 64-bit encryption level






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






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






28. Medium dependent interface crossover






29. Port based network access control (PNAC)






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






31. 568B = Blue - 568A = Blue - BOGB = Orange






32. 11 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






33. Blue - orange - green and brown.






34. Medium dependent interface.






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






36. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






37. 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.






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

40. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






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






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






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






46. Regular twisted-pair cabling






47. 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.






48. What is used to identify a wireless network?






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