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 standard BOGB cable.






2. 128- -192- - and 256-bit






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






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






5. Regular twisted-pair cabling






6. 568B = White/green - 568A = White/orange - BOGB = White/orange






7. Port based network access control (PNAC)






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






9. 10 Mbps






10. 568B = White/orange - 568A = White/green - BOGB = White/blue






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






12. 568B = White/brown - 568A = White/brown - BOGB = White/brown






13. The older standard BOGB cable.






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






15. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency






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






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






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






19. 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.






20. What is the most common cable used today?






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






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






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






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






25. 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.






26. 128-bit encryption level






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






28. Medium dependent interface crossover






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

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






32. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






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






35. 64-bit encryption level






36. 568B = Brown - 568A = Brown - BOGB = Brown

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






39. 256-bit encryption level






40. 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.






41. 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.






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






43. Medium dependent interface.






44. 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.
