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. What is the maximum speed supported by 802.11b?






2. What is used to identify a wireless network?






3. 568B = White/blue - 568A = White/blue - BOGB = White/green






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






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






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






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






8. The standard BOGB cable.






9. 568B = Orange - 568A = Green - BOGB = Blue






10. You could also use electromagnetic shielding on devices that might be emanating an electromagnetic field. This could be done on a small scale by shielding the single device - or on a larger scale by shielding an entire room - perhaps a server room. T






11. 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.






12. The older standard BOGB cable.






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






14. 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.






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






16. 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.






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






18. 128- -192- - and 256-bit






19. 54 Mbps (Data Transfer Rate) and 2.4 GHz Frequency






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






21. 568B = Green - 568A = Orange - BOGB = Green






22. 100 Mbps and Gigabit networks and is usually rated at 350 MHz - but actual speed varies depending on several different networking factors.






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






24. 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.






25. 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.






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






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






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






29. 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.






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






31. 100 Mbps






32. Blue - orange - green and brown.

34. 600 Mbps (Data Transfer Rate) and 5 GHz and/or 2.4 GHz Frequency






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






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






37. 128-bit encryption level






38. 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?






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






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






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