25 Questions

1. 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.

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

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

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

5. 568B = White/green - 568A = White/orange - BOGB = White/orange

6. What is the most common cable used today?

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

8. 568B = Blue - 568A = Blue - BOGB = Orange

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

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

11. 568B = White/brown - 568A = White/brown - BOGB = White/brown

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

13. 568B = Brown - 568A = Brown - BOGB = Brown

14. 128-bit encryption level

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

16. 54 Mbps (Data Transfer Rate) and 5 GHz Frequency

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

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

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

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

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. Port based network access control (PNAC)

24. 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

25. 10 Mbps
