Subject: Networking Essentials

I'll give you a list of questions that I had :

1. You install an Ethernet card on a client computer. The network software initialized properly but the computer can not communicate with others on the network. All other computers can talk to the server. What is most likely the problem?

2. You have a Netware network. Initialization of the client computer works, but client can not talk to the server, other computers on network can. What is most likely the problem?

3. What is a characteristic of 802.3 10BaseT Thinnet?

4. What protocol provides assurance of packet delivery?

5. You want to connect two Ethernet LANs. They use NWLink and NETBEUI. You want to filter data and cut down network traffic. What device do you use? router

6. Your company has Ethernet with 750 computers which are WFW, W95, and NT Clients. You want to protect sensitive network data with minimal downtime. How?

7. What protocols are routable? 5 choices.

8. What examines network packets?

9. You have a network with MS-DOS clients and UNIX clients. Recently, an NT Server is added to the network. Now the UNIX machines can access all shared resources except those on the NT server. Why?

10. Which WAN transmission method will support 100 mbps?

11. What WAN transmission method transmits voice , data, and video?

12. Your computer is using COM1, COM2, LPT1, and VGA. The NIC is set forIRQ

3, I/O Base 300. Which one would be conflicting with the NIC?

13. What connectivity device works above the transport layer?

14. You need to run UTP Cat5 for 180 meters. what device would you use?

15. You have a 200 node LAN using TCP/IP, and you want to segment into 3 subnets. what do you use?

16. You have a 200 node Lan using TCP/IP, and NETBEUI. After you segment it into 3 subnets you still want to be able to use both protocols. What do you use?

17. What do you use to connect an Ethernet Lan to IBM mainframe?

18. You test your RG-58A/u cable and get the following readings:

cable = 0
t connector = infinity
terminator = 50 ohms

What do you need to do?

19. You have 2 new computers on the network. You set both computers up the same way:

MAC address = 0541D856912
IRQ = 5
I/O Base Address = 300

The computers cannot communicate with the network. What should you do?

20.You just installed a network adapter card in a PC on IPX (NWLink) network. The network drivers load ok, but the PC can't talk to the server. All the other PC's can talk to the server without any problem. What is the problem?

21. What type of network topology would have every node connected to every other node on the network? (Exhibit)

22. What do you call signal overflow from and adjacent wire?

23. Your network is using RG-58 /U and RG-58 /AU and is not working properly. What is wrong?

24. What can a network with Windows NT Workstations implement to share/protect files?
had 2 choices. share level or user level security or both

24. What can a network with Windows 95 clients implement to share/protect

25. What will replace standard phone lines?

26. Susan uses a modem that is 5 yrs old. The connection will not provide compression. What communication protocol is she using?

27. A server which performs processing for client computers is called?

28. You have a small 5-10 computer network. Which protocol do you use?

29. What purpose does NDIS and ODI serve?

30. one more question on NDIS and ODI. Can't remember how it was worded.

31. One question on what a UNC should have?

32. Maximum cable segment length of Thinnet?

33. Know that replacing Ethernet hubs to switches will reduce network utilization.
