12)  Situation:

You are designing a disaster prevention and recovery plan for your network. The following table

summarizes the current network configuration.
 

 Server
                    2 total - both run Microsoft Windows NT server, 1 is the
                   PDC and 1 is the BDC
 Client Computers
                   100, which run Microsoft Windows 95
 Network Type
                   10BaseT Ethernet
 

You have done the following:

. Placed all confidential data on the servers

. Placed the servers in a locked room

. Implemented NTFS user-level security on the servers to allow only specific personnel to access the data
 
 

Required result:

You must protect the servers from hardware failure. However, periods of downtime of less than 2 hours are acceptable.
You must have reasonable controls in place to protect network data from loss

Optional desired results:

You want to track all accesses to the data files.

You want to put reasonable methods in place to protect network data from virus corruption.
 

Proposed solution:

Connect UPS to each server.
Set appropriate access-control security on all shared resources.
Implement disk striping with parity for each server's hard disks.
Do daily tape backups of the data, and store the tapes in a secure off-site location.
Implement virus scanning on all client computers and servers.
 

Which results do the proposed solution produced

    A. the proposed solution produces the required results and produces both of the optional
        desired results.

    B. The proposed solution produces the required results and produces only 1 of the optional desired results.

    C. The proposed solution produces the required results but does not produce either of the optional desired results.

    D. the proposed solution does not produce the required results.
 
 

13. You install an Ethernet network adapter in a client computer. The computer's network software is initialized successfully, but the computer is not able to communicate with other computers on the network. All other client computers on the network are able to communicate. What is the most likely cause of the problem?

    A. the transceiver setting of the network adapter is incorrect.

    B. the IO port address on the network adapter is incorrect.

    C. the cable segment is not properly terminated.

    D. the packet-size setting is incorrect.

14). Your network uses NWLink IPX. Initialization of your client computer's network software appears to be successful, but your client computer is not able to access the server. All of the other computers are able to access the server. What is the most likely cause of the problem?
 

    A. the wrong network-adapter driver is installed in your client computer.

    B. your client computer has insufficient extended memory.

    C. the network adapter in your client computer is configured to use the wrong I/O port
        address.

    D. the network adapter in your client computer is configured to use the wrong frame type.

15) A client computer on your Ethernet network is not able to access the server. Initialization of the client computer's network software was successful. All other client computers are able to access the server. After investigation, you decide that hardware is not causing the problem.

What is the most likely cause of the problem?

    A. There is insufficient extended memory in the affected client computer.

    B. The network adapter in the server is configured to use the wrong transceiver.

    C. the network adapter in the affected client computer is configured to use the wrong transceiver.

    D. An excessive number of collisions is occurring on the media.
 
 

16. Situation:

Network monitoring shows that network utilization has grown from 30 percent to 70 percent of maximum capacity in the past year. You will add 24 client computers and 1 server within 3 months. You want to reduce network utilization.
 

Required result:

You must reduce network utilization by 50 percent.
 

Optional desired results:

You want to allow for continued network growth.
You want to maintain the new network utilization levels even after the planned additions to the network are implemented.
You want to minimize costs for the project.
 

Proposed solution:

Change the maximum packet size on all of the computers from 1,514 bytes to 576 bytes. Replace all Category 3 UTP cable with Category 5 UTP
cable. Increase TCP window size from 4,096 bytes to 16,384 bytes.
 

Which results does the proposed solution produce?

    A. the proposed solution produces the required result and produces all of the optional
        desired results.

    B. the proposed solution produces the required result and produces only 2 of the optional
        desired results.

    C. The proposed solution produces the required result but does not produce any of the optional desired results.

    D. the proposed solution does not produce the required result.
