    Q27. 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.
