    A network engineer spends time thinking about the entire Class B network 172.16.0.0, and how to subnet that network. He then chooses how to subnet this Class B network and creates an addressing and subnetting plan, on paper, showing his choices. If you compare his thoughts about this network before subnetting the network, to his thoughts about this network after mentally subnetting the network, which of the following occurred to the parts of the structure of addresses in this network?

    • The subnet part got smaller.

    • The host part got smaller

    • The network part got smaller.

    • The host part was removed.

    • The network part was removed.

    Correct Answer
    A. The host part got smaller
