The benefits of a hierarchical network design over flat network designs, as implied in Network Design and Management, include:

a. Local traffic remains local in a hierarchical network design. This is because the network is divided into smaller, more manageable blocks. Only traffic destined for other networks is moved to a higher layer.

b. Hierarchical network designs clearly designate where different functions occur in the network. This can make the network easier to manage and troubleshoot.

d. A network built on a hierarchical architecture allows for both flexibility and growth, meeting the four fundamental design goals. This is because it's easier to scale and modify a hierarchical network than a flat network.

f. In networking, a hierarchical design is used to group devices into multiple networks. These networks are organized in a layered approach, which can make the network more efficient and easier to manage.

Please note that options c and e are not benefits of a hierarchical network design over flat network designs. They are rather steps in the network design process.
