- Use of a hierarchical design allows replacement of redundant devices with high-capacity network equipment.
- The hierarchical model allows the use of high-performance switches at all design layers, thus allowing for a fully-meshed topology.
- Hierarchically designed networks can more easily be expanded to suit future needs.
- Hierarchical design models enhance existing bandwidth through the use of link aggregation.
- A hierarchical design uses firewalls instead of complicated port-based and distribution layer security policies.
- The hierarchical model allows for specialized functionality at each layer, simplifying device management.
Explanation: Hierarchical design provides fault containment by constraining the network changes to a subset of the network, which affects fewer systems and makes it easy to manage as well as improve resiliency. In a modular layer design, network components can be placed or taken out of service with little or no impact to the rest of the network and this facilitates troubleshooting, problem isolation, and network management.
