Which design feature limits the impact of a distribution switch failure in an enterprise network?

• The installation of redundant power supplies
• The purchase of enterprise equipment that is designed for large traffic volume
• The use of a collapsed core design
• The use of the building switch block approach

Explanation: Routers or multilayer switches are usually deployed in pairs, with access layer switches evenly divided between them. This configuration is referred to as a building switch block or a departmental switch block. Each switch block acts independently of the others. As a result, the failure of a single device does not cause the network to go down. Even the failure of an entire switch block does not affect a significant number of end users.
