Which network topology is primarily focused on alternative routing around cities and industrial areas?

The correct answer is based on the design characteristics of network topologies, particularly in relation to routing efficiency and resilience in urban environments. The ring topology is structured in a circular format where each node connects to exactly two other nodes, creating a singular pathway for signal transmission. This design inherently allows for alternative routing options. In a city or industrial setting, this can be beneficial as it can provide redundancy; if one connection fails, data can be rerouted along the ring in the opposite direction, maintaining communication.

While other topologies, such as a mesh topology, offer extensive routing possibilities due to multiple interconnections between nodes, the specific focus of the question is on a topology that reliably maintains a path and allows for effective reroutes, which is characteristic of a ring setup. Mesh topologies often entail higher complexity and are more suited for areas requiring extensive interconnectivity rather than the focused alternative routing described.

Other topologies like star, bus, and mesh may serve various roles in networking, but do not specifically emphasize the alternative routing around urban landscapes in the same direct manner as ring topology does. Star is centralized, bus is linear and does not offer alternative paths inherently, and mesh, while robust, doesn't embody the simplicity of rerouting as effectively as the structured
