Which topology features many redundant interconnections between network nodes?

1. Star topology

2. Bus topology

3. Mesh topology

4. Ring topology

The correct answer is: Mesh topology

The topology characterized by many redundant interconnections between network nodes is the mesh topology. In a mesh network, every node is connected to multiple other nodes, creating numerous paths for data to travel. This redundancy enhances the network's reliability, as the failure of one connection does not disrupt overall communications; data can be rerouted through alternative pathways. This makes mesh topology particularly valuable in environments where high availability and fault tolerance are required, as it ensures that the network remains operational even in the event of hardware failure or link issues. The extensive interconnections allow for efficient data routing and minimize the risk of bottlenecks, unlike topologies that feature a more linear or centralized connection strategy.
