What is the 3 most used wide area network topology?

The three most commonly used wide area network (WAN) topologies are point-to-point, hub-and-spoke, and mesh. In a point-to-point topology, a direct connection is established between two locations, providing a simple and efficient link. The hub-and-spoke model connects multiple remote sites to a central hub, facilitating easier management and data flow. Mesh topology involves interconnecting multiple nodes directly, allowing for redundancy and resilience, as each node can communicate with multiple others.
