Correct answer: point-to-point.
Why this is the answer
The correct answer is point-to-point. A point-to-point WAN topology connects two endpoints directly. This offers simplicity in design and troubleshooting, dedicated bandwidth for good performance, and high availability between the two connected sites because there are no intermediate devices to fail. While a full mesh offers high availability and redundancy, it becomes complex and expensive with many sites. A partial mesh improves on full mesh but still adds complexity. Hub-and-spoke is simple and cost-effective but creates a single point of failure at the hub and can suffer from performance bottlenecks if the hub is overloaded.
