A large private sector bank is experiencing high latency in its mobile banking application during peak morning hours. The IT team discovers that the bottleneck is occurring at the database server where transaction logs are being written. The bank uses a star topology for its internal branch network and a mesh topology for its core data centers. To solve the issue, they consider implementing a Content Delivery Network (CDN) and upgrading their core switches. The bank also uses RSA encryption for its secure socket layer connections. Based on the scenario, which network topology provides the highest level of redundancy and fault tolerance for the bank's core data centers?
