The purpose of dynamic tunnel creation between Spoke A and Spoke B is to enable communication without pre-existing tunnels. This mechanism allows satellite connections to be established on-demand, rather than requiring a static, permanent connection to exist beforehand. In scenarios such as Virtual Private Networks (VPNs), dynamic tunnels facilitate spontaneous communication between devices that may not have a predefined route or connection. When Spoke A wishes to communicate with Spoke B, a tunnel is created dynamically, allowing for efficient bandwidth usage and flexibility in network configuration. This capability is particularly advantageous in networks with numerous spokes that need to communicate intermittently, as it reduces overhead and the complexity of maintaining numerous dedicated tunnels. The other options suggest functionalities that are not primary reasons for dynamic tunnel creation. Although verification and encryption may occur when a tunnel is established, they do not directly address the necessity of establishing on-demand connections.
