Which VPN topology example connects two branches of a corporate network?

The Site-to-Site VPN topology is designed specifically to connect two or more remote networks securely over the internet. This configuration is particularly valuable for organizations that have multiple branch offices needing to communicate with each other, as it creates a dedicated tunnel for secure transmission of data between those locations.

In this setup, routers or firewalls at each branch office serve as VPN endpoints, automatically establishing a secure connection whenever data needs to be transmitted. This allows for seamless communication and resource sharing across the corporate network, resembling a single unified network despite being physically distributed.

Other VPN topologies, like Host-to-Site or Client-to-Server, focus on individual users connecting to a main site or server rather than connecting entire networks. Peer-to-Peer does not pertain to corporate networks specifically; it's often associated with file sharing between individual users. Therefore, the Site-to-Site configuration is the only one that effectively meets the requirement of connecting two branches of a corporate network.
