In a hub-and-spoke VPN topology, who is considered the hub?

In a hub-and-spoke VPN topology, the hub is fundamentally the central point that manages and facilitates communication between all the connected spokes, which represent the individual remote sites or users. In this model, the main organization typically serves as the hub because it is where the central resources, services, and management functions are located.

The main organization, functioning as the hub, handles the routing of all traffic that flows between the various spokes. This allows for centralized control and security, ensuring that all remote connections are managed under a singular policy framework. The spokes, which can include remote offices or individual users, connect to this hub to access the organization's network resources and services, making the main organization essential in establishing and maintaining communication across the entire network.

Other choices, such as remote offices, individual users, or network service providers, do not serve the same role. Remote offices and individual users connect to the main organization but do not manage the overall traffic flow. Network service providers may facilitate the VPN connection but are not part of the topology as they do not provide the management or resource functions within the environment. Thus, the main organization is accurately described as the hub in a hub-and-spoke VPN topology.
