What is an example of a Host-to-Site VPN topology?

In a Host-to-Site VPN topology, one of the primary characteristics is that it allows individual users, such as employees, to establish secure connections to a central corporate network from remote locations. This is particularly useful for remote access since it enables employees to connect to the corporate resources as if they were physically present in the office.

When considering the options, the scenario of an employee remoting into the corporate network exemplifies this concept perfectly. The connection is established from the employee's device (the "host") directly to the corporate network (the "site"), facilitating a secure interface for accessing company resources, applications, and files remotely while ensuring the confidentiality and integrity of the data transmitted.

In contrast, the other options describe different types of network connections or scenarios that do not fit the definition of a Host-to-Site VPN. For instance, a connection between two servers typically represents a server-to-server relationship rather than a user's individual connection to a network. Personal device connections may refer to peer-to-peer interactions, and linking various branch offices pertains more to a Site-to-Site VPN configuration, where entire networks connect securely rather than individual users accessing a central network.
