What kind of VPN configuration focuses on connecting a single remote user to a corporate network?

The correct answer is focused on connecting individual remote users to a corporate network. This type of VPN configuration allows a single device, typically a laptop or mobile device, to securely connect to the company's internal network over the internet. By utilizing encryption, this approach ensures that data transmitted between the remote user and the corporate network remains private and secure.

Client to site configurations are particularly advantageous in enabling remote employees to access resources, such as files and applications, as if they were on-site. They often use VPN client software installed on the user's device to initiate the connection. This is essential for businesses that allow employees to work from various locations while maintaining secure access to sensitive corporate resources.

The other types of VPN configurations, such as site to site or network to network, are typically designed to connect entire networks or multiple locations rather than individual users, which makes them unsuitable for scenarios requiring secure access for single remote users.
