A client-to-site VPN, also known as a remote access VPN, allows individual users to connect to a private network from a remote location over the internet. The term "on-demand access" accurately describes how users can initiate a connection to the private network whenever they need to, offering flexibility and convenience. This type of VPN is particularly useful for remote workers who require access to their organization's resources without the need for a constant connection.

In contrast, a constant connection between two networks refers to a site-to-site VPN, where networks are permanently linked rather than allowing individual clients to connect on their own schedule. The option suggesting software installation alludes to some types of VPNs that may require client software, but many client-to-site VPNs can be established with minimal or no installation, depending on the setup. Finally, a direct connection between multiple sites does not pertain to client-to-site configurations but instead describes site-to-site VPNs, which link various networks together without individual client connections.
