The VIA web authentication profile is used to authenticate the users who want to download the VIA connection settings from the VPNCs. The VPNCs can use either an internal database or an external server (such as RADIUS or LDAP) as the authentication source for this profile. To ensure that only authorized users obtain VIA connection settings, you should use CPPM as the external server and configure a service on CPPM that uses AD as the authentication source. This way, you can leverage the role mapping and enforcement features of CPPM to check if the users belong to the “RemoteEmployees” AD group and grant or deny them access accordingly1

The other options are not correct because they do not allow you to verify the users’ AD group membership before providing them with VIA connection settings. Option B would only check the users’ credentials against AD, but not their group membership. Option C would only apply to the VPN connection phase, not the VIA connection settings phase. Option D would not work because the VPNCs do not support LDAP as an authentication source for VIA connection profiles2
