You deployed an app that transmits sensitive data and you require the app to use the VPN. In testing, you see that the app tries to connect without the VPN. How could you fix this?
(A) Educate the users to not use the app if they do not see the VPN is running.
(B) Do not allow the user to connect to public WiFi.
(C) Ask the developer to hard code a clear text token connection string in the app to use for authentication.
(D) You must configure the VPN policy to deny app access to the network if the VPN is unavailable.
