A. B. C. D.A.
The most likely cause of the user getting untrusted host errors and being unable to connect to the corporate resources using a web-based VPN is option A, which is the certificate has expired.
A certificate is a digital document that is used to authenticate the identity of a user or a device, and to encrypt data to ensure its confidentiality. When a user connects to a web-based VPN, the VPN server presents its digital certificate to the user's web browser to prove its identity. The web browser then checks the certificate's validity, which includes checking whether the certificate has expired, before establishing a secure connection with the VPN server.
If the certificate has expired, the web browser will display an untrusted host error and prevent the user from connecting to the VPN server. This is because an expired certificate indicates that the VPN server's identity cannot be trusted and that the connection may not be secure.
Option B, which is the browser does not support SSL, is less likely to be the cause of the problem because most modern web browsers support SSL. SSL (Secure Sockets Layer) is a security protocol that encrypts data transmitted over the internet to ensure its confidentiality.
Option C, which is the user's account is locked out, is also less likely to be the cause of the problem because if the user's account is locked out, they would not be able to log in to the VPN in the first place.
Option D, which is the VPN software has reached the seat license maximum, is also less likely to be the cause of the problem because if the VPN software has reached the seat license maximum, the user would still be able to connect to the VPN, but they may experience performance issues or be unable to connect if another user has already taken their seat license.
