Some customers have reported receiving an untrusted certificate warning when visiting the company’s website.
The administrator ensures that the certificate is not expired and that customers have trusted the original issuer
of the certificate. Which of the following could be causing the problem?
The intermediate CA certificates were not installed on the server.
The certificate is not the correct type for a virtual server.
The encryption key used in the certificate is too short.
The client’s browser is trying to negotiate SSL instead of TLS.
In a hierarchical trust model, also known as a tree, a root CA at the top provides all of the information. The
intermediate CAs are next in the hierarchy, and they trust only information provided by the root CA. The root CA
also trusts intermediate CAs that are in their level in the hierarchy and none that aren’t.
