Your company has a custom Web application that usesa self-signed SSL certificate. The company has an
internal certification authority (CA) and uses autoenrollment.
When external users attempt to start the Web application, Internet Explorer displays an error message that
recommends closing the Web page rather than continuing to the application.
You need to ensure that Internet Explorer does not display the error message.
What should you do?

A.
Install the current certificate into the personalstore on each client computer. Add the applications URL to
the Trusted Sites zone in Internet Explorer.

B.
Install the current certificate into the computerstore on each client computer.

C.
Purchase and install a commercial certificate on the CA server. Ensure that users trust the issuing CA.

D.
Issue a root certificate from the internal CA on the external users’ computers.
