A user was reissued a smart card after the previous smart card had expired. The user is able to log into the
domain but is now unable to send digitally signed or encrypted email. Which of the following would the user
need to perform?

A.
Remove all previous smart card certificates from the local certificate store.

B.
Publish the new certificates to the global address list.

C.
Make the certificates available to the operating system.

D.
Recover the previous smart card certificates.

Explanation:
CAs can be either private or public, with VeriSign being one of the best known of the public variety. Many
operating system providers allow their systems to be configured as CA systems. These CA systems can be
used to generate internal certificates that are used within a business or in large external settings. The process
provides certificates to the users. Since the user in question has been re-issued a smart card, the user must
receive a new certificate by the CA to allow the user to send digitally signed email. This is achieved by
publishing the new certificates to the global address list.
