A certificate used on an e-commerce web server is about to expire.
Which of the following will occur if the certificate is allowed to expire?

A.
The certificate will be added to the Certificate Revocation List (CRL).

B.
Clients will be notified that the certificate is invalid.

C.
The e-commerce site will not function until the certificate is renewed.

D.
The e-commerce site will no longer use encryption.

Explanation:
A similar process to certificate revocation will occur when a certificate is allowed to expire. Notification will be
sent out to clients of the invalid certificate. The process of revoking a certificate begins when the CA is notified
that a particular certificate needs to be revoked. This must be done whenever the private key becomes known.
The owner of a certificate can request that it be revoked at any time, or the administrator can make the request.
