A. Change the certificate’s public key
B. Change the certificate’s private key

D. No action necessary
Correct Answer: C
The private key for a digital certificate is very sensitive information and must be safeguarded. If a private key is compromised, the digital certificate should be immediately revoked. It is not possible to change the keys for a certificate. The certificate must be revoked and reissued.
