An administrator needs to renew a certificate for a web server. Which of the following should be submitted to a
CA?
A.
CSR
B.
Recovery agent
C.

Explanation:
In public key infrastructure (PKI) systems, a certificate signing request (also CSR or certification request) is a
message sent from an applicant to a certificate authority in order to apply for a digital identity certificate.
When you renew a certificate you send a CSR to the CA to get the certificate resigned.
