Which of the following is used to validate a certificate when it is presented to a user?
Online Certificate Status Protocol (OCSP) is used to validate a certificate when it is presented to a user. It allows the real-time check of the certificate's status, verifying whether it is still valid or has been revoked. This mechanism ensures immediate validation, which is crucial for secure communications and transactions.
CA issues and manages certificates. OSCP - Online Certificate Status Protocol, a protocol that checks a certificate for validity and if its been revoked (by the CA). The answer is OSCP. CA is like Congress, OSCP is like police. Congress records laws and writes them but don't actually enforce anything. Police enforce them
the question is tricky. It is basically asking what is "used" to validate a certificate when it is presented to a user.

This is how I read the question.
Certificate Authority
OCSP is used to validate the status of a digital certificate in real-time. When a certificate is presented to a user, the OCSP responder can be queried to check if the certificate is still valid or if it has been revoked. This provides a more efficient and timely method of certificate validation compared to traditional CRL (Certificate Revocation List) checks.
