B
Correct Answer
The process of invalidating a certificate before its expiration (due to key compromise or mis-issuance) via CRL or OCSP
Explanation
CRL (Certificate Revocation List): large, infrequently updated. OCSP (Online Certificate Status Protocol): real-time but adds latency. OCSP Stapling: server pre-fetches and caches OCSP response. Let's Encrypt 90-day certs make revocation less critical.
