cert-manager, Hard (Expert), Concepts. https://k8wiz.com/uquiz/which-of-the-following-is-a-valid-way-to-revoke-a-certificate-in-cert-manager

- A. Using the 'kubectl revoke certificate' command
- B. Deleting the Certificate resource
- C. Using the cert-manager revocation API
- D. cert-manager does not support certificate revocation

**Answer:** cert-manager does not support certificate revocation

**Explanation:** cert-manager does not natively support certificate revocation. While you can delete a Certificate resource to remove it from use, this doesn't revoke the certificate with the issuing CA. Some CAs like Let's Encrypt don't support revocation through the ACME protocol used by cert-manager.
