Perform User Account Management Phase 1 Practice Test

PKI stands for Public Key Infrastructure, a framework that uses public-key cryptography to issue, manage, and revoke digital certificates that bind public keys to identities. This system enables trusted communications by letting others verify who you are, encrypt data for you, and ensure message integrity. At its core, a certificate ties a public key to a real-world identity, and it’s issued by a trusted Certification Authority. Supporting pieces like a Registration Authority helps verify identities, and mechanisms such as Certificate Revocation Lists or OCSP handle revocation when a certificate should no longer be trusted. The other phrases aren’t standard terms for this concept, so they don’t describe the established framework for managing keys and trust. Public Key Infrastructure.
