VA-003 Compare and configure secrets engines Practice Question
An organization needs to automatically issue X.509 certificates for internal services. Which secrets engine should they use?
⚠ Common exam trap
HashiCorp often tests the distinction between the Transit secrets engine (encryption operations) and the PKI secrets engine (certificate issuance), leading candidates to confuse 'encryption' with 'certificate generation'.

Correct answer & explanation
✓
PKI secrets engine
The PKI secrets engine is specifically designed to generate X.509 certificates for internal services. It acts as a certificate authority (CA), handling certificate signing requests (CSRs), issuing certificates with configurable lifetimes, and managing revocation via CRLs or OCSP. This directly meets the requirement for automated certificate issuance.
