VA-003 Compare authentication methods Practice Question
Which TWO authentication methods allow a machine to authenticate without storing a static secret? (Choose two.)
⚠ Common exam trap
HashiCorp often tests the misconception that AppRole is a 'secretless' method, but in reality, the RoleID is a static secret that must be stored, and the SecretID, while dynamic, still requires secure distribution, making it not truly stateless.

Correct answer & explanation
✓
Kubernetes
Kubernetes authentication in Vault uses the Kubernetes service account token (a JWT) to authenticate. The JWT is dynamically generated by the Kubernetes API server and is not a static secret stored by the machine; Vault verifies it against the Kubernetes API server's token review endpoint. This allows the machine to authenticate without storing a long-lived static credential.
