VA-003 Compare authentication methods Practice Question
A company has a Vault cluster and wants to allow applications running in Kubernetes pods to authenticate without storing static secrets. Which Vault authentication method is specifically designed for Kubernetes?
⚠ Common exam trap
HashiCorp often tests the distinction between 'designed for Kubernetes' (Kubernetes auth) and 'can be used with Kubernetes' (JWT/OIDC or AppRole), leading candidates to pick a generic method that works but is not purpose-built.

Correct answer & explanation
✓
Kubernetes
The Kubernetes auth method is specifically designed for Kubernetes workloads. It allows pods to authenticate to Vault using their Kubernetes service account token, which Vault validates against the Kubernetes API server. This eliminates the need to store static secrets in the cluster.
