VA-003 Compare authentication methods Practice Question
A DevOps team wants to authenticate a CI/CD pipeline running on a Jenkins server outside Kubernetes. The pipeline needs to obtain short-lived tokens to read secrets. Which authentication method should be used?
⚠ Common exam trap
HashiCorp often tests the distinction between authentication methods designed for humans (LDAP, GitHub) versus those for machines (AppRole), and the trap here is assuming Kubernetes auth can be used from outside the cluster because it is commonly associated with CI/CD pipelines.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AppRole auth
AppRole auth is designed for machine-to-machine authentication, allowing Jenkins (outside Kubernetes) to obtain short-lived tokens by providing a RoleID and SecretID. This method supports automated workflows without human intervention, making it ideal for CI/CD pipelines that need to read secrets from Vault.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
AppRole auth
Why this is correct
AppRole is ideal for non-human clients like CI/CD pipelines.
- ✗
LDAP auth
Why it's wrong here
LDAP is typically for human users with directory services.
- ✗
Kubernetes auth
Why it's wrong here
Kubernetes auth requires the client to be running inside a Kubernetes cluster.
