VA-003 Explain Vault architecture Practice Question
Which of the following are valid ways to authenticate to Vault? (Select all that apply.)
⚠ Common exam trap
A common mistake is to assume that only built-in auth methods like token, LDAP, or Kubernetes are valid, while forgetting that plugin-based methods like SAML and external integrations like GitHub are also officially supported. This question tests knowledge of the breadth of supported auth methods.

Correct answer & explanation
✓
SAML 2.0
All of SAML 2.0, GitHub personal access token, Kubernetes auth, and LDAP authentication are valid Vault authentication methods. The SAML auth method (via plugin) enables integration with identity providers; the GitHub auth method uses personal access tokens to authenticate based on team membership; Kubernetes auth allows authentication using a Kubernetes Service Account Token; and LDAP authentication provides integration with LDAP directories. AWS EC2 instance metadata is not a direct Vault authentication method, though Vault's AWS auth method can use EC2 metadata for authentication.
