VA-003 Explain Vault architecture Practice Question
A developer wants to authenticate to Vault using a username and password without any external identity provider. Which authentication method should be enabled?
⚠ Common exam trap
HashiCorp often tests the distinction between authentication methods that require external dependencies versus those that are self-contained; the trap here is that candidates may confuse token authentication (which is a result, not a method) with a credential-based login, or assume LDAP is the only option for username/password authentication.

Correct answer & explanation
✓
Userpass authentication
The userpass authentication method is designed for Vault to authenticate users directly with a username and password, without relying on any external identity provider. It stores the credentials within Vault's own backend, making it the correct choice for a standalone authentication scenario where no external system like LDAP or an OIDC provider is involved.
