VA-003 Compare authentication methods Practice Question
Which authentication method in Vault uses a shared secret (Role ID) and a dynamic secret (Secret ID) to authenticate machines or applications?
⚠ Common exam trap
HashiCorp often tests the distinction between human-oriented authentication methods (like userpass or LDAP) and machine-oriented methods (like AppRole), so the trap here is assuming that any method using a 'secret' or 'password' is equivalent, when AppRole's unique two-part structure (static Role ID + dynamic Secret ID) is the key differentiator.

Correct answer & explanation
✓
AppRole
AppRole is the correct authentication method because it is specifically designed for machine-to-machine or application-to-application authentication in Vault. It uses a static Role ID (like a username) combined with a dynamically generated Secret ID (like a password) that can be created, revoked, or have a time-to-live, providing a secure and flexible way for non-human entities to obtain a Vault token.
