* B: GitHub- User-focused, requires human GitHub login. Incorrect.Vault Docs Insight:"GitHub auth... typically for human users."
* C: TLS- Certificate-based, perfect for M2M. Correct.Vault Docs Insight:"TLS auth uses certificates...
suited for machine authentication."
* D: Token- Pre-generated tokens for automation. Correct.Vault Docs Insight:"Token auth... can be used by machines with proper management."
