VA-003 Explain Vault architecture Practice Question
Which TWO are core components of Vault's architecture?
⚠ Common exam trap
HashiCorp often tests the distinction between core architectural components (Seal and Storage Backend) and optional or pluggable features (audit devices, auth methods, replication), leading candidates to mistakenly select features that are critical for operation but not part of the minimal core architecture.

Correct answer & explanation
✓
Seal
The Seal is a core component of Vault's architecture because it provides the mechanism to encrypt and decrypt the master key, which is used to protect all other keys and data within Vault. When Vault is sealed, the master key is encrypted and cannot be accessed, rendering the Vault unable to decrypt its data. Unsealing requires a threshold of unseal keys to reconstruct the master key, ensuring that no single individual can access the Vault's secrets.
