VA-003 Explain Vault architecture Practice Question
What is the purpose of the Seal/Unseal process in Vault architecture?
⚠ Common exam trap
HashiCorp often tests the misconception that Seal/Unseal is about key rotation or backup, when in reality it is a startup security gate that prevents Vault from processing requests until the master key is decrypted in memory.

Correct answer & explanation
✓
To enable Vault to process requests
The Seal/Unseal process in Vault is a security mechanism that protects the encryption key used to encrypt data at rest. When Vault starts, it is in a sealed state and cannot process any requests until it is unsealed by providing a threshold number of unseal keys (shards). Unsealing decrypts the master key in memory, allowing Vault to access the storage backend and serve API requests. Option D is correct because the primary purpose is to enable Vault to process requests after a secure startup.
