VA-003 Explain encryption as a service Practice Question
Which THREE are valid operations in the Vault transit secrets engine? (Choose three.)
⚠ Common exam trap
HashiCorp often tests candidates by mixing terms from different Vault secrets engines (e.g., PKI 'issue/revoke' with transit 'encrypt/decrypt') to see if you can distinguish the specific operations each engine supports.

Correct answer & explanation
✓
rewrap
The Vault transit secrets engine provides encryption as a service, and its core operations are encrypt, decrypt, rewrap, and datakey generation. Rewrap is valid because it decrypts ciphertext and re-encrypts it with the latest key version without exposing the plaintext to the caller, maintaining security during key rotation.
