VA-003 Explain encryption as a service Practice Question
What is the primary purpose of the Vault transit secrets engine?
⚠ Common exam trap
HashiCorp often tests the distinction between 'encryption as a service' (transit engine) and 'secure storage of secrets' (KV engine), leading candidates to mistakenly choose Option E because they conflate encrypting data at rest with storing secrets.

Correct answer & explanation
✓
Encryption and decryption as a service
The Vault transit secrets engine is designed to provide encryption and decryption as a service, allowing applications to encrypt and decrypt data without managing cryptographic keys directly. It offloads the cryptographic operations to Vault, which securely stores and rotates the encryption keys, ensuring that plaintext data never leaves the application unencrypted. This enables centralized key management and policy-based access control for encryption operations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Encryption and decryption as a service
Why this is correct
Transit engine is designed for cryptographic operations.
- ✗
Token generation
Why it's wrong here
Token generation is a core Vault function, not specific to transit.
- ✗
Certificate management
Why it's wrong here
Certificate management is handled by PKI secrets engine.
- ✗
Dynamic database credentials
Why it's wrong here
Database credentials are provided by database secrets engine.
- ✗
Secure storage of secrets
Why it's wrong here
Secure storage is handled by KV secrets engine.
