VA-003 Compare and configure secrets engines Practice Question
An organization wants to encrypt data in transit and at rest using a centralized key management system. Which secrets engine is designed for encryption/decryption operations without storing data?
⚠ Common exam trap
HashiCorp often tests the distinction between storing data (KV) and encrypting data (Transit), where candidates mistakenly choose KV because they associate 'encryption at rest' with storage, but Transit is the correct engine for performing encryption operations without storing the data.

Correct answer & explanation
✓
Transit secrets engine
The Transit secrets engine performs encryption/decryption operations on data in transit without storing the data itself. It is designed for centralized key management, allowing applications to send plaintext for encryption or ciphertext for decryption via API calls, while the keys remain securely managed within Vault. This makes it ideal for encrypting data in transit and at rest without persisting the data.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
KV secrets engine
Why it's wrong here
KV stores secrets but does not perform encryption operations on behalf of clients.
- ✗
PKI secrets engine
Why it's wrong here
PKI issues certificates, not encryption/decryption.
- ✗
Database secrets engine
Why it's wrong here
Database engine generates dynamic DB credentials, not encryption.
- ✓
Transit secrets engine
Why this is correct
Transit provides encryption as a service and handles key management without storing data.
