VA-003 Explain encryption as a service Practice Question
Which TWO are benefits of using Vault's encryption as a service?
⚠ Common exam trap
HashiCorp often tests the misconception that encryption as a service is for encrypting cloud storage at rest, when in fact it is for application-level data encryption without key management exposure.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Allows applications to delegate encryption/decryption to Vault without handling keys
Vault's encryption as a service allows applications to offload encryption and decryption operations to Vault via its API, without the application ever handling or storing encryption keys. This reduces the risk of key exposure and simplifies compliance with security policies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enables encryption of data at rest in cloud storage
Why it's wrong here
While Transit can be used for this, it's an application of the service, not a inherent benefit.
- ✓
Allows applications to delegate encryption/decryption to Vault without handling keys
Why this is correct
Core benefit of encryption as a service.
- ✓
Provides automatic key rotation and versioning
Why this is correct
Vault manages key lifecycle transparently.
- ✗
Eliminates the need for any network connectivity to Vault
Why it's wrong here
Applications must communicate with Vault over the network.
- ✗
Supports only symmetric key algorithms
Why it's wrong here
Transit supports both symmetric and asymmetric operations.
