VA-003 Assess Vault tokens Practice Question
A team needs to issue unique tokens to each of 100 microservices, each with its own policy, and ensure that revoking one token does not affect others. Which token feature should they use?
⚠ Common exam trap
Vault often tests the misconception that token accessors (Option C) provide policy isolation, but accessors are merely handles for token management and do not control policy assignment or revocation independence.
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
✓
Token roles with distinct policies
Vault token roles allow you to define distinct policies per token, ensuring each microservice gets a unique token with its own policy. When a token is revoked, only that specific token is invalidated, leaving all others unaffected. This satisfies the requirement for independent revocation without impacting other services.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Periodic tokens
Why it's wrong here
Periodic tokens are long-lived but not designed for policy isolation per microservice.
- ✗
Orphan tokens
Why it's wrong here
Orphan tokens are independent but do not help with distinct policies; all would share the same policy if created from a parent.
- ✗
Token accessors
Why it's wrong here
Accessors help with revocation but do not address policy differentiation.
- ✓
Token roles with distinct policies
Why this is correct
Token roles enable creation of tokens with specific policies, providing isolation.
