Question 81 of 498
VA-003 Compare and configure secrets engines Practice Question
A company is using the PKI secrets engine to issue certificates for internal services. They want to ensure that certificates are automatically revoked if a service is decommissioned. What should they implement?
⚠ Common exam trap
It's easy for candidates to confuse passive revocation mechanisms (like CRLs or short TTLs) with active, automated revocation, assuming that expiration or client-side checks are sufficient for decommissioning scenarios.
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
✓
Use Vault's built-in lifecycle management and revocation capabilities.
Vault's PKI secrets engine includes built-in lifecycle management that can automatically revoke certificates when a lease expires or when a secret is deleted via the API. This allows you to tie certificate validity to the service's lifecycle in Vault, ensuring decommissioned services have their certificates revoked without manual intervention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Implement certificate pinning in all services.
Why it's wrong here
Pinning is a security measure, not a revocation mechanism.
- ✓
Use Vault's built-in lifecycle management and revocation capabilities.
Why this is correct
Vault can revoke certificates via API or when lease expires.
- ✗
Set a very short TTL on certificates so they expire quickly.
Why it's wrong here
Short TTL reduces risk but does not revoke; service still valid until expiration.
- ✗
Configure a Certificate Revocation List (CRL) that clients check.
Why it's wrong here
CRL is a mechanism for clients to check revocation, not automatic revocation.
