VA-003 Manage Vault leases Practice Question
A Vault administrator is troubleshooting a batch of revoked database credentials. An application reported that its lease stopped working even though the application had been renewing it every few minutes. Reviewing the mount configuration, the administrator sees default_lease_ttl set to 15m and max_lease_ttl set to 2h. The application log shows successful renewals until roughly the two-hour mark, after which the renew call returned an error and the credential failed. What is the most likely explanation?
⚠ Common exam trap
The trap here is attributing a renewal failure at a fixed interval to token expiry or renewal limits instead of the lease's cumulative maximum TTL.

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
✓
The lease reached the mount's max_lease_ttl, so renewal could no longer extend it and the credential had to be reissued.
The mount's max_lease_ttl defines the absolute cumulative lifetime of a lease, and renewal cannot push a lease past that boundary. The application's renewals succeeded until the lease reached two hours, at which point renewal failed and the credential expired. The correct remediation is for the application to request a new credential when renewal is no longer granted.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The database engine rotated its root credentials, which invalidated every outstanding dynamic credential at once.
Why it's wrong here
Root credential rotation affects Vault's ability to create new users but does not instantly revoke all existing dynamic credentials at a synchronized two-hour mark. The failure timing aligns precisely with the configured maximum lease TTL, which is a deterministic per-lease boundary. Root rotation would not produce a clean cutoff exactly at the lease ceiling.
- ✗
The application's token expired, causing all leases it created to be revoked automatically at the same time.
Why it's wrong here
Token expiry revokes leases created by that token, but the symptom here is a renew failure at a time matching the mount's max_lease_ttl, not the token's own TTL. A token-expiry explanation would require the token TTL to coincidentally equal two hours and would also invalidate the app's ability to authenticate. The timing strongly implicates the lease ceiling instead.
- ✓
The lease reached the mount's max_lease_ttl, so renewal could no longer extend it and the credential had to be reissued.
Why this is correct
Renewal extends a lease only up to the cumulative maximum defined by the mount's max_lease_ttl. Once a lease has lived for two hours, further renewal attempts fail and the credential expires, regardless of how frequently the client renewed. The application must request a new credential rather than continuing to renew the exhausted lease.
- ✗
The application exceeded its allowed renewal count, and Vault rejected the renewal after a fixed number of attempts.
Why it's wrong here
Vault does not impose a fixed renewal-count limit on leases. Renewal eligibility is governed by time-based ceilings such as max_lease_ttl, not by how many times a client has renewed. A renewal-count explanation would not explain why the cutoff occurred at the two-hour mark matching the mount configuration.
