VA-003 Explain Vault architecture Practice Question
Exhibit
Refer to the exhibit. ``` $ vault status Key Value --- ----- Seal Type shamir Initialized true Sealed true Total Shares 5 Threshold 3 Version 1.13.0 Storage Type raft Cluster Name vault-cluster-abc123 Cluster ID abc123-def456-ghi789 HA Enabled true HA Cluster https://vault-1:8201 HA Mode standby Active Node Address https://vault-2:8201 ```
A Vault operator runs `vault status` and sees the output above. The Vault cluster is in production and currently unresponsive to API requests. What is the most likely cause of the unresponsiveness?
⚠ Common exam trap
HashiCorp often tests the distinction between initialization and sealing, where candidates mistakenly think an uninitialized cluster is the same as a sealed one, but initialization only happens once and sealing is a separate, reversible state that blocks all API requests.
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
✓
The Vault cluster is sealed.
The `vault status` output shows that the Vault cluster is sealed. When a Vault cluster is sealed, it cannot process any API requests because the encryption key required to decrypt the data is not available in memory. This is the most common cause of unresponsiveness in a production Vault cluster that has been properly initialized.
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 cluster is not initialized.
Why it's wrong here
Initialized is true, so initialization is not the issue.
- ✗
The cluster does not have HA enabled.
Why it's wrong here
HA Enabled is true, so HA is enabled.
- ✓
The Vault cluster is sealed.
Why this is correct
Sealed is true, meaning Vault cannot process requests until unsealed.
- ✗
The cluster has no active leader.
Why it's wrong here
Active Node Address shows vault-2, indicating an active leader exists.
