VA-003 Explain Vault architecture Practice Question
A Vault cluster uses Integrated Storage with 5 nodes. After a network split, the cluster loses quorum and becomes sealed. The network is restored, but the cluster does not automatically recover. What should the administrator do to recover the cluster?
⚠ Common exam trap
HashiCorp often tests the misconception that unsealing or restarting nodes alone can recover a Raft-based cluster after quorum loss, when in fact the Raft layer must be explicitly recovered using a command like `vault operator raft recover`.
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
✓
Identify the node with the most recent data and use `vault operator raft recover` to create a new cluster from that node.
When a Vault cluster with Integrated Storage loses quorum due to a network split, the cluster seals itself to prevent split-brain. After the network is restored, the cluster does not automatically recover because the Raft consensus algorithm requires a majority of nodes to form a quorum. Option D is correct because `vault operator raft recover` allows an administrator to force a single node (typically the one with the most recent data) to form a new cluster, discarding the other nodes' data and re-establishing quorum.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use `vault operator raft snapshot restore` on each node to restore from a backup.
Why it's wrong here
Snapshot restore is for data recovery, not quorum loss.
- ✗
Restart all nodes simultaneously to force a new leader election.
Why it's wrong here
Restarting does not restore quorum.
- ✗
Manually unseal each node using the unseal keys.
Why it's wrong here
Unsealing doesn't fix quorum.
- ✓
Identify the node with the most recent data and use `vault operator raft recover` to create a new cluster from that node.
Why this is correct
Raft recover creates a new cluster from a single node.
