VA-003 Explain Vault architecture Practice Question
A large enterprise runs Vault in a high-availability cluster with integrated storage (Raft). They notice that read requests are not being evenly distributed across nodes, causing some nodes to have high load. They want to offload read operations to standby nodes. What feature should they enable to achieve this?
⚠ Common exam trap
HashiCorp often tests the misconception that a standard load balancer or adding more Raft nodes can solve read distribution issues, but the correct solution is the Vault Enterprise-specific performance standby nodes feature, which is designed exactly for this purpose.

Correct answer & explanation
✓
Enable performance standby nodes
Performance standby nodes are a Vault Enterprise feature designed to handle read requests without participating in the Raft consensus write quorum. By enabling this, read operations are offloaded to standby nodes, distributing the load evenly and reducing the burden on the active cluster nodes. This directly addresses the uneven read distribution and high load on specific nodes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable performance standby nodes
Why this is correct
Performance standby nodes can serve read requests and handle authentication, distributing the load.
- ✗
Configure a load balancer with a round-robin algorithm
Why it's wrong here
A load balancer distributes requests but without performance standbys, standby nodes will forward requests to the active node, not reduce load.
- ✗
Enable read replicas on standby nodes
Why it's wrong here
Vault does not have a read replica concept; standby nodes forward to active node for read unless performance standbys are enabled.
- ✗
Increase the number of Raft nodes to distribute reads
Why it's wrong here
More nodes do not distribute reads; only the active node serves read requests unless performance standbys are used.
