VA-003 Explain Vault architecture Practice Question
Which THREE are requirements for a Vault High Availability (HA) cluster?
⚠ Common exam trap
HashiCorp often tests the misconception that standby nodes can serve read requests or that a load balancer is mandatory for HA, but Vault's architecture explicitly requires standby nodes to be passive and a load balancer to be optional.
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
✓
A shared storage backend accessible by all nodes.
Vault HA clusters require a shared storage backend (e.g., Consul, Integrated Storage, or Raft) that all nodes can access to maintain consistent state. Without shared storage, standby nodes cannot synchronize data or take over seamlessly if the active node fails.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Standby nodes must be able to serve read requests.
Why it's wrong here
In basic HA, standby nodes are idle; performance replicas can serve reads.
- ✗
A load balancer in front of all nodes.
Why it's wrong here
Recommended but not required; clients can be configured to talk to active node.
- ✓
A shared storage backend accessible by all nodes.
Why this is correct
All nodes must read/write to the same storage.
- ✓
The active node must be able to handle all requests.
Why this is correct
Active node processes all client requests.
- ✓
Standby nodes must forward requests to the active node.
Why this is correct
Standby nodes redirect client requests to the active node.
