VA-003 Explain Vault architecture Practice Question
A company requires that Vault data be continuously replicated from a primary data center to a secondary data center for disaster recovery. The secondary data center must be able to become writable in the event of a primary failure. Which Vault feature should they use?
⚠ Common exam trap
HashiCorp often tests the distinction between Performance Replication and Disaster Recovery Replication, where candidates mistakenly choose Performance Replication because they confuse read scaling with disaster recovery failover capabilities.

Correct answer & explanation
✓
Disaster Recovery Replication
Disaster Recovery (DR) Replication is the correct choice because it provides asynchronous replication of Vault data (including configuration, policies, and secrets) from a primary cluster to a secondary cluster. In the event of a primary failure, the secondary cluster can be promoted to become writable, ensuring business continuity. This feature is specifically designed for disaster recovery scenarios where the secondary site must be able to take over write operations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Performance Replication
Why it's wrong here
Performance Replication is for read scaling, not disaster recovery failover.
- ✗
Consul as storage backend
Why it's wrong here
Consul provides storage and HA coordination, but not cross-cluster replication capabilities.
- ✗
Performance Standby
Why it's wrong here
Performance Standby nodes are part of a single cluster and do not replicate data across clusters.
- ✓
Disaster Recovery Replication
Why this is correct
DR replication mirrors all data and allows promotion of the secondary cluster to primary for failover.
