VA-003 Explain Vault architecture Practice Question
An organization has two Vault clusters in different geographic regions and wants to replicate secrets from the primary cluster to the secondary cluster for disaster recovery. Which Vault replication feature should they use?
⚠ Common exam trap
HashiCorp often tests the distinction between DR replication and Performance replication, trapping candidates who confuse the two by assuming Performance replication can also serve as a disaster recovery solution, when in fact it allows writes on both sides and is not designed for failover scenarios.

Correct answer & explanation
✓
Disaster Recovery (DR) replication
Disaster Recovery (DR) replication is the correct Vault feature for replicating secrets from a primary cluster to a secondary cluster in a different geographic region for disaster recovery. DR replication copies all data, including secrets, policies, and tokens, in a one-way direction from primary to secondary, ensuring the secondary cluster can be promoted if the primary fails. This is distinct from performance replication, which is designed for load distribution and allows writes on both sides.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cluster replication
Why it's wrong here
Cluster replication operates within a single Vault cluster across its nodes, not between separate clusters in different regions. It is tempting because the name suggests broad replication, but it is correct when replicating data across nodes of one cluster, not for cross-cluster disaster recovery.
- ✗
Active Directory replication
Why it's wrong here
Active Directory replication copies directory objects between domain controllers and has no relationship to Vault storage or secrets. It is tempting because the word replication appears in both contexts, but it would be correct only for synchronising AD domain data, not Vault clusters.
- ✓
Disaster Recovery (DR) replication
Why this is correct
Disaster Recovery replication asynchronously mirrors the primary cluster's data to a secondary cluster in a separate region, providing warm standby failover. This satisfies the stem's requirement to replicate secrets across geographic regions for disaster recovery, unlike performance replication, which scales read throughput rather than enabling regional failover.
- ✗
Performance replication
Why it's wrong here
Performance replication scales read-heavy workloads across clusters by replicating data to secondaries that serve local reads; it does not provide the active-passive failover of secrets the disaster-recovery requirement needs. It is tempting because it also replicates data between clusters, but disaster recovery replication is the correct feature when the secondary must take over as primary.
