VA-003 Explain Vault architecture Practice Question
This VA-003 practice question tests your understanding of explain vault architecture. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO statements about Vault replication are correct?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
DR replication replicates all data including tokens and leases.
Option B is correct because Vault DR replication is designed to replicate all data, including tokens, leases, and secrets, to a secondary cluster for disaster recovery purposes. This ensures that the secondary cluster can take over with a complete state if the primary fails, as it mirrors the entire Vault data store.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
A DR secondary can be promoted to primary only if the primary is offline.
Why it's wrong here
Promotion can happen at any time, but it disrupts replication.
✓
DR replication replicates all data including tokens and leases.
Why this is correct
DR replication is a full data copy.
Related concept
Read the scenario before looking for a memorised answer.
✓
Performance replication allows read requests to be served locally on the secondary cluster.
Why this is correct
Performance secondaries handle reads from local storage.
Related concept

✗
Performance replication replicates all secrets and auth methods.
Why it's wrong here
Only specific mount paths are replicated.
✗
Both performance and DR replication require a shared storage backend.
Why it's wrong here
Each cluster has its own storage backend.
Common exam traps
Common exam trap: answer the scenario, not the keyword
HashiCorp often tests the misconception that performance replication replicates all data (including auth methods and mount configurations), when in fact it only replicates the data within the mount paths and does not replicate auth method configurations or system data like tokens.
Detailed technical explanation
How to think about this question
Under the hood, Vault replication uses a write-ahead log (WAL) shipping mechanism where the primary streams encrypted replication tokens and data to secondaries via a gRPC-based protocol. For DR replication, the entire data store is mirrored, including internal system data like tokens and leases, while performance replication uses a filtered approach that excludes certain system paths to allow local read scaling. In a real-world scenario, if a primary cluster experiences a regional outage, the DR secondary can be promoted to primary and serve all previously issued tokens and leases without requiring users to re-authenticate.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the VA-003 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
