Question 17easymultiple choice
Read the full Explain Vault architecture explanation →

A company runs Vault in a single cluster with three nodes using the Raft storage backend. The nodes are behind a load balancer that distributes traffic to all nodes. The operations team notices that occasionally, write operations (e.g., writing a secret or creating a policy) fail with a '502 Bad Gateway' error, while read operations succeed. The Vault audit logs show no errors. The load balancer health checks are configured to check the /v1/sys/health endpoint with a 200 response expected. The Vault nodes are all unsealed and the cluster is healthy. Which of the following is the most likely cause of the intermittent write failures?

Frequently asked questions

What does the VA-003 exam test about Explain Vault architecture?
Explain Vault architecture questions test whether you can apply the concept in context, not just recognise a definition.
How should I use these practice questions?
Select your answer before revealing the explanation. Then read why each option is right or wrong — this active recall approach builds retention far faster than re-reading notes.
Can I practise just Explain Vault architecture questions in a focused session?
Yes — the session launcher on this page draws every question from the Explain Vault architecture domain. Use a 10-question session first to gauge your baseline, then move to 20 or 30 once the weak spots are clear.
Where can I practise other VA-003 topics?
Use the topic links above to move to related areas, or go back to the VA-003 question bank to see all topics.
Are these real exam questions or dumps?
These are original practice questions written to test the same concepts the VA-003 exam covers. They are not copied from any real exam or dump site.
