VA-003 Explain Vault architecture Practice Question
A security team needs to audit all interactions with Vault, including requests that are denied due to policy violations. They want to ensure that even if the audit device is full, Vault does not halt operations. Which audit device configuration should they recommend?
⚠ Common exam trap
A common mix-up: candidates assume any remote or syslog-based audit device inherently avoids blocking, but Vault's default audit device behavior is blocking unless explicitly configured otherwise, and only the file audit device supports a fallback path to prevent data loss without halting operations.
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
✓
File audit device with blocking=false and fallback path configured
The file audit device with `blocking=false` ensures that Vault does not block requests when the audit log cannot be written, preventing denial of service. The fallback path provides a secondary location to continue logging if the primary path fails, maintaining audit coverage without halting 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.
- ✗
Socket audit device with a remote log aggregator
Why it's wrong here
Socket audit device does not support fallback or non-blocking by default.
- ✗
File audit device with blocking=true and a separate backup file
Why it's wrong here
Blocking=true will halt Vault if the file write fails; should use non-blocking.
- ✓
File audit device with blocking=false and fallback path configured
Why this is correct
Non-blocking with fallback ensures audits continue even if primary fails, without halting Vault.
- ✗
Syslog audit device with local syslog server
Why it's wrong here
Syslog does not have a fallback mechanism; if syslog fails, audits may be lost.
