VA-003 Compare and configure secrets engines Practice Question
This VA-003 practice question tests your understanding of compare and configure secrets engines. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A team is using Vault's KV v2 secrets engine to store API keys for multiple microservices. They have enabled versioning and need to ensure that when a secret is deleted, it can be recovered within 30 days. Additionally, they want to keep a history of all versions for compliance. The team has noticed that some secrets are being permanently removed immediately instead of moving to a deleted state. Which configuration change should they make to enforce this behavior?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Enable 'check-and-set' on the secrets path to prevent unintended overwrites
Why wrong: Check-and-set prevents concurrent overwrites but does not affect deletion retention.
B
Set the 'delete_version_after' parameter to 30 days on the KV v2 mount
This ensures that after soft-deletion, versions are kept for 30 days before permanent removal.
C
Write a custom script that calls the 'undelete' endpoint immediately after deletion
Why wrong: This would not prevent permanent deletion; it would revert deletion but not enforce a retention period.
D
Set 'max_versions' to 1 to limit the number of retained versions
Why wrong: This limits total versions but does not control how long deleted versions are kept; it may cause older versions to be removed automatically.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the 'delete_version_after' parameter to 30 days on the KV v2 mount
Option B is correct because the 'delete_version_after' parameter on a KV v2 secrets engine mount specifies the time window (in seconds or as a duration like '30d') during which a deleted version remains in a soft-deleted state and can be recovered via the 'undelete' endpoint. Setting this to 30 days ensures that when a secret is deleted, it is not permanently removed until after that period, preserving the ability to restore it and maintaining a full version history for compliance.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
HashiCorp often tests the distinction between parameters that control version retention ('max_versions' and 'delete_version_after') versus those that control write safety ('check-and-set'), and the trap here is that candidates confuse 'max_versions' (which limits total versions) with the soft-delete retention period, leading them to pick option D instead of B.
Detailed technical explanation
How to think about this question
Under the hood, KV v2 implements a versioned key-value store where each write creates a new version, and deletion marks the version as 'deleted' (soft-delete) unless the 'delete_version_after' parameter is set to 0 (the default, which causes immediate permanent deletion). The 'delete_version_after' parameter uses a duration format (e.g., '30d', '720h') and is enforced by Vault's backend during the delete operation; after the specified time, the version is automatically purged. In a real-world scenario, a team might combine 'delete_version_after' with 'max_versions' to both retain a recovery window and cap storage growth, ensuring compliance without unbounded storage.

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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

What is the correct answer to this question?
The correct answer is: Set the 'delete_version_after' parameter to 30 days on the KV v2 mount — Option B is correct because the 'delete_version_after' parameter on a KV v2 secrets engine mount specifies the time window (in seconds or as a duration like '30d') during which a deleted version remains in a soft-deleted state and can be recovered via the 'undelete' endpoint.
