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.
An organization uses a PostgreSQL database. They configure a database secrets engine with a role that grants read-only access. However, after revoking the lease, the database user still exists. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The revocation statement is not configured in the database connection
Option D is correct because when a database secrets engine role is configured in Vault, the revocation statement (e.g., `ALTER USER "{{name}}" NOLOGIN;` or `DROP USER IF EXISTS "{{name}}";`) must be explicitly defined in the database connection's `rotation_statements` or `revocation_statements`. If no revocation statement is set, Vault will successfully create and manage the database user but will not execute any SQL to disable or drop that user when the lease is revoked, leaving the user active in PostgreSQL.
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.
✗
The database secrets engine does not support revocation
Why it's wrong here
Database engine supports revocation; if configured correctly, it removes users.
✗
The role's default_ttl is set too high
Why it's wrong here
High TTL delays revocation but does not prevent it.
✗
The lease duration is too long
Why it's wrong here
Lease duration affects when revocation occurs, not whether it succeeds.
✓
The revocation statement is not configured in the database connection
Why this is correct
If no revocation statement is set, Vault cannot delete the user on lease revocation.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume Vault automatically removes database users on lease revocation, but in reality, the revocation behavior must be explicitly defined in the connection configuration; otherwise, no cleanup occurs.
Detailed technical explanation
How to think about this question
Under the hood, Vault's database secrets engine uses a set of templated SQL statements defined in the connection configuration: `creation_statements` for user creation, `revocation_statements` for cleanup, and optionally `rotation_statements` for password rotation. If `revocation_statements` is omitted, Vault defaults to no action on revocation, meaning the database user persists indefinitely. In production, this is a common misconfiguration that leads to credential sprawl, as Vault will continue to create users but never clean them up, potentially exhausting database user limits or creating security risks.

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.
