This VA-003 practice question tests your understanding of utilize vault cli and api. 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 wants to retrieve a dynamic database credential from Vault. Which CLI command should be used?
vault list database/creds/readonly
Why wrong: C lists available roles, but does not generate credentials.
vault generate database/creds/readonly
Why wrong: D is not a valid vault command.
vault write database/creds/readonly
A is correct: write to the creds path generates new dynamic credentials.
vault read database/creds/readonly
Why wrong: B is used for static secrets, not dynamic generation.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
vault write database/creds/readonly
Option C is correct because Vault uses the `vault write` command to generate dynamic credentials from a database secrets engine. The `database/creds/readonly` path triggers the generation of a new credential (username/password) for the configured role, and the response includes the lease ID, username, and password. Unlike static secrets, dynamic credentials are created on demand and require a write operation to the role path.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.

C lists available roles, but does not generate credentials.
vault generate database/creds/readonly
Why it's wrong here
D is not a valid vault command.
vault write database/creds/readonly
Why this is correct
A is correct: write to the creds path generates new dynamic credentials.

B is used for static secrets, not dynamic generation.
Common exam traps
HashiCorp often tests the misconception that `vault read` is used for all secret retrieval, but dynamic secrets require a `vault write` because the operation creates a new credential rather than reading an existing one.
Trap categories for this question
Command / output trap
D is not a valid vault command.
Detailed technical explanation
Under the hood, the database secrets engine implements a `write` endpoint at `database/creds/:role_name` that creates a new database user with a temporary password, binds it to the role's configured TTL, and returns a lease. The lease ID is critical for renewal or revocation; without it, the credential cannot be managed. In real-world scenarios, teams often script `vault write` in CI/CD pipelines to fetch short-lived credentials, ensuring that if a credential is leaked, it expires automatically within minutes.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
