HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q12-Q17):

NEW QUESTION # 12
You want to integrate a third-party application to retrieve credentials from the HashiCorp Vault API. How can you accomplish this without having direct access to the source code?

A. Put in a request to the third-party application vendor
B. Use the Vault Agent to obtain secrets and provide them to the application
C. Instead of the API, have the application use the Vault CLI to retrieve credentials
D. You cannot integrate a third-party application with Vault without being able to modify the source code

Answer: B

Explanation:
Comprehensive and Detailed in Depth Explanation:
Integrating a third-party application with Vault without modifying its source code requires a solution that handles authentication and secret retrieval externally, then delivers secrets in a way the application can consume (e.g., files or environment variables). Let's break this down:
* Option A: You cannot integrate a third-party application with Vault without being able to modify the source codeThis is overly restrictive and incorrect. Vault provides tools like the Vault Agent, which can authenticate and fetch secrets on behalf of an application without requiring code changes.
The agent can render secrets into a format (e.g., a file) that the application reads naturally. This option ignores Vault's flexibility for such scenarios. Incorrect.
* Option B: Put in a request to the third-party application vendorWhile this might eventually lead to native Vault support, it's impractical, slow, and depends on the vendor's willingness and timeline. It doesn't address the immediate need to integrate without source code access. This is a passive approach, not a technical solution within Vault's capabilities. Incorrect.
* Option C: Instead of the API, have the application use the Vault CLI to retrieve credentialsThe Vault CLI is designed for human operators or scripts, not seamless application integration. Third-party applications without source code modification can't invoke the CLIprogrammatically unless they're scripted to do so, which still requires external orchestration and isn't a clean solution. This approach is clunky, error-prone, and not suited for real-time secret retrieval in production. Incorrect.
* Option D: Use the Vault Agent to obtain secrets and provide them to the applicationThe Vault Agent is a lightweight daemon that authenticates to Vault, retrieves secrets, and renders them into a consumable format (e.g., a file or environment variables) for the application. For example, if the application reads a config file, the agent can write secrets into that file using a template. This requires no changes to the application's code-just configuration of the agent and the application's environment.
It's a standard, scalable solution for such use cases. Correct.
Detailed Mechanics:
The Vault Agent operates in two modes:authentication(to obtain a token) andsecret rendering(via templates). For a third-party app, you'd configure the agent with an auth method (e.g., AppRole), a template (e.g., {{ with secret "secret/data/my-secret" }}{{ .Data.data.key }}{{ end }}), and a sink (e.g., /path/to/app
/config). The agent runs alongside the app (e.g., as a sidecar in Kubernetes or a daemon on a VM), polls Vault for updates, and refreshes secrets as needed. The app remains oblivious to Vault, reading secrets as if they were static configs. This decoupling is key to integrating unmodified applications.
Real-World Example:
Imagine a legacy app that reads an API key from /etc/app/key.txt. The Vault Agent authenticates with Vault, fetches the key from secret/data/api, and writes it to /etc/app/key.txt. The app starts, reads the file, and operates normally-no code changes required.
Overall Explanation from Vault Docs:
"Vault Agent... provides a simpler way for applications to integrate with Vault without requiring changes to application code... It renders templates containing secrets required by your application." This is ideal for third-party or legacy apps where source code access is unavailable.

NEW QUESTION # 13
An Active Directory admin created a service account for an internal application. You want to store these credentials in Vault, allowing a CI/CD pipeline to read and configure the application with them during provisioning. Vault should maintain the last 3 versions of this secret. Which Vault secrets engine should you use?

A. The Identity secrets engine
B. The KV v2 secrets engine
C. The LDAP secrets engine
D. The KV secrets engine

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
The requirement is to store static credentials (from Active Directory) in Vault with versioning (last 3 versions) for a CI/CD pipeline. The KV v2 secrets engine is designed for this: it stores arbitrary key-value pairs and supports versioning, allowing configuration of a maximum version count (e.g., vault kv metadata put -max- versions=3 kv/path). KV v1 (option A) lacks versioning. The LDAPengine (B) is for dynamic LDAP credentials, not static storage. The Identity engine (C) manages identities, not secrets. KV v2's versioning capability meets all needs, per its documentation.

NEW QUESTION # 14
Security requirements demand that no secrets appear in the shell history. Which command does not meet this requirement?

A. vault kv put secret/password value-itsasecret
B. vault kv put secret/password value=@data.txt
C. generate-password | vault kv put secret/password value
D. vault kv put secret/password value-SSECRET_VALUE

Answer: A

Explanation:
The command that does not meet the security requirement of not having secrets appear in the shell history is B: vault kv put secret/password value-itsasecret. This command would store the secret value "itsasecret" in the key/value secrets engine at the path secret/password, but it would also expose the secret value in the shell history, which could be accessed by other users or malicious actors. This is not a secure way of storing secrets in Vault.
The other commands are more secure ways of storing secrets in Vault without revealing them in the shell history. A. generate-password | vault kv put secret/password value would use a pipe to pass the output of the generate-password command, which could be a script or a tool that generates a random password, to the vault kv put command, which would store the password in the key/value secrets engine at the path secret/password.
The password would not be visible in the shell history, only the commands. C. vault kv put secret/password value=@data.txt would use the @ syntax to read the secret value from a file named data.txt, which could be encrypted or protected by file permissions, and store it in the key/value secrets engine at the path secret
/password. The file name would be visible in the shell history, but not the secret value. D. vault kv put secret
/password value-SSECRET_VALUE would use the -S syntax to read the secret value from the environment variable SECRET_VALUE, which could be set and unset in the shell session, and store it inthe key/value secrets engine at the path secret/password. The environment variable name would be visible in the shell history, but not the secret value.

NEW QUESTION # 15
A user is assigned the following policy, and they can successfully retrieve secrets using the CLI. However, the user reports receiving an error message in the UI. Why can't the user access the secret in the Vault UI?
path "kv/apps/app01" { capabilities = ["read"] }
Successful retrieval using the CLI

(Error: Permission denied in UI)

A. The user doesn't have permissions to retrieve the data from the UI, only the CLI
B. The user needs list permissions to browse the UI
C. The user doesn't know what they're doing
D. The user's token is invalid

Answer: B

Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:Irrelevant to permissions. Incorrect.
* B:UI and CLI use the same permissions. Incorrect.
* C:UI browsing requires list on parent paths; read alone isn't enough. Correct.
* D:Token works via CLI, so it's valid. Incorrect.
Overall Explanation from Vault Docs:
"To browse the UI, users need list permissions on paths leading to the secret..." Reference:https://developer.hashicorp.com/vault/docs/concepts/policies#list

NEW QUESTION # 16
Which of the following token attributes can be used to renew a token in Vault (select two)?

A. Token accessor
B. Identity policy
C. Token ID
D. TTL

Answer: A,C

Explanation:
Comprehensive and Detailed in Depth Explanation:
Token renewal extends a token's TTL. Let's evaluate:
* A: TTL- Defines expiration time, not used for renewal. Incorrect.
* B: Token ID- The token's unique identifier; can be specified to renew it (e.g., vault token renew
<token-id>). Correct.
* C: Identity policy- Relates to access control, not renewal. Incorrect.
* D: Token accessor- A unique identifier for operations like renewal without exposing the token (e.g., vault token renew -accessor <accessor>). Correct.
Overall Explanation from Vault Docs:
"Tokens can be renewed with vault token renew using either the token ID or accessor... TTL is not an attribute for renewal." Reference:https://developer.hashicorp.com/vault/docs/commands/token/renew#token-renew
