HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q284-Q289):

NEW QUESTION # 284
Which of the following Vault policies will allow a Vault client to read a secret stored at secrets/applications
/app01/api_key?

A. path "secrets/applications/app01/api_key/*" { capabilities = ["update", "list", "read"] }
B. path "secrets/applications/" { capabilities = ["read"] allowed_parameters = { "certificate" = [] } }
C. path "secrets/applications/+/api_*" { capabilities = ["read"] }
D. path "secrets/*" { capabilities = ["list"] }

Answer: C

Explanation:
Comprehensive and Detailed in Depth Explanation:
This question requires identifying a policy that permits reading the secret at secrets/applications/app01
/api_key. Vault policies use paths and capabilities to control access. Let's evaluate:
* A: path "secrets/applications/" { capabilities = ["read"] allowed_parameters = { "certificate" = []
} }This policy allows reading at secrets/applications/, but not deeper paths like secrets/applications
/app01/api_key. The allowed_parameters restriction is irrelevant for reading secrets. Incorrect.
* B: path "secrets/*" { capabilities = ["list"] }The list capability allows listing secrets under secrets/, but not reading their contents. Reading requires the read capability. Incorrect.
* C: path "secrets/applications/+/api_*" { capabilities = ["read"] }The + wildcard matches one segment (e.g., app01), and api_* matches api_key. This policy grants read access to secrets/applications
/app01/api_key. Correct.
* D: path "secrets/applications/app01/api_key/*" { capabilities = ["update", "list", "read"] }This policy applies to subpaths under api_key/, not the exact path api_key. It includes read, but the path mismatch makes it incorrect for this specific secret.
Overall Explanation from Vault Docs:
"Wildcards (*, +) allow flexible path matching... read capability is required to retrieve secret data." Option C uses globbing to precisely target the required path.

NEW QUESTION # 285
You are using Vault CLI and enable the database secrets engine on the default path of database/. However, the DevOps team wants to enable another database secrets engine for testing but receives an error stating the path is already in use. How can you enable a second database secrets engine using the CLI?

A. vault secrets enable -force database
B. vault secrets enable database database2/
C. vault secrets enable database2/
D. vault secrets enable -path=database2 database

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Vault mounts secrets engines at unique paths, and only one engine can occupy a given path (e.g., database/).
To enable a second database secrets engine, you must specify a different path using the -path flag: vault secrets enable -path=database2 database mounts a new instance at database2/. The type (database) defines the engine, and -path customizes its location, avoiding conflicts.
* A: Incorrect syntax; lacks -path and misplaces database2/.
* B: -force doesn't create a new path; it overwrites an existing engine, which isn't the goal.
* D: Omits -path and engine type, making it invalid.
The secrets engine tutorial confirms -path is required for multiple instances of the same engine type.

NEW QUESTION # 286
You need to decrypt customer data to provide it to an application. When you run the decryption command, you get the output below. Why does the response not directly reveal the cleartext data?
$ vault write transit/decrypt/phone_number ciphertext="vault:v1:tgx2vsxtlQRfyLSKvem..." Key Value
--- -----
plaintext aGFzaGljb3JwIGNlcnRpZmllZDogdmF1bHQgYXNzb2NpYXRl

A. The original data must have been encrypted
B. The output is base64 encoded
C. The user does not have permission to view the cleartext data
D. The output is actually a response wrapped token that needs to be unwrapped

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
The Vault Transit secrets engine returns decrypted data inbase64-encoded format:
* B. The output is base64 encoded: "All plaintext data must be base64-encoded before being encrypted by Vault. As a result, decrypted data is always base64 encoded." Users must decode it (e.g., using base64 -d) to see cleartext.
* Incorrect Options:
* A. Permission Issue: Permissions would cause an error, not encoded output. "Not because the user lacks permission."
* C. Wrapped Token: The output is plaintext, not a token. "Not a response wrapped token."
* D. Original Encryption: Irrelevant; the issue is encoding, not encryption state.
This encoding ensures safe transmission of binary data.

NEW QUESTION # 287
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. Instead of the API, have the application use the Vault CLI to retrieve credentials
B. Use the Vault Agent to obtain secrets and provide them to the application
C. Put in a request to the third-party application vendor
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 # 288
Which of the following are benefits of using the Vault Secrets Operator (VSO)? (Select three)

A. Support for syncing from multiple secret sources
B. Bi-directional sync between Vault and Kubernetes Secrets
C. Automatic secret drift and remediation
D. Automatic secret rotation for multiple Kubernetes resource types

Answer: A,C,D

Explanation:
Comprehensive and Detailed in Depth Explanation:
The Vault Secrets Operator (VSO) enhances secrets management in Kubernetes. The HashiCorp Vault documentation lists its benefits: "The following features are supported by the Vault Secrets Operator:
* Support for syncing from multiple secret sources.
* Automatic secret drift and remediation.
* Automatic secret rotation for Deployment, ReplicaSet, StatefulSet Kubernetes resource types." The docs explain: "VSO watches for changes to its supported Custom Resource Definitions (CRDs) and synchronizes secrets from Vault to Kubernetes Secrets, ensuring consistency (A). It detects and corrects unauthorized changes (C) and rotates secrets for specified resource types (D)."Bi-directional sync (B)is not supported-sync is one-way from Vault to Kubernetes. Thus, A, C, and D are correct.
