HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q147-Q152):

NEW QUESTION # 147
What could you do with the feature found in the screenshot below (select two)?

A. Encrypt the Vault master key that is stored in memory
B. Using a short TTL, you could encrypt data in order to place only the encrypted data in Vault
C. Use response-wrapping to protect data
D. Encrypt sensitive data to send to a colleague over email

Answer: C,D

Explanation:
Comprehensive and Detailed in Depth Explanation:
The screenshot highlights Vault'sresponse wrappingfeature, accessible via the UI's "Wrap" option. This feature wraps a Vault response (e.g., a secret or token) in a single-use token with a configurable TTL, ensuring secure delivery to an intended recipient. Let's evaluate each option against this capability:
* Option A: Using a short TTL, you could encrypt data in order to place only the encrypted data in VaultThis misinterprets response wrapping. Wrapping doesn't encrypt data for storage in Vault; it secures a response for transmission outside Vault. Encryption for storage would involve the Transit secrets engine, not wrapping. The TTL in wrapping limits the wrapped token's validity, not the data's encryption lifecycle. This option conflates two unrelated features and is incorrect.Vault Docs Insight:
"Response wrapping does not store data in Vault; it delivers it securely to a recipient." (No direct storage implication.)
* Option B: Encrypt the Vault master key that is stored in memoryThe master key in Vault is already encrypted at rest (in storage) and decrypted in memory during operation using the unseal process (e.g., Shamir shares or auto-unseal). Response wrapping doesn't interact with the master key-it's a client- facing feature for secret delivery, not an internal encryption mechanism. This is a fundamental misunderstanding of Vault's architecture and wrapping's purpose. Incorrect.Vault Docs Insight:"The master key is managed by the seal mechanism, not client-facing features like wrapping." (See seal
/unseal docs.)
* Option C: Encrypt sensitive data to send to a colleague over emailThis aligns perfectly with response wrapping. You can retrieve a secret (e.g., vault read secret/data/my-secret), wrap it with a short TTL (e.g., 5 minutes), and receive a token (e.g., hvs.<token>). You email this token to a colleague, who unwraps it with vault unwrap <token> to access the secret. The data is encrypted within the token, secure during transit, and expires after the TTL. This is a textbook use case for wrapping.
Correct.Vault Docs Insight:"Response wrapping... can be used to securely send sensitive data to another party, such as over email, with a limited lifetime." (Directly supported use case.)
* Option D: Use response-wrapping to protect dataThis is the essence of the feature. Wrapping protects data by encapsulating it in a single-use token, accessible only via an unwrap operation. For example, vault write -wrap-ttl=60s secret/data/my-secret returns a wrapped token, protecting the secret until unwrapped. This ensures confidentiality and controlled access, making it a core benefit of the feature. Correct.Vault Docs Insight:"Vault can wrap a response in a single-use token... protecting the data until unwrapped by the recipient." (Core definition.) Detailed Mechanics:
Response wrapping works by taking a Vault API response (e.g., a secret's JSON payload) and storing it in the cubbyholesecrets engine under a newly generated single-use token. The token's TTL (e.g., 60s) limits its validity. The API call POST /v1/sys/wrapping/wrap with a payload (e.g., {"ttl": "60s", "data": {"key":
"value"}}) returns {"wrap_info": {"token": "hvs.<token>"}}. The recipient uses vault unwrap hvs.<token> (or POST /v1/sys/wrapping/unwrap) to retrieve the original data. Once unwrapped, the token is revoked, ensuring one-time use. This leverages Vault'sencryption and token system for secure data exchange.
Real-World Example:
You generate an API key in Vault: vault write secret/data/api key=abc123. In the UI, you click "Wrap" with a
5-minute TTL, getting hvs.XYZ. You email hvs.XYZ to a colleague, who runs vault unwrap hvs.XYZ within
5 minutes to get key=abc123. After unwrapping, the token is invalid, and the secret is safe from interception.
Overall Explanation from Vault Docs:
"Vault includes a feature called response wrapping. When requested, Vault can take the response it would have sent to an HTTP client and instead insert it into the cubbyhole of a single-use token, returning that token instead... This is useful for securely delivering sensitive data." The feature excels at protecting data in transit (e.g., email) and enforcing one-time access, not internal key management or storage encryption.

NEW QUESTION # 148
Your supervisor has requested that you log into Vault and update a policy for one of the development teams.
You successfully authenticated to Vault via OIDC but do not see a way to manage the Vault policies. Why are you unable to manage policies in the Vault UI?

A. The policy associated with your login does not permit access to manage policies
B. Policies cannot be managed in the UI, only the CLI and API
C. The Vault node is sealed, and therefore you cannot manage policies
D. Policies are only available on Vault Enterprise

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
In the Vault UI, the "Policies" tab is visible only if your token's policy grants access to policy management endpoints (e.g., sys/policy in Vault OSS or sys/policies/acl in Enterprise). If the tab is missing after OIDC authentication, it's because your policy lacks permissions like read and list on these paths, preventing UI navigation to policy management. For example, a minimal policy to view policies in OSS is path "sys/policy
/*" { capabilities = ["read", "list"] }. Without this, the UI hides the tab, aligning with Vault's least-privilege model.
Option A is false; policies exist in both OSS and Enterprise, with UI support in both. Option B is incorrect; a sealed Vault prevents login entirely, not just policy access. Option C is wrong; the UI does support policy management when permitted. Vault's policy docs confirm that UI visibility depends on policy permissions.

NEW QUESTION # 149
Vault is configured with the oidc auth method and you need to log in using the CLI. What command would you use to authenticate so you can make configuration changes to Vault?

A. vault login auth/oidc/users/bryan
B. vault login username=bryan
C. vault auth oidc
D. vault login -method=oidc username=bryan

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
To authenticate via the OIDC auth method using the CLI, the vault login command with the -method flag is used. The Vault documentation states:
"To authenticate using the CLI, you could use the command vault login and specify the auth methodyou wish to use by using the -method flag. For example, if you wanted to authenticate using OIDC, you could use vault login -method=oidc [options]."
-Vault Commands: login
* A: vault login -method=oidc username=bryan is correct, specifying the OIDC method and username:
"The correct command to authenticate using the oidc auth method in Vault is vault login -method=oidc username=bryan."
-Vault Auth: OIDC
* B: vault auth oidc is invalid; auth is not a login command.
* C: vault login auth/oidc/users/bryan is incorrect syntax; it mimics an API path, not a CLI command.
* D: vault login username=bryan lacks the method specification, defaulting to token auth.

Vault Commands: login
Vault Auth: OIDC

NEW QUESTION # 150
Which of the following describes the Vault's auth method component?

A. It verifies a client against an internal or external system, and generates a token with root policy
B. It dynamically generates a unique set of secrets with appropriate permissions attached
C. It is responsible for durable storage of client tokens
D. It verifies a client against an internal or external system, and generates a token with the appropriate policies attached

Answer: D

Explanation:
The Vault's auth method component is the component that performs authentication and assigns identity and policies to a client. It verifies a client against an internal or external system, and generates a token with the appropriate policies attached. The token can then be used to access the secrets and resources that are authorized by the policies. Vault supports various auth methods, such as userpass, ldap, aws, kubernetes, etc., that can integrate with different identity providers and systems. The auth method component can also handle token renewal and revocation, as well as identity grouping and aliasing.

A. Self-managed clusters require users to handle setup, maintenance, and scaling, whereas HCP Vault Dedicated is fully managed by HashiCorp and offloads most operational tasks
B. In self-managed clusters, HashiCorp is responsible for scaling, upgrades, and patching, while HCP Vault Dedicated requires the user to handle all operational overhead
C. Neither self-managed clusters nor HCP Vault Dedicated include enterprise security features such as replication or disaster recovery
D. Both self-managed clusters and HCP Vault Dedicated require manual patching and upgrades, but only self-managed clusters are hosted in the user's cloud

Answer: A

Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:Correctly contrasts self-managed (user responsibility) with HCP Vault (HashiCorp-managed).
Correct.
* B:Both support replication; false. Incorrect.
* C:HCP Vault doesn't require manual upgrades. Incorrect.
* D:Reverses responsibilities; false. Incorrect.
