HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q236-Q241):

NEW QUESTION # 236
Which of the following token attributes can be used to renew a token in Vault (select two)?

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

Answer: B,D

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


NEW QUESTION # 237
When unsealing Vault, each Shamir unseal key should be entered:

  • A. At the command line in one single command
  • B. By different administrators each connecting from different computers
  • C. Sequentially from one system that all of the administrators are in front of
  • D. While encrypted with each administrators PGP key

Answer: B

Explanation:
When unsealing Vault, each Shamir unseal key should be entered by different administrators each connecting from different computers. This is because the Shamir unseal keys are split into shares that are distributed to trusted operators, and no single operator should have access to more than one share. This way, the unseal process requires the cooperation of a quorum of key holders, and enhances the security and availability of Vault. The unseal keys can be entered via multiple mechanisms from multiple client machines, and the process is stateful. The order of the keys does not matter, as long as the threshold number of keys is reached.
The unseal keys should not be entered at the command line in one single command, as this would expose them to the history and compromise the security. The unseal keys should not be encrypted with each administrator's PGP key, as this would prevent Vault from decrypting them and reconstructing the master key.

NEW QUESTION # 238
To protect the sensitive data stored in Vault, what key is used to encrypt the data before it is written to the storage backend?

  • A. Unseal key
  • B. Recovery key
  • C. Root key
  • D. Encryption key

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Vault encrypts all data before writing it to the storage backend using an encryption key within its cryptographic barrier. This key, stored in a keyring, is itself encrypted by the master key (split into unseal keys). The recovery key (A) is for emergency recovery, not data encryption. Unseal keys (C) unlock the master key, not encrypt data directly. The root key (D) isn't a term used in Vault's encryption flow; the master key is the closest analog, but it protects the encryption key, not the data itself. The architecture docs clarify the encryption key's role.

NEW QUESTION # 239
What could you do with the feature found in the screenshot below (select two)?

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

Answer: A,B

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 # 240
True or False? To encrypt existing encrypted data with the latest version of the encryption key, you need to first decrypt it and then request Vault to re-encrypt it with the latest version of the encryption key.

  • A. False
  • B. True

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
This statement isfalsedue to Vault's rewrap feature:
* B. False: "You can use the rewrap feature of the transit secrets engine to rewrap the data with the latest version of the key. This process does not reveal the plaintext data." Rewrapping updates the encryption key version without decryption.
* Incorrect Option:
* A. True: Incorrect; rewrapping avoids the decrypt-re-encrypt cycle.
This enhances security and efficiency in key rotation.
