HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q141-Q146):NEW QUESTION # 141
True or False? When using the Transit secrets engine, setting the min_decryption_version will determine the minimum key length of the data key (i.e., 2048, 4096, etc.).
  • A. True
  • B. False
Answer: B
Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:Incorrect. min_decryption_version sets the minimum key version, not length.
* B:Correct. It controls versioning, not key size.
Overall Explanation from Vault Docs:
"min_decryption_version specifies the minimum key version for decryption... Key length is a separate configuration." Reference:https://developer.hashicorp.com/vault/docs/secrets/transit#usage

NEW QUESTION # 142
A web application uses Vault's transit secrets engine to encrypt data in-transit. If an attacker intercepts the data in transit which of the following statements are true? Choose two correct answers.
  • A. Even if the attacker was able to access the raw data, they would only have encrypted bits (TLS in transit)
  • B. You can rotate the encryption key so that the attacker won't be able to decrypt the data
  • C. The keys can be rotated and min_decryption_version moved forward to ensure this data cannot be decrypted
  • D. The Vault administrator would need to seal the Vault server immediately
Answer: A,C
Explanation:
A web application that uses Vault's transit secrets engine to encrypt data in-transit can benefit from the following security features:
* Even if the attacker was able to access the raw data, they would only have encrypted bits (TLS in transit). This means that the attacker would need to obtain the encryption key from Vault in order to decrypt the data, which is protected by Vault's authentication and authorization mechanisms. The transit secrets engine does not store the data sent to it, so the attacker cannot access the data from Vault either.
* The keys can be rotated and min_decryption_version moved forward to ensure this data cannot be decrypted. This means that the web application can periodically change the encryption key used to encrypt the data, and set a minimum decryption version for the key, which prevents older versions of the key from being used to decrypt the data. This way, even if the attacker somehow obtained an old version of the key, they would not be able to decrypt the data that was encrypted with a newer version of the key.
The other statements are not true, because:
* You cannot rotate the encryption key so that the attacker won't be able to decrypt the data. Rotating the key alone does not prevent the attacker from decrypting the data, as they may still have access to the old version of the key that was used to encrypt the data. You need to also move the min_decryption_version forward to invalidate the old version of the key.
* The Vault administrator would not need to seal the Vault server immediately. Sealing the Vault server would make it inaccessible to both the attacker and the legitimate users, and would require unsealing it with the unseal keys or the recovery keys. Sealing the Vault server is a last resort option in case of a severe compromise or emergency, and is not necessary in this scenario, as the attacker does not have access to the encryption key or the data in Vault.

NEW QUESTION # 143
What command is used to extend the TTL of a token, if permitted?
  • A. vault token renew <token-id>
  • B. vault token revoke <token-id>
  • C. vault capabilities <token-id>
  • D. vault token lookup <token-id>
Answer: A
Explanation:
Comprehensive and Detailed in Depth Explanation:
To extend a token's TTL, the vault token renew command is used. The HashiCorp Vault documentation states: "In order to renew a token, a user can issue a vault token renew command to extend the TTL. The token can also be renewed using the API." It adds: "The vault token renew command extends the Time To Live (TTL) of a token if the policy associated with the token permits renewal." The docs detail: "Tokens have a TTL that determines their validity period. If renewable, the renewcommand can be used before expiration to extend this duration, subject to any max TTL limits."A (revoke)invalidates tokens.B (capabilities)shows permissions, not TTL.C (lookup)displays token info, not extends it. Thus, D is correct.

NEW QUESTION # 144
True or False? Your organization currently runs all of its workloads on Google Cloud Platform (GCP).
Recently, Vault has been deployed, and you need to select an auth method to authenticate your workloads with Vault. Based on this information, GCP is the only auth method that can be used in your environment.
  • A. True
  • B. False
Answer: B
Explanation:
Comprehensive and Detailed In-Depth Explanation:
False. Vault supports multiple auth methods, not just platform-specific ones. The Vault documentation states:
"Just because you are using a certain platform does not mean you need to use the related auth method. Vault offers a variety of auth methods that can be used based on the organization's needs and existing infrastructure, allowing for flexibility and customization in authentication processes."
-Vault Auth Concepts
* B: Correct. Options like AppRole, LDAP, or JWT can be used on GCP:
"GCP auth MIGHT be the best option, but it's not the ONLY option that you can use."
-Vault Auth Concepts
* A: Incorrect; Vault isn't limited to GCP auth on GCP.

NEW QUESTION # 145
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. Policies are only available on Vault Enterprise
  • 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. The policy associated with your login does not permit access to manage policies
Answer: D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
In the Vault UI, the "olicies" 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.
