HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q176-Q181):

NEW QUESTION # 176
You have successfully authenticated using the Kubernetes auth method, and Vault has provided a token. What HTTP header can be used to specify your token when you request dynamic credentials? (Select two)

A. Authorization: Bearer <token>
B. X-Vault-Token: <token>
C. Token: <token>
D. Authentication: <token>

Answer: A,B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
After authenticating with the Kubernetes auth method, Vault returns a token that must be included in subsequent API requests to retrieve dynamic credentials. The Vault documentation specifies two valid HTTP headers for this purpose:
"Once authenticated, most Vault operations require a client token to be set either via the X-Vault-Token header or via the Authorization header using the Bearer type. For example:
* X-Vault-Token: <token>
* Authorization: Bearer <token>"-Vault API Documentation: Authentication
* A: X-Vault-Token: <token> is the primary Vault-specific header for token authentication:
"The X-Vault-Token header is used to specify the token when requesting dynamic credentials from Vault.
This header is commonly used to authenticate and authorize requests to Vault services."
-Vault API Documentation
* D: Authorization: Bearer <token> is a standard HTTP authentication header supported by Vault:
"The Authorization header with the Bearer token format is another common way to specify the token when requesting dynamic credentials from Vault. This header is widely used for authentication purposes in HTTP requests."
-Vault API Documentation
* B: Token: <token> is not a recognized Vault header.
* C: Authentication: <token> is not a standard or supported header in Vault; the correct header is Authorization.
These headers ensure the token is passed securely to Vault for authorizing credential requests.

NEW QUESTION # 177
True or False? Performing a rekey operation using the vault operator rekey command creates new unseal
/recovery keys as well as a new root key?

A. True
B. False

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
False. The vault operator rekey command updates unseal/recovery keys, not the master key (often confused with "root key"). The Vault documentation states:
"The operator rekey command generates a new set of unseal keys. This can optionally change thetotal number of key shares or the required threshold of those key shares to reconstruct the master key. This operation is zero downtime, but it requires that Vault is unsealed and a quorum of existing unseal keys are provided."
-Vault Commands: operator rekey
* B: Correct. Only unseal keys are recreated:
"When performing a rekey operation using the vault operator rekey command, new unseal/recovery keys are generated, but the root key remains the same."
-Vault Commands: operator rekey
* A: Incorrect; the master key persists.

Vault Commands: operator rekey

NEW QUESTION # 178
Which of the following secrets engines does NOT issue a lease upon a read request?

Answer: C

Explanation:
Comprehensive and Detailed in Depth Explanation:
Leases tie to dynamic secrets with TTLs. Let's check:
* A: KV- Static secrets, no lease on read. Correct.
* B: Consul- Dynamic creds with leases. Incorrect.
* C: Database- Dynamic creds with leases. Incorrect.
* D: AWS- Dynamic creds with leases. Incorrect.
Overall Explanation from Vault Docs:
"The Key/Value Backend... does not issue leases although it may return a lease duration." Reference:https://developer.hashicorp.com/vault/docs/concepts/lease#lease-renew-and-revoke

NEW QUESTION # 179

NEW QUESTION # 180
You've set up multiple Vault clusters, one on-premises intended to be the primary cluster, and the second cluster in AWS, which was deployed for performance replication. After enabling replication, developers complain that all the data they've stored in the AWS Vault cluster is missing. What happened?

A. There is a certificate mismatch after replication was enabled since Vault replication generates its own TLS certificates to ensure nodes are trusted entities
B. The data was moved to a recovery path after replication was enabled. Use the vault secrets move command to move the data back to its intended location
C. The data was automatically copied to the primary cluster after replication was enabled since all writes are always forwarded to the primary cluster
D. All of the data on the secondary cluster was deleted after replication was enabled

Answer: D

Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:Certificate issues don't delete data. Incorrect.
* B:Performance replication wipes the secondary's data to sync with the primary. Correct.
* C:Data isn't copied to the primary; replication is one-way. Incorrect.
* D:No recovery path exists; data is wiped. Incorrect.
Overall Explanation from Vault Docs:
"When replication is enabled, all of the secondary's existing storage will be wiped... This is irrevocable." Reference:https://developer.hashicorp.com/vault/tutorials/enterprise/performance-replication
