HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q116-Q121):

NEW QUESTION # 116
Mike's Cereal Shack uses Vault to encrypt customer data to ensure it is always stored securely. They are developing a new application integration to send new customer data to be encrypted using the following API request:
text
CollapseWrapCopy
$ curl \
--header "X-Vault-Token: hvs.sf4vj1rFV5PvQSV3M9dcv832brxQFsfbXA" \
--request POST \
--data @data.json \
https://vault.mcshack.com:8200/v1/transit/encrypt/customer-data
What would be contained within the data.json file?

Answer: A

Explanation:
Comprehensive and Detailed in Depth Explanation:
The data.json file in this API request contains the data to be encrypted by the Transit secrets engine. The HashiCorp Vault documentation states: "When executing any call to the Vault API, data can be sent using an external file as shown above. In this case, the contents of the file would be cleartext customer data that needs to be encrypted by the transit secrets engine." Specifically, for the /transit/encrypt/ endpoint, it explains: "The API expects a JSON payload with a plaintext field containing the base64-encoded data to encrypt." The documentation elaborates under "Encrypt Data": "The request body must include the plaintext parameter, which is the base64-encoded version of the data you want to encrypt. For example: {"plaintext": "base64- encoded-data"}." Here,D (Cleartext customer data to be encrypted)fits this requirement-customer data in cleartext, base64-encoded, sent for encryption.A (Transit config)is managed in Vault, not sent.B (Ciphertext) is the output, not input.C (Encryption key)is stored in Vault, not provided by the client. Thus, D is correct.

NEW QUESTION # 117
Which of the following is a reason to rekey a Vault cluster?
Pick the 2 correct responses below.

Answer: C,E

Explanation:
Rekeying is used when the unseal or recovery key custody model must change. If a keyholder joins or leaves the organization, the existing shares should no longer be trusted as the active quorum, so rekeying creates a new set of key shares and can change the threshold. A compliance requirement to refresh the key material used to reconstruct the root key is also a valid rekey driver. Adding more Vault nodes does not require rekeying because storage clustering and seal key custody are separate concerns. Upgrading editions does not inherently require new key shares. If the root token is lost, the proper operation is root-token generation using a quorum, not rekeying. HashiCorp documents vault operator rekey as the command that generates a new set of unseal keys and can change key shares or threshold.


NEW QUESTION # 118
After creating a dynamic credential on a database, the DBA accidentally deletes the credentials on the database itself. When attempting to remove the lease, Vault returns an error stating that the credential cannot be found. What command can be run to make Vault remove the secret?

Answer: A

Explanation:
Comprehensive and Detailed in Depth Explanation:
When a dynamic credential is deleted externally, Vault may fail to revoke the lease due to the missing backend secret. The HashiCorp Vault documentation states: "The -force flag is meant for recovery situations where the secret in the target platform was manually removed." The command vault lease revoke -force - prefix <lease_path> allows Vault to forcibly revoke all leases under the specified prefix, bypassing the error.
The docs elaborate: "Using -force with -prefix will revoke all leases that match the given prefix, even if the underlying secrets cannot be found or revoked on the target system. This is useful for cleaning up Vault's lease table when external changes disrupt normal revocation." Here, <lease_path> would be the path like database/creds/role/.B (vault lease -renew)renews leases, not removes them.C (-enforce)is not a valid flag.D (vault revoke -apply)is incorrect syntax. Thus, A is correct.
Reference:
HashiCorp Vault Documentation - Lease Revoke Command: Force


NEW QUESTION # 119
Which is true about Vault authentication responses when using the Vault API?

Answer: B

Explanation:
When a client authenticates to Vault through the API, Vault returns a client token. That token is then used to authorize later API requests. Unlike the CLI and UI, the raw HTTP API does not automatically remember or reuse the token for the client. The caller must explicitly send the token in the request header, normally as X- Vault-Token: < token > or as a bearer token. Option A is false because Vault authentication can be performed through the API. Option B is false because most useful Vault API endpoints require authentication. Option C is wrong because deleting the token would prevent further authenticated requests. HashiCorp's token authentication documentation confirms that API authentication requires passing the token in the request header.


NEW QUESTION # 120
Your organization has many applications needing heavy read access to Vault. As these applications integrate with Vault, the primary Vault cluster's performance is negatively impacted. What feature can you use to scale the cluster and improve performance?

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
To address performance issues from heavy read access, Vault Enterprise offers performance standby nodes :
* D. Add performance standby nodes : These nodes handle read-only requests locally, offloading the primary cluster. " Vault Enterprise offers additional features that allow HA nodes to service read-only requests on the local standby node, " improving scalability and performance.
* Incorrect Options :
* A. Additional Standby Nodes : Standard HA standby nodes focus on failover, not read scaling. " May help with high availability, but not directly address performance. "
* B. Multiple Secrets Engines : Organizes secrets but doesn't scale read performance. " Does not directly address performance issues. "
* C. Control Groups : A resource management feature, not for scaling Vault. " Not directly related to scaling the Vault cluster. " Performance standby nodes distribute read workloads effectively in Vault Enterprise.
