HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q117-Q122):

NEW QUESTION # 117
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. 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
B. There is a certificate mismatch after replication was enabled since Vault replication generates its own TLS certificates to ensure nodes are trusted entities
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

NEW QUESTION # 118
Although batch and service tokens share many characteristics, which of the following are true only about batch tokens? (Select three)

A. They are not persisted to disk
B. Are renewable up until the max TTL
C. They are valid for either the primary or any secondary clusters
D. Maintain a single fixed TTL
E. Can create child tokens

Answer: A,C,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Batch and service tokens differ in key ways, with these unique tobatch tokens:
* C. Maintain a single fixed TTL: "Batch tokens maintain a single fixed TTL," non-renewable, unlike service tokens.
* D. Valid across clusters: "They are valid for either the primary or any secondary clusters," enhancing flexibility in replicated setups.
* E. Not persisted to disk: "Batch tokens are not persisted to disk," reducing exposure risk.
* Incorrect Options:
* A. Can create child tokens: "Batch tokens cannot create child tokens," unlike service tokens.
* B. Renewable: "Batch tokens are not renewable," a key distinction from service tokens.
Batch tokens prioritize lightweight, ephemeral use.

NEW QUESTION # 119
You are using Vault to generate dynamic credentials for a Microsoft SQL server to perform queries for a month-end report. The report seems to be taking much longer than expected due to degradation on the underlying server, and you are afraid that Vault might automatically revoke the credentials. How can you extend the time the credentials are valid to ensure your month-end query is successful?

A. Renew the lease
B. Revoke the lease
C. Create a new role within the secrets engine for the database
D. Generate a new lease

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Dynamic credentials have a lease with a TTL, after which Vault revokes them. To extend their validity, you renew the lease. The Vault documentation states:
"If a lease has been created in Vault, it has an associated TTL in which it will expire and be revoked. If the lease needs to be extended for some reason, you can use the command vault lease renew <lease_id> to extend the TTL of the lease so it will not expire at its original TTL and will be extended by the time specified in seconds from the current time the lease renewal was issued."
-Vault Commands: lease renew
* A: Correct. Renewing the lease (e.g., vault lease renew <lease_id>) extends the TTL:
"Renewing the lease of the dynamic credentials in Vault allows you to extend the validity period without having to generate new credentials."
-Vault Commands: lease renew
* B: Generating a new lease creates new credentials, disrupting the query.
* C: Creating a new role doesn't extend existing credentials' TTL.
* D: Revoking the lease terminates the credentials, halting the query.

Vault Commands: lease renew

NEW QUESTION # 120
True or False? Once you create a KV v1 secrets engine and place data in it, there is no way to modify the mount to include the features of a KV v2 secrets engine.

A. False
B. True

Answer: A

Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:Incorrect; KV v1 can be upgraded to v2.
* B:Correct; vault kv enable-versioning upgrades it.
Overall Explanation from Vault Docs:
"kv enable-versioning turns on versioning for an existing KV v1 engine at its path." Reference:https://developer.hashicorp.com/vault/docs/secrets/kv/kv-v2#upgrading-from-version-1

NEW QUESTION # 121
An application has authenticated to Vault and has obtained dynamic database credentials with a lease of 4 hours. Four hours later, the credentials expire, and the application can no longer communicate with the backend database, so the application goes down. What should the developers instruct the application to do to prevent this from happening again while maintaining the same level of security?

A. Go back to using static credentials
B. Use a different auth method
C. Renew the lease before expiration
D. Revoke the lease before expiration

Answer: C

Explanation:
Comprehensive and Detailed in Depth Explanation:
To prevent application downtime due to expired dynamic credentials while maintaining security, the application should renew the lease before it expires. The HashiCorp Vault documentation states: "The application should frequently 'check-in' with Vault and renew the lease to prevent the lease from expiring." It adds: "A lease must be renewed before it has expired. Once it has expired, it is permanently revoked and a new secret must be requested." The docs elaborate: "Dynamic secrets are designed to be short-lived and automatically rotated or revoked when their lease expires. Renewing the lease extends its validity, ensuring continuous access without compromising the security benefits of short-lived credentials."A (Static credentials)reduces security by eliminating rotation.C (Revoke)ends access early.D (Different auth method)doesn't address lease management. Thus, B is correct.
