HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q201-Q206):

NEW QUESTION # 201
By default, what happens to child tokens when a parent token is revoked?

A. The child tokens are converted to parent tokens
B. The child tokens are revoked
C. The child tokens are renewed
D. The child tokens create their own child tokens to be used

Answer: B

Explanation:
Comprehensive and Detailed in Depth Explanation:
By default, when a parent token is revoked, all child tokens are also revoked. The HashiCorp Vault documentation (via support article) states: "When a parent token is revoked, all of its child tokens-and all of their leases-are revoked as well. This ensures that a user cannot escape revocation by simply generating a never-ending tree of child tokens." This hierarchical revocation ensures security by terminating all derived access when the parent is invalidated.
The documentation on tokens adds: "Tokens in Vault are part of a hierarchy. Child tokens inherit properties from their parents, and revoking a parent token cascades to its children." Options like renewal, conversion to parent tokens, or creating new child tokens do not occur by default. Thus, A is correct.

HashiCorp Support - Parent-Child Token Hierarchy
HashiCorp Vault Documentation - Tokens

NEW QUESTION # 202
You have multiple Kubernetes pods that need frequent access to Vault to retrieve credentials for establishing connectivity to a backend database. You enable the Kubernetes auth method in Vault. What resource do you need to create within Kubernetes to complete this configuration?

A. k8s service account token
B. Username and password for kubectl
C. A Vault token for authentication
D. An AppRole role_id and secret_id

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Kubernetes auth requires:
* B. k8s service account token: "The kubernetes auth method can be used to authenticate with Vault using a Kubernetes Service Account Token."
* Incorrect Options:
* A, C, D: Not specific to Kubernetes auth.
Reference:https://developer.hashicorp.com/vault/docs/auth/kubernetes

NEW QUESTION # 203
You need to decrypt customer data to provide it to an application. When you run the decryption command, you get the output below. Why does the response not directly reveal the cleartext data?
$ vault write transit/decrypt/phone_number ciphertext="vault:v1:tgx2vsxtlQRfyLSKvem..." Key Value
--- -----
plaintext aGFzaGljb3JwIGNlcnRpZmllZDogdmF1bHQgYXNzb2NpYXRl

A. The output is base64 encoded
B. The output is actually a response wrapped token that needs to be unwrapped
C. The user does not have permission to view the cleartext data
D. The original data must have been encrypted

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
The Vault Transit secrets engine returns decrypted data inbase64-encoded format:
* B. The output is base64 encoded: "All plaintext data must be base64-encoded before being encrypted by Vault. As a result, decrypted data is always base64 encoded." Users must decode it (e.g., using base64 -d) to see cleartext.
* Incorrect Options:
* A. Permission Issue: Permissions would cause an error, not encoded output. "Not because the user lacks permission."
* C. Wrapped Token: The output is plaintext, not a token. "Not a response wrapped token."
* D. Original Encryption: Irrelevant; the issue is encoding, not encryption state.
This encoding ensures safe transmission of binary data.

NEW QUESTION # 204
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?

A. Add performance standby nodes
B. Enable control groups
C. Add additional standby nodes
D. Enable multiple secrets engines for the applications

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:
To address performance issues from heavy read access, Vault Enterprise offersperformancestandby 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.

NEW QUESTION # 205
Vault operators can create two types of groups in Vault. What are the two types?

A. Internal groups
B. Security groups
C. Policy groups
D. External groups

Answer: A,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
In HashiCorp Vault, operators can create two distinct types of groups within the Identity secrets engine:
external groupsandinternal groups. These groups are used to manage and organize users and policies, facilitating access control and permissions management.
* External Groups: These groups are designed to integrate with external identity providers or systems, such as LDAP or OIDC (OpenID Connect). External groups allow Vault to map groups from these external systems to Vault policies, enabling seamless access control for users authenticated via external auth methods. They can be created manually or automatically mapped (e.g., from LDAP group memberships to Vault policies). This is particularly useful when managing users who exist outside of Vault's internal identity store but need access to Vault resources. The documentation states: "External groups are usually associated with an auth method, such as LDAP or OIDC."
* Internal Groups: These are created and managed directly within Vault's identity store. Internal groups are used to organize Vault entities (representing users or machines) and assign policies to them manually. They are ideal for scenarios where user management is entirely within Vault's ecosystem, without reliance on external identity providers. The documentation explains: "Internal groups are created in the identity store and map to other groups or entities."
* Incorrect Options:
* Security Groups: This term is not used in Vault's context for group types. While security is a core concern, "security groups" do not represent a specific category of groups in Vault.
* Policy Groups: Policies in Vault define permissions, but there is no concept of "policy groups" as a distinct group type. Policies are attached to groups, not grouped themselves in this manner.
The distinction between external and internal groups enhances flexibility in managing authentication and authorization, aligning with Vault's design to support both internal and federated identity systems.
