HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q85-Q90):

NEW QUESTION # 85
You are planning the deployment of your first Vault cluster and have decided to use Integrated Storage as the storage backend. Where do you configure the storage backend to be used by Vault?

A. In the systemd service file
B. In the Vault configuration file
C. In the Vault Agent sink file
D. Inside the Vault service once Vault is up and running

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
The storage backend is configured in the Vault configuration file. The Vault documentation states:
"The Vault configuration file includes different stanzas and parameters to define a variety of configuration options. These configurations include the storage backend, listener, TLS certificates, seal type, cluster name, log level, UI, cluster IP address, and a few more. Most of these are required to get Vault up and running in the first place, so they must be placed in the configuration file."
-Vault Configuration
* C: Correct. For Integrated Storage:
"Configuring the storage backend to be used by Vault is done in the Vault configuration file."
-Vault Configuration: Raft Storage
* A: systemd manages the service, not storage.
* B: Backend must be set before running.
* D: Agent sink is for client tokens.

NEW QUESTION # 86
How does the Vault Secrets Operator (VSO) assist in integrating Kubernetes-based workloads with Vault?

A. By watching for changes to its supported set of Custom Resource Definitions (CRD)
B. By injecting a Vault Agent directly into the pod requesting secrets from Vault
C. By enabling a local API endpoint to allow the workload to make requests directly from the VSO
D. By using client-side caching for KVv1 and KVv2 secrets engines

Answer: A

Explanation:
Comprehensive and Detailed in Depth Explanation:
The Vault Secrets Operator (VSO) integrates Kubernetes workloads with Vault by syncing secrets. Let's evaluate:
* A:VSO doesn't create a local API endpoint for direct requests; it syncs secrets to Kubernetes Secrets.
Incorrect.
* B:Client-side caching is a Vault Agent feature, not VSO's primary function. VSO can use caching, but it's not the main integration method. Incorrect.
* C:VSO doesn't inject Vault Agents; that's a separate Vault Agent Sidecar approach. Incorrect.
* D:VSO watches Custom Resource Definitions (CRDs) to sync Vault secrets to Kubernetes Secrets dynamically. This is its core mechanism. Correct.
Overall Explanation from Vault Docs:
"VSO operates by watching for changes to its supported set of CRDs... It synchronizes secrets from Vault to Kubernetes Secrets, ensuring applications access them natively." Reference:https://developer.hashicorp.com/vault/docs/platform/k8s/vso

NEW QUESTION # 87
What API endpoint is used to manage secrets engines in Vault?

A. /sys/kv
B. /sys/mounts
C. /secret-engines/
D. /sys/capabilities

Answer: B

Explanation:
Comprehensive and Detailed in Depth Explanation:
Vault's API provides endpoints for managing its components, including secrets engines, which generate and manage secrets (e.g., AWS, KV, Transit). Managing secrets engines involves enabling, disabling, tuning, or listing them. Let's evaluate:
* Option A: /secret-engines/This is not a valid Vault API endpoint. Vault uses /sys/ for system-level operations, and no endpoint named /secret-engines/ exists in the official API documentation. It's a fabricated path, possibly a misunderstanding of secrets engine management. Incorrect.
* Option B: /sys/mountsThis is the correct endpoint. The /sys/mounts endpoint allows operators to list all mounted secrets engines (GET), enable a new one (POST to /sys/mounts/<path>), or tune existing ones (POST to /sys/mounts/<path>/tune). For example, enabling the AWS secrets engine at aws/ uses POST /v1/sys/mounts/aws with a payload specifying the type (aws). This endpoint is the central hub for secrets engine management. Correct.
* Option C: /sys/capabilitiesThe /sys/capabilities endpoint checks permissions for a token on specific paths (e.g., what capabilities like read or write are allowed). It's unrelated to managing secrets engines-it'sfor policy auditing, not mount operations. Incorrect.
* Option D: /sys/kvThere's no /sys/kv endpoint. The KV secrets engine, when enabled, lives at a user- defined path (e.g., kv/), not under /sys/. System endpoints under /sys/ handle configuration, not specific secrets engine instances. Incorrect.
Detailed Mechanics:
The /sys/mounts endpoint interacts with Vault's mount table, a registry of all enabled backends (auth methods and secrets engines). A GET request to /v1/sys/mounts returns a JSON list of mounts, e.g., {"kv/": {"type":
"kv", "options": {"version": "2"}}}. A POST request to /v1/sys/mounts/my-mount with {"type": "kv"} mounts a new KV engine. Tuning (e.g., setting TTLs) uses /sys/mounts/<path>/tune. This endpoint's versatility makes it the go-to for secrets engine management.
Real-World Example:
To enable the Transit engine: curl -X POST -H "X-Vault-Token: <token>"
-d '{"type":"transit"}' http://127.0.0.1:8200/v1/sys/mounts/transit. To list mounts: curl -X GET -H "X-Vault- Token:
<token>"
http://127.0.0.1:8200/v1/sys/mounts.
Overall Explanation from Vault Docs:
"The /sys/mounts endpoint is used to manage secrets engines in Vault... List, enable, or tune mounts via this system endpoint." Reference:https://developer.hashicorp.com/vault/api-docs/system/mounts

NEW QUESTION # 88
Select the policies below that permit you to create a new entry of environment=prod at the path /secrets/apps
/my_secret (select three).

A. path "secrets/apps/my_secret" { capabilities = ["update"] }
B. path "secrets/apps/my_secret" { capabilities = ["create"] allowed_parameters = { "environment" = [] } }
C. path "secrets/+/my_secret" { capabilities = ["create"] allowed_parameters = { "*" = [] } }
D. path "secrets/apps/*" { capabilities = ["create"] allowed_parameters = { "environment" = ["dev", "test",
"qa", "prod"] } }

Answer: B,C,D

Explanation:
Comprehensive and Detailed in Depth Explanation:
This question requires identifying Vault policies that allow creating a new entry with environment=prod at the specific path /secrets/apps/my_secret. Vault policies define permissions using paths, capabilities, and parameter constraints. Let's evaluate each option:
* Option A: path "secrets/+/my_secret" { capabilities = ["create"] allowed_parameters = { "*" = []
} }The + wildcard matches any single segment in the path, so this policy applies to /secrets/apps
/my_secret. The create capability permits creating new entries at this path. The allowed_parameters = {
"*" = [] } means any parameter (including environment) can be set to any value. This satisfies the requirement to create an entry with environment=prod. Thus, this policy is correct.
* Option B: path "secrets/apps/my_secret" { capabilities = ["update"] }This policy targets the exact path /secrets/apps/my_secret but only grants the update capability. According to Vault's documentation, update allows modifying existing entries, not creating new ones. Since the question specifies creating a new entry, this policy does not meet the requirement and is incorrect.
* Option C: path "secrets/apps/my_secret" { capabilities = ["create"] allowed_parameters = {
"environment" = [] } }This policy explicitly matches /secrets/apps/my_secret and grants the create capability, which allows new entries to be written. The allowed_parameters = { "environment" = [] } specifies that the environment parameter can take any value (an empty list means no restriction on values). This permits setting environment=prod, making this policy correct.
* Option D: path "secrets/apps/*" { capabilities = ["create"] allowed_parameters = {
"environment" = ["dev", "test", "qa", "prod"] } }The * wildcard matches any path under secrets
/apps/, including /secrets/apps/my_secret. The create capability allows new entries, and the allowed_parameters restricts environment to dev, test, qa, or prod. Since prod is an allowed value, this policy permits creating an entry with environment=prod and is correct.
Overall Explanation from Vault Docs:
Vault policies control access via paths and capabilities (create, read, update, delete, list). The create capability is required to write new data. Parameter constraints (allowed_parameters) further restrict what key-value pairs can be written. An empty list ([]) allows any value, while a populated list restricts values to those specified. A deny takes precedence over any allow, but no deny is present here.

NEW QUESTION # 89
True or False? A token can be renewed up until the max TTL, even if the TTL has been reached.

A. True
B. False

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
This statement isfalse. In HashiCorp Vault, a token's ability to be renewed is governed by itsTTL (Time To Live)andmax TTL (Maximum Time To Live). The TTL represents the current validity period of the token, while the max TTL is the absolute upper limit beyond which the token cannot be extended.
* Token Renewal Mechanics: A token can be renewed only if it has not yet expired (i.e., its TTL has not reached zero). Renewal extends the TTL, but this extension cannot exceed the max TTL configured for the token. The documentation clarifies: "A token can be renewed up until the max TTL as long as the token has not expired. If the token expires (hitting the TTL), the token is revoked and is no longer valid." Once the TTL reaches zero, Vault automatically revokes the token, rendering it unusable and ineligible for renewal.
* Why False?: The phrase "even if the TTL has been reached" implies that renewal is possible after expiration, which contradicts Vault's behavior. After the TTL expires, there is no active token to renew because it has been revoked. Renewal must occur within the active TTL window, and the total lifetime (including renewals) cannot exceed the max TTL.
* Practical Implication: This ensures that tokens have a finite lifecycle, enhancing security by preventing indefinite use of compromised credentials. For example, a token with a TTL of 1 hour and a max TTL of 24 hours can be renewed multiple times within that 24-hour period, but only if renewed before the 1-hour TTL expires each time.
