HashiCorp Certified: Vault Associate (003)Exam HCVA0-003 Prüfungsfragen mit Lösungen (Q133-Q138):

133. Frage
You are the primary Vault operator. During a routine audit, an auditor requested the ability to display all secrets under a specific path in Vault without seeing the actual stored data. Which policy permits the auditor to display the stored secrets without revealing their contents?

A. path "kv/apps/+/" { capabilities = ["list"] }
B. path "kv/+/production" { capabilities = ["list"] }
C. path "kv/apps/production/" { capabilities = ["list"] }
D. path "kv/apps/*" { capabilities = ["list", "read"] }

Antwort: B

Begründung:
Comprehensive and Detailed In-Depth Explanation:
The list capability allows viewing secret names without data. The Vault documentation states:
"The list capability is required to list keys at a path without necessarily being able to read the data at those paths. The + symbol is a directory replacement and ANY value would be permitted in that path segment."
-Vault Policies: Capabilities
-Vault Policies: Policy Syntax
* C: Correct. Lists all secrets under kv/<anything>/production:
"This policy allows the auditor to list all secrets under the specified path kv/+/production without being able to read the actual stored data."
-Vault Policies: Capabilities
* A,B: Too narrow, missing some secrets.
* D: Includes read, exposing data.
References:
Vault Policies: Capabilities
Vault Policies: Policy Syntax

134. Frage
You have a 2GB Base64 binary large object (blob) that needs to be encrypted. Which of the following best describes the transit secrets engine?

A. The transit engine is not a good solution for binaries of this size.
B. Vault will store the blob permanently. Be sure to run Vault on a compute optimized machine
C. To process such a large blob. Vault will temporarily store it in the storage backend.
D. A data key encrypts the blob locally, and the same key decrypts the blob locally.

Antwort: A

Begründung:
The transit secrets engine is not a good solution for binaries of this size, because it is designed to handle cryptographic functions on data in-transit, not data at-rest. The transit secrets engine does not store any data sent to it, so it would require sending the entire 2GB blob to Vault for encryption or decryption, which would be inefficient and impractical. A better solution would be to use the transit secrets engine to generate a data key, which is a high-entropy key that can be used to encrypt or decrypt data locally. The data key can be returned in plaintext or wrapped by another key, depending on the use case. This way, the transit secrets engine only handles the encryption or decryption of the data key, not the data itself, and the data can be stored in any primary data store.

135. Frage
Although batch and service tokens share many characteristics, which of the following are true only about batch tokens? (Select three)

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

Antwort: B,C,E

Begründung:
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.

136. Frage
Julie is a developer who needs to ensure an application can properly renew its lease for AWS credentials it uses to access data in an S3 bucket. Although the application would generally use the API, what is the equivalent CLI command to perform this action?

A. vault lease renew aws/roles/s3-read-only/39e6b9a2-296-83d9-2fe0-c11e846bdc99
B. vault lease renew aws/creds/s3-read-only/39e6b9a2-296-83d9-2fe0-c11e846bdc99
C. vault renew aws/roles/s3-read-only/39e6b9a2-296-83d9-2fe0-c11e846bdc99
D. vault lease renew aws/creds/s3-read-only

Antwort: B

Begründung:
Comprehensive and Detailed In-Depth Explanation:
To renew AWS credential leases:
* B. Correct: "The proper command would be vault lease renew aws/creds/s3-read-only/39e6b9a2-296-
83d9-2fe0-c11e846bdc99." Targets the credential lease ID.
* Incorrect Options:
* A, C: Wrong path (roles vs. creds).
* D: Missing lease ID.

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

Antwort: A,B,D

Begründung:
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.
