HashiCorp Certified: Vault Associate (003)Exam HCVA0-003 Prüfungsfragen mit Lösungen (Q195-Q200):

195. Frage
Which of the following best describes a token accessor?

A. A token used for clients to access Vault secrets engines
B. Describes the value associated with the token's TTL
C. A value that describes which clients have access to the attached token
D. A value that acts as a reference to a token which can be used to perform limited actions against the token

Antwort: D

Begründung:
Comprehensive and Detailed in Depth Explanation:
A token accessor is a unique identifier linked to a token, used for management purposes. The HashiCorp Vault documentation states: "A token accessor is created alongside of each token, and the accessor can be used to perform limited actions against the token, including looking up the token's properties, renewing the token, and even revoking the token." It acts as a reference, not the token itself, enabling specific operations without exposing the token's value.
The docs further clarify: "Token accessors provide a way to interact with a token without needing the token itself, enhancing security by limiting direct exposure." Option A misattributes access control, B ties it to TTL (unrelated), and C confuses it with the token. Thus, D accurately describes its role.

196. Frage
You have a long-running app that cannot handle a regeneration of a token or secret. What type of token should be created for this application in order to authenticate and interact with Vault?

A. Orphan Token
B. Batch Token
C. Service Token with Use Limit
D. Periodic Service Token

Antwort: D

Begründung:
Comprehensive and Detailed in Depth Explanation:
For a long-running application that cannot handle token or secret regeneration, thePeriodic Service Tokenis the most suitable choice. According to HashiCorp Vault documentation, periodic service tokens are renewable tokens that do not have a maximum Time-to-Live (TTL), meaning they can be renewed indefinitely by the client without requiring manual intervention or regeneration. This is ideal for applications needing continuous access to Vault over an extended period. The documentation states: "Periodic tokens have a TTL, but no max TTL. Periodic tokens may live for an infinite amount of time, so long as they are renewed within their TTL." This feature ensures uninterrupted operation for long-running processes, aligning perfectly with the scenario described.
In contrast, aService Token with Use Limithas a finite number of uses before expiration, making it unsuitable for continuous access without regeneration. ABatch Tokenis designed for short-lived, one-time operations or batch processes, not persistent access, as it lacks renewability and has a fixed TTL. AnOrphan Token, while not tied to a parent token, does not inherently address the regeneration issue and is less secure for long-term use due to its lack of association with policies or identity. Thus, the periodic service token stands out as the best fit.

197. Frage
The vault lease renew command increments the lease time from:

A. The current time
B. The end of the lease

Antwort: A

Begründung:
The vault lease renew command increments the lease time from the current time, not the end of the lease. This means that the user can request a specific amount of time they want remaining on the lease, termed the increment. This is not an increment at the end of the current TTL; it is an increment from the current time. For example, vault lease renew -increment=3600 my-lease-id would request that the TTL of the lease be adjusted to 1 hour (3600 seconds) from now. Having the increment be rooted at the current time instead of the end of the lease makes it easy for users to reduce the length of leases if they don't actually need credentials for the full possible lease period, allowing those credentials to expire sooner and resources to be cleaned up earlier.
The requested increment is completely advisory. The backend in charge of the secret can choose to completely ignore it1. References:

198. Frage
When Vault is sealed, which are the only two operations available to a Vault administrator? (Select two)

A. Author security policies
B. Unseal Vault
C. Rotate the encryption key
D. View the status of Vault
E. View data stored in the key/value store
F. Configure policies

Antwort: B,D

Begründung:
Comprehensive and Detailed in Depth Explanation:
When Vault is sealed, its functionality is severely restricted to protect encrypted data. The HashiCorp Vault documentation states: "While Vault is sealed, the only two options available are viewing the vault status (vault status) and unsealing Vault (vault operator unseal). All the other actions require Vault to be unsealed and the user to be authenticated." This limitation ensures that no operations can access or modify data until the Vault is unsealed, enhancing security.
The documentation under "Shamir Seals" further elaborates: "When Vault is sealed, it knows where its encrypted data is stored but cannot decrypt it because the master key is not in memory. The only available operations are checking the seal status and initiating the unseal process." Thus:
* A (View the status of Vault): The vault status command works when sealed, providing details like seal state.
* E (Unseal Vault): The vault operator unseal command allows administrators to begin unsealing.
Options likeconfigure policies (B),view data in the key/value store (C),rotate the encryption key (D), and author security policies (F)require an unsealed Vault and authentication, making A and E the correct selections.

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

Antwort: A,C,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.
