HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q220-Q225):

NEW QUESTION # 220
True or False? When encrypting data with the Transit secrets engine, Vault always stores the ciphertext in a dedicated KV store along with the associated encryption key.

  • A. False
  • B. True

Answer: A

Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:Incorrect. Transit doesn't store ciphertext; it returns it to the client.
* B:Correct. The Transit engine performs encryption/decryption without persisting data.
Overall Explanation from Vault Docs:
"The Vault Transit secrets engine does NOT store any data... Ciphertext is returned to the caller." Reference:https://developer.hashicorp.com/vault/docs/secrets/transit


NEW QUESTION # 221
From the options below, select the benefits of using the PKI (x.509 certificates) secrets engine (select three):

  • A. Reducing, or eliminating certificate revocations
  • B. Vault can act as an intermediate CA
  • C. Reduces time to get a certificate by eliminating the need to generate a private key and CSR
  • D. TTLs on Vault certs are longer to ensure certificates are valid for a longer period of time

Answer: A,B,C

Explanation:
Comprehensive and Detailed in Depth Explanation:
ThePKI secrets enginein Vault generates dynamic X.509 certificates, acting as a certificate authority (CA) to streamline certificate management. Let's assess each option based on its documented benefits:
* Option A: TTLs on Vault certs are longer to ensure certificates are valid for a longer period of timeThis is misleading. Vault's PKI engine allows configurable TTLs, but the recommendation is for short TTLs(e.g., hours or days) to reduce the need for revocation and enhance security. Long TTLs increase exposure if a certificate is compromised, requiring revocation and larger Certificate Revocation Lists (CRLs). The engine's benefit isn't longer validity-it's flexibility and automation, not extended lifetimes. Incorrect.Vault Docs Insight:"By keeping TTLs relatively short, revocations are less likely... helping scale to large workloads." (Short TTLs are preferred.)
* Option B: Reducing, or eliminating certificate revocationsA key advantage of the PKI engine is issuing short-lived certificates. With short TTLs (e.g., 24h), certificates expire naturally before revocation is needed, minimizing CRL maintenance. For example, an app can fetch a new cert daily, reducing revocation events compared to traditional multi-year certs. This aligns with Vault's ephemeral certificate model. Correct.Vault Docs Insight:"By keeping TTLs relatively short, revocations are less likely to be needed, keeping CRLs short..." (Direct benefit.)
* Option C: Reduces time to get a certificate by eliminating the need to generate a private key and CSRTraditionally, obtaining a certificate involves generating a private key, creating a Certificate Signing Request (CSR), and submitting it to a CA-a manual, time-consuming process. The PKI engine automates this: vault write pki/issue/my-role common_name=app.example.com instantly generates a private key and signed certificate. This eliminates manual steps, speeding up issuance significantly. Correct.Vault Docs Insight:"Services can get certificates without... generating a private key andCSR, submitting to a CA, and waiting..." (Automation reduces time.)
* Option D: Vault can act as an intermediate CAThe PKI engine can be configured as an intermediate CA, signed by a root CA (internal or external). For example, vault write pki/intermediate/generate
/internal common_name="Intermediate CA" creates an intermediate, which can issue certificates under a trust chain. This supports hierarchical PKI setups, a major feature. Correct.Vault Docs Insight:"The PKI secrets engine can act as an intermediate CA... issuing certificates on behalf of a root CA." (Explicit capability.) Detailed Mechanics:
The PKI engine operates at paths like pki/ (root) or pki_int/ (intermediate). Roles (e.g., my-role) define parameters like TTL and allowed domains. Issuing a cert (vault write pki/issue/my-role...) returns a JSON payload with certificate, private_key, and issuing_ca. Short TTLs leverage Vault's lease system, auto- revoking certs on expiry. As an intermediate CA, it signs certificates with its key, validated against a root, enhancing trust management.
Real-World Example:
An app needs a cert: vault write pki/issue/web common_name=web.example.com ttl=24h. Vault returns a cert and key instantly, valid for 24 hours. No CSR, no revocation needed-expires tomorrow. Another PKI mount at pki_int/ issues certs under a corporate root CA.
Overall Explanation from Vault Docs:
"The PKI secrets engine generates dynamic X.509 certificates... Services can get certificates without the usual manual process... By keeping TTLs short, revocations are less likely... Vault can act as an intermediate CA, issuing certificates efficiently." These benefits-automation, reduced revocation, and CA flexibility- define its value.

NEW QUESTION # 222
How would you describe the value of using the Vault transit secrets engine?

  • A. Encryption for application data is best handled by a storage system or database engine, while storing encryption keys in Vault
  • B. The transit secrets engine relieves the burden of proper encryption/decryption from application developers and pushes the burden onto the operators of Vault
  • C. Vault has an API that can be programmatically consumed by applications
  • D. The transit secrets engine ensures encryption in-transit and at-rest is enforced enterprise wide

Answer: B

Explanation:
The transit secrets engine relieves the burden of proper encryption/decryption from application developers and pushes the burden onto the operators of Vault. The transit secrets engine provides encryption as a service, which means that it performs cryptographic operations on data in-transit without storing any data. This allows developers to delegate the responsibility of managing encryption keys and algorithms to Vault operators, who can define and enforce policies on the transit secrets engine. This way, developers can focus on their application logic and data, while Vault handles the encryption and decryption of data in a secure and scalable manner.

NEW QUESTION # 223
You have multiple Vault clusters in your environment, one for test and one for production. You have the CLI installed on your local machine and need to target the production cluster to make configuration changes. What environment variable can you set to target the production cluster?

  • A. VAULT_CLUSTER_ADDR
  • B. VAULT_REDIRECT_ADDR
  • C. VAULT_CAPATH
  • D. VAULT_ADDR

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
The VAULT_ADDR variable specifies the target Vault server. The Vault documentation states:
"VAULT_ADDR is the environment variable that is used to specify the address of the Vault server expressed as a URL and port, for example: https://vault.bryankrausen.com:8200/. You can easily modify the value of the environment variable whenever you want to target a different Vault node/cluster."
-Vault Environment Variables
* C: Correct. Sets the production cluster address:
"Setting the VAULT_ADDR environment variable allows you to specify the address of the Vault server you want to target."
-Vault Environment Variables
* A,B,D: Incorrect; unrelated to CLI targeting.

NEW QUESTION # 224
Which of the following is a machine-oriented Vault authentication backend?

  • A. GitHub
  • B. Okta
  • C. AppRole
  • D. Transit

Answer: C

Explanation:
AppRole is a machine-oriented authentication method that allows machines or applications to authenticate with Vault using a role ID and a secret ID. The role ID is a unique identifier for the application, and the secret ID is a single-use credential that can be delivered to the application securely. AppRole is designed to provide secure introduction of machines and applications to Vault, and to support the principle of least privilege by allowing fine-grained access control policies to be attached to each role1.
Okta, GitHub, and Transit are not machine-oriented authentication methods. Okta and GitHub are user- oriented authentication methods that allow users to authenticate with Vault using their Okta or GitHub credentials23. Transit is not an authentication method at all, but a secrets engine that provides encryption as a service4.
