HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q217-Q222):

NEW QUESTION # 217
You are considering using HCP Vault Dedicated but are concerned about differences between a hosted version and a self-hosted deployment. Which of the following statements is true about HCP Vault Dedicated?

A. HCP Vault Dedicated can be deployed on any cloud provider, including AWS, Azure, and Google Cloud, with full multi-cloud support
B. HCP Vault Dedicated requires different CLI commands and APIs compared to self-hosted Vault Enterprise
C. HCP Vault Dedicated is currently limited to a single region and cannot be deployed across multiple regions
D. HCP Vault Dedicated provides a similar experience to self-hosted Vault Enterprise because it uses the same Vault binary

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
HCP Vault Dedicated is a managed Vault service provided by HashiCorp, designed to mirror the self-hosted Vault Enterprise experience while simplifying deployment:
* A. Same Vault Binary: "HCP Vault Dedicated provides a similar experience to self-hosted Vault Enterprise because it uses the same Vault binary." This ensures consistency in functionality, CLI commands, APIs, and UI interactions, making it familiar to users of self-hosted Vault. The documentation confirms: "HCP Vault Dedicated uses the same binary asself-hosted Vault Enterprise, which means you will have a consistent user experience."
* Incorrect Options:
* B. Multi-Cloud Deployment: HCP Vault Dedicated is a HashiCorp-managed service, not deployable by users on any cloud provider. "It is specifically offered as a hosted solution by HashiCorp and does not support deployment on other cloud platforms." It currently supports AWS and Azure, but not full multi-cloud flexibility.
* C. Different CLI/APIs: The use of the same binary ensures identical CLI and API interfaces.
"Does not require different CLI commands and APIs compared to self-hosted Vault Enterprise."
* D. Single Region Limitation: It supports multiple regions (e.g., North America, Asia, Europe).
"Not limited to a single region and can be deployed across multiple regions." This consistency aids adoption for organizations transitioning to a managed solution.

NEW QUESTION # 218
Your team uses the Transit secrets engine to encrypt all data before writing it to a MySQL database server.
During testing, you manually retrieve ciphertext from the database and decrypt it to ensure the data can be read. After decrypting the data, you are worried something is wrong because the plaintext data isn't legible.
Why can you not read the original plaintext data after decrypting the ciphertext?
* $ vault write transit/decrypt/krausen-key ciphertext=vault:v1:8SDd3WHDOjf7mq69C.....
* Key Value
* --- -----
* plaintext Zml2ZSBzdGFyIHByYWN0aWNlIGV4YW1zIGJ5IGJyeWFuIGtyYXVzZW4=

A. The incorrect key version was used to decrypt the data. Update the ciphertext and change the v1 to v3 to use the latest key version
B. The data was also encrypted on the database. Therefore Vault cannot decrypt the original data
C. The incorrect key was selected when decrypting the ciphertext. Use the correct key to successfully read the data
D. The plaintext is Base64 encoded. Decode the plaintext to see the original data

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:
When using the Transit secrets engine, Vault encrypts data and returns ciphertext (e.g., vault:v1:
<ciphertext>). Upon decryption (e.g., vault write transit/decrypt/<key_name> ciphertext=<value>), Vault returns the plaintext as a Base64-encoded string. This is because the Transit engine supports arbitrary data, including binary files (e.g., PDFs, images), and Base64 encoding ensures safe transport within JSON payloads. If the decrypted output (e.g., Zml2ZSBzdGFyIHByYWN0aWNlIGV4YW1zIGJ5IGJyeWFuIGtyYXVzZW4=) isn't legible, it's not an error-it's Base64 encoded. Decoding it (e.g., using a Base64 decoder) reveals the originalplaintext (e.g.,
"five star practice exams by bryan krausen").
Option A (incorrect key) would cause a decryption failure, not illegible plaintext. Option B (incorrect key version) is irrelevant, as Vault automatically uses the correct version based on the ciphertext's vault:v# prefix, and changing it manually wouldn't produce Base64 output. Option D (database encryption) isn't indicated in the scenario and would also cause a failure, not Base64 output. The Transit documentation explicitly states that plaintext is returned Base64-encoded, requiring the user to decode it.

NEW QUESTION # 219
You need to connect to and manage a new HCP Vault cluster using the Vault CLI on your laptop. What environment variables should you set to establish connectivity?

A. VAULT_NAMESPACE=root, VAULT_REDIRECT_ADDR=<cluster-address>
B. VAULT_ADDR=https://<cluster-address>:8200, VAULT_NAMESPACE=admin
C. VAULT_TOKEN=<token-here>, VAULT_CLUSTER_ADDR=https://<cluster-address>:8200
D. VAULT_CLIENT_KEY=<path-to-key-file>, VAULT_TOKEN=<token-here>

Answer: B

Explanation:
Comprehensive and Detailed in Depth Explanation:
To connect to an HCP Vault cluster using the Vault CLI, you need to setVAULT_ADDRand VAULT_NAMESPACE. The HashiCorp Vault documentation states: "You can use environment variables to configure the CLI globally. For example, export VAULT_ADDR='http://localhost:8200' sets the address of your Vault server globally." For HCP Vault, the default port is 8200, and the default namespace is "admin," so VAULT_ADDR=https://<cluster-address>:8200 and VAULT_NAMESPACE=admin are required. A token (via VAULT_TOKEN) is also needed for authentication but is typically set after initial connectivity.
VAULT_CLIENT_KEYisn't a standard variable for CLI connectivity.VAULT_REDIRECT_ADDRand VAULT_CLUSTER_ADDRare not used for this purpose. Thus, C provides the correct variables.

NEW QUESTION # 220
After creating a dynamic credential on a database, the DBA accidentally deletes the credentials on the database itself. When attempting to remove the lease, Vault returns an error stating that the credential cannot be found. What command can be run to make Vault remove the secret?

A. vault lease -renew
B. vault lease revoke -force -prefix <lease_path>
C. vault lease revoke -enforce
D. vault revoke -apply

Answer: B

Explanation:
Comprehensive and Detailed in Depth Explanation:
When a dynamic credential is deleted externally, Vault may fail to revoke the lease due to the missing backend secret. The HashiCorp Vault documentation states: "The -force flag is meant for recovery situations where the secret in the target platform was manually removed." The command vault lease revoke -force - prefix <lease_path> allows Vault to forcibly revoke all leases under the specified prefix, bypassing the error.
The docs elaborate: "Using -force with -prefix will revoke all leases that match the given prefix, even if the underlying secrets cannot be found or revoked on the target system. This is useful for cleaning up Vault's lease table when external changes disrupt normal revocation." Here, <lease_path> would be the path like database/creds/role/.B (vault lease -renew)renews leases, not removes them.C (-enforce)is not a valid flag.D (vault revoke -apply)is incorrect syntax. Thus, A is correct.

HashiCorp Vault Documentation - Lease Revoke Command: Force

NEW QUESTION # 221
Which of the following best describes a token accessor?

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

Answer: D

Explanation:
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.
