HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q278-Q283):

NEW QUESTION # 278
What could you do with the feature found in the screenshot below (select two)?

A. Encrypt sensitive data to send to a colleague over email
B. Encrypt the Vault master key that is stored in memory
C. Using a short TTL, you could encrypt data in order to place only the encrypted data in Vault
D. Use response-wrapping to protect data

Answer: A,D

Explanation:
Comprehensive and Detailed in Depth Explanation:
The screenshot highlights Vault'sresponse wrappingfeature, accessible via the UI's "Wrap" option. This feature wraps a Vault response (e.g., a secret or token) in a single-use token with a configurable TTL, ensuring secure delivery to an intended recipient. Let's evaluate each option against this capability:
* Option A: Using a short TTL, you could encrypt data in order to place only the encrypted data in VaultThis misinterprets response wrapping. Wrapping doesn't encrypt data for storage in Vault; it secures a response for transmission outside Vault. Encryption for storage would involve the Transit secrets engine, not wrapping. The TTL in wrapping limits the wrapped token's validity, not the data's encryption lifecycle. This option conflates two unrelated features and is incorrect.Vault Docs Insight:
"Response wrapping does not store data in Vault; it delivers it securely to a recipient." (No direct storage implication.)
* Option B: Encrypt the Vault master key that is stored in memoryThe master key in Vault is already encrypted at rest (in storage) and decrypted in memory during operation using the unseal process (e.g., Shamir shares or auto-unseal). Response wrapping doesn't interact with the master key-it's a client- facing feature for secret delivery, not an internal encryption mechanism. This is a fundamental misunderstanding of Vault's architecture and wrapping's purpose. Incorrect.Vault Docs Insight:"The master key is managed by the seal mechanism, not client-facing features like wrapping." (See seal
/unseal docs.)
* Option C: Encrypt sensitive data to send to a colleague over emailThis aligns perfectly with response wrapping. You can retrieve a secret (e.g., vault read secret/data/my-secret), wrap it with a short TTL (e.g., 5 minutes), and receive a token (e.g., hvs.<token>). You email this token to a colleague, who unwraps it with vault unwrap <token> to access the secret. The data is encrypted within the token, secure during transit, and expires after the TTL. This is a textbook use case for wrapping.
Correct.Vault Docs Insight:"Response wrapping... can be used to securely send sensitive data to another party, such as over email, with a limited lifetime." (Directly supported use case.)
* Option D: Use response-wrapping to protect dataThis is the essence of the feature. Wrapping protects data by encapsulating it in a single-use token, accessible only via an unwrap operation. For example, vault write -wrap-ttl=60s secret/data/my-secret returns a wrapped token, protecting the secret until unwrapped. This ensures confidentiality and controlled access, making it a core benefit of the feature. Correct.Vault Docs Insight:"Vault can wrap a response in a single-use token... protecting the data until unwrapped by the recipient." (Core definition.) Detailed Mechanics:
Response wrapping works by taking a Vault API response (e.g., a secret's JSON payload) and storing it in the cubbyholesecrets engine under a newly generated single-use token. The token's TTL (e.g., 60s) limits its validity. The API call POST /v1/sys/wrapping/wrap with a payload (e.g., {"ttl": "60s", "data": {"key":
"value"}}) returns {"wrap_info": {"token": "hvs.<token>"}}. The recipient uses vault unwrap hvs.<token> (or POST /v1/sys/wrapping/unwrap) to retrieve the original data. Once unwrapped, the token is revoked, ensuring one-time use. This leverages Vault'sencryption and token system for secure data exchange.
Real-World Example:
You generate an API key in Vault: vault write secret/data/api key=abc123. In the UI, you click "Wrap" with a
5-minute TTL, getting hvs.XYZ. You email hvs.XYZ to a colleague, who runs vault unwrap hvs.XYZ within
5 minutes to get key=abc123. After unwrapping, the token is invalid, and the secret is safe from interception.
Overall Explanation from Vault Docs:
"Vault includes a feature called response wrapping. When requested, Vault can take the response it would have sent to an HTTP client and instead insert it into the cubbyhole of a single-use token, returning that token instead... This is useful for securely delivering sensitive data." The feature excels at protecting data in transit (e.g., email) and enforcing one-time access, not internal key management or storage encryption.

NEW QUESTION # 279
A DevOps engineer has set up LDAP and GitHub auth methods. The engineer must ensure user Sarah, who authenticates via either method, has consistent access permissions. Which approach correctly describes how to achieve this in Vault?

A. Create separate policies for each auth method and manually ensure they remain synchronized
B. Create an entity for Sarah and map both her LDAP and GitHub identities as entity aliases to this single entity
C. Create an external group and add the LDAP and GitHub providers as members of the group
D. Configure a trust relationship between the LDAP and GitHub providers to ensure Sarah's account is synced

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:
To ensure consistent access permissions for Sarah across multiple authentication methods (LDAP and GitHub), the correct approach in Vault is tocreate an entity for Sarah and map both her LDAP and GitHub identities as entity aliases to this single entity.
* Entities and Aliases in Vault: Vault's Identity secrets engine allows the creation of entities, which are logical representations of users or machines. Each entity can have multiple aliases, where an alias corresponds to an identity from a specific auth method. By mapping Sarah's LDAP identity (e.g., her LDAP username) and GitHub identity (e.g., her GitHub username) as aliases to a single entity, Vault associates both identities with one set of policies. The documentation states: "Vault clients can be mapped as entities and their corresponding accounts with authentication providers can be mapped as aliases."
* Why This Works: Assigning policies to the entity ensures that Sarah's permissions remainconsistent regardless of whether she logs in via LDAP or GitHub. This centralizes policy management and eliminates discrepancies.
* Incorrect Options:
* B. External Group Approach: Creating an external group and adding LDAP and GitHub providers as members does not inherently synchronize permissions for a single user like Sarah.
External groups are better suited for mapping group memberships from external systems to Vault policies, not individual identity unification.
* C. Separate Policies: Managing separate policies per auth method is error-prone and inefficient.
Manual synchronization risks inconsistencies, undermining security and manageability.
* D. Trust Relationship: Vault does not support configuring trust relationships between auth methods like LDAP and GitHub to sync accounts. This is a misunderstanding of Vault's architecture.
This entity-based approach leverages Vault's identity system to unify Sarah's access, simplifying administration and ensuring consistency.

NEW QUESTION # 280
From the unseal options listed below, select the options you can use if you're deploying Vault on-premises (select four).

A. AWS KMS
B. Key shards
C. Transit
D. Certificates
E. HSM PKCS11

Answer: A,B,C,E

Explanation:
Comprehensive and Detailed in Depth Explanation:
Vault requires unsealing to access encrypted data, and on-premises deployments support various unseal mechanisms. Let's assess:
* A: CertificatesCertificates secure communication (e.g., TLS), not unsealing. Vault's seal/unseal process uses cryptographic keys, not certificates. Incorrect.
* B: TransitThe Transit secrets engine can auto-unseal Vault by managing encryption keys internally.
Ideal for on-premises setups avoiding external services. Correct.
* C: AWS KMSAWS KMS can auto-unseal Vault if the on-premises cluster has internet access to AWS APIs. Common in hybrid setups. Correct.
* D: HSM PKCS11Hardware Security Modules (HSM) with PKCS11 support secure key storage and auto-unsealing on-premises. Correct.
* E: Key shardsShamir's Secret Sharing splits the master key into shards, the default manual unseal methodfor all Vault clusters. Correct.
Overall Explanation from Vault Docs:
"Vault supports multiple seal types... Key shards (Shamir) is the default... Auto-unseal options like Transit, AWS KMS, and HSM (PKCS11) are viable for on-premises if configured with access to required services." Certificates are not an unseal mechanism.

NEW QUESTION # 281
Which Vault secret engine may be used to build your own internal certificate authority?

A. PKI
B. Generic
C. PostgreSQL
D. Transit

Answer: A

Explanation:
The Vault secret engine that can be used to build your own internal certificate authority is the PKI secret engine. The PKI secret engine generates dynamic X.509 certificates on-demand, without requiring manual processes of generating private keys and CSRs, submitting to a CA, and waiting for verification and signing.
The PKI secret engine can act as a root CA or an intermediate CA, and can issue certificates for various purposes, such as TLS, code signing, email encryption, etc. The PKI secret engine can also manage the certificate lifecycle, such as rotation, revocation, renewal, and CRL generation. The PKI secret engine can also integrate with external CAs, such as Venafi or Entrust, to delegate the certificate issuance and management.

NEW QUESTION # 282
There are a few ways in Vault that can be used to obtain a root token. Select the valid methods from the answers below. (Select three)

A. Generating a root token using a quorum of recovery keys when using Vault auto unseal
B. Initializing Vault when first creating the cluster by using vault operator init
C. Running the command vault token create when using a valid root token
D. Using a batch DR operation token to create a new root token in the event of an emergency

Answer: A,B,C

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Root tokens are restricted in creation. The Vault documentation states:
"Root tokens are tokens that have the root policy attached to them. In fact, there are only three ways to create root tokens:
* The initial root token generated at vault operator init -- this token has no expiration
* By using another root token; a root token with an expiration cannot create a root token that never expires
* By using vault operator generate-root with the permission of a quorum of unseal/recovery key holders"
-Vault Concepts: Tokens
* A,B,D: Correct per the above.
* C: Incorrect; DR tokens are for replication, not root creation:
"DR operation tokens are typically used for disaster recovery operations and may not be directly related to generating a root token in Vault."
-Vault Replication
