HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q109-Q114):

NEW QUESTION # 109
You are using Vault's Transit secrets engine to encrypt your data. You want to reduce the amount of content encrypted with a single key in case the key gets compromised. How would you do this?

A. Periodically rotate the encryption key
B. Periodically re-key the Vault's unseal keys
C. Use 4096-bit RSA key to encrypt the data
D. Upgrade to Vault Enterprise and integrate with HSM

Answer: A

Explanation:
The Transit secrets engine supports the rotation of encryption keys, which allows you to change the key that is used to encrypt new data without affecting the ability to decrypt data that was already encrypted. This reduces the amount of content encrypted with a single key in case the key gets compromised, and also helps you comply with the NIST guidelines for key rotation. You can rotate the encryption key manually by invoking the /transit/keys/<name>/rotate endpoint, or you can configure the key to automatically rotate based on a time interval or a number of encryption operations. When you rotate a key, Vault generates a new key version and increments the key's latest_version metadata. The new key version becomes the encryption key used for encrypting any new data. The previous key versions are still available for decrypting the existing data, unless you specify a minimum decryption version to archive the old key versions. You can also delete or disable old key versions if you want to revoke access to the data encrypted with those versions. References:

NEW QUESTION # 110
Which scenario most strongly indicates a need to run a self-hosted Vault cluster instead of using HCP Vault Dedicated?

A. You want to offload all operational tasks and rely on HashiCorp to manage patching, upgrades, and infrastructure
B. Your organization doesn't require any custom security policies or intricate network topologies
C. You prefer a fully managed environment that is readily scalable with minimal configuration overhead
D. You must maintain specific compliance or custom integration requirements that demand full control over the Vault environment, including infrastructure provisioning and plugin development

Answer: D

Explanation:
Comprehensive and Detailed in Depth Explanation:
HCP Vault Dedicated is a managed service, while self-hosted Vault (Community or Enterprise) requires user management. Let's evaluate:
* A:Simple needs favor HCP Vault's managed simplicity. Incorrect.
* B:Offloading tasks aligns with HCP Vault, not self-hosted. Incorrect.
* C:Managed scalability suits HCP Vault. Incorrect.
* D:Compliance, custom integrations, and plugin development need full control, only possible with self- hosted Vault. Correct.
Detailed Mechanics:
Self-hosted Vault allows custom plugins, FIPS 140-2 compliance, and specific network configs (e.g., air- gapped setups), unavailable in HCP Vault Dedicated due to its standardized, managed nature.
Overall Explanation from Vault Docs:
"Self-managed Vault supports custom requirements... HCP Vault Dedicated offloads operations but limits control." Reference:https://developer.hashicorp.com/vault/tutorials/get-started/available-editions

NEW QUESTION # 111
Which of the following are valid types of tokens available in Vault? (Select five)

A. Batch token
B. Service token
C. Root token
D. Orphan service token
E. Periodic service token
F. Primary token

Answer: A,B,C,D,E

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Vault supports several token types, each with distinct characteristics:
* B. Batch token: "Batch tokens are encrypted binary large objects (blobs) that carry just enough information for authentication." They are lightweight and non-renewable.
* C. Orphan service token: "Orphan tokens are not children of their parent; therefore, do not expire when their parent does." A valid subtype of service tokens.
* D. Service token: "Service token is the general token that most people talk about when referring to a token in Vault." The standard token type.
* E. Root token: "Root tokens are the most powerful tokens in Vault and have full control." Created during initialization.
* F. Periodic service token: "Periodic service tokens have a TTL, but no max TTL," renewing automatically for long-running tasks.
* Incorrect Option:
* A. Primary token: "Not a valid token type in Vault." No such term exists in Vault's documentation.
These token types cater to various use cases, from ephemeral to privileged access.

NEW QUESTION # 112
What are the primary benefits of running Vault in a production deployment over dev server mode (select two)?

A. Faster deployment
B. Persistent storage
C. Encryption via TLS
D. Ability to enable auth methods

Answer: B,C

Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:Dev mode is faster to deploy; incorrect.
* B:Production uses persistent storage vs. dev's in-memory. Correct.
* C:Auth methods work in both modes. Incorrect.
* D:Production enables TLS; dev uses plaintext. Correct.
Overall Explanation from Vault Docs:
"Dev server mode stores data in memory... Production mode supports persistent storage and TLS encryption." Reference:https://developer.hashicorp.com/vault/docs/concepts/dev-server

NEW QUESTION # 113
Which of the following statements are true about Vault policies? Choose two correct answers.

A. Policies deny by default (empty policy grants no permission)
B. The default policy can not be modified
C. You must use YAML to define policies
D. Vault must be restarted in order for a policy change to take an effect
E. Policies provide a declarative way to grant or forbid access to certain paths and operations in Vault

Answer: A,E

Explanation:
Vault policies are written in HCL or JSON format and are attached to tokens or roles by name. Policies define the permissions and restrictions for accessing and performing operations on certain paths and secrets in Vault. Policies are deny by default, which means that an empty policy grants no permission in the system, and any request that is not explicitly allowed by a policy is implicitly denied1. Some of the features and benefits of Vault policies are:
* Policies are path-based, which means that they match the request path to a set of rules that specify the allowed or denied capabilities, such as create, read, update, delete, list, sudo, etc2.
* Policies are additive, which means that if a token or a role has multiple policies attached, the effective policy is the union of all the individual policies. The most permissive capability is granted if there is a conflict3.
* Policies can use glob patterns, such as * and +, to match multiple paths or segments with a single rule. For example, path "secret/*" matches any path starting with secret/, and path "secret/+/config" matches any path with two segments after secret/ and ending with config4.
* Policies can use templating to interpolate certain values into the rules, such as identity information, time, randomness, etc. For example, path "secret/{{identity.entity.id}}/*" matches any path starting with secret/ followed by the entity ID of the requester5.
* Policies can be managed by using the vault policy commands or the sys/policy API endpoints. You can write, read, list, and delete policies by using these interfaces6.
The default policy is a built-in policy that is attached to all tokens by default and cannot be deleted. However, the default policy can be modified by using the vault policy write command or the sys/policy API endpoint. The default policy provides common permissions for tokens, such as renewing themselves, looking up their own information, creating and managing response-wrapping tokens, etc7.
You do not have to use YAML to define policies, as Vault supports both HCL and JSON formats. HCL is a human-friendly configuration language that is also JSON compatible, which means that JSON can be used as a valid input for policies as well8.
Vault does not need to be restarted in order for a policy change to take effect, as policies are stored and evaluated in memory. Any change to a policy is immediately reflected in the system, and any token or role that has that policy attached will be affected by the change.: 1(https://developer.hashicorp.com/vault/docs/concepts/policies), 2(https://developer.hashicorp.com/vault
