HashiCorp Certified: Vault Associate (003)Exam Sample Questions (Q68-Q73):

NEW QUESTION # 68
Which of these is not a benefit of dynamic secrets?

  • A. Ensures that administrators can see every password used
  • B. Replaces cumbersome password rotation tools and practices
  • C. Supports systems which do not natively provide a method of expiring credentials
  • D. Minimizes damage of credentials leaking

Answer: A

Explanation:
Dynamic secrets are generated on-demand by Vault and have a limited time-to-live (TTL). They do not ensure that administrators can see every password used, as they are often encrypted and ephemeral.The benefits of dynamic secrets are:
* They support systems that do not natively provide a method of expiring credentials, such as databases, cloud providers, SSH, etc. Vault can revoke the credentials when they are no longer needed or when the lease expires.
* They minimize the damage of credentials leaking, as they are short-lived and can be easily rotated or revoked. If a credential is compromised, the attacker has a limited window of opportunity to use it before it becomes invalid.
* They replace cumbersome password rotation tools and practices, as Vault can handle the generation and revocation of credentials automatically and securely. This reduces the operational overhead and complexity of managing secrets.

NEW QUESTION # 69
When looking at Vault token details, which key helps you find the paths the token is able to access?

  • A. Policies
  • B. Meta
  • C. Accessor
  • D. Path

Answer: A

Explanation:
When looking at Vault token details, the policies key helps you find the paths the token is able to access.
Policies are a declarative way to grant or forbid access to certain paths and operations in Vault. Policies are written in HCL or JSON and are attached to tokens by name. Policies are deny by default, so an empty policy grants no permission in the system. A token can have one or more policies associated with it, and the effective policy is the union of all the individual policies. You can view the token details by using the vault token lookup command or the auth/token/lookup API endpoint. The output will show the policies key with a list of policy names that are attached to the token. You can also view the contents of a policy by using the vault policy read command or the sys/policy API endpoint. The output will show the rules key with the HCL or JSON representation of the policy. The rules will specify the paths and the capabilities (such as create, read, update, delete, list, etc.) that the policy allows or denies. References: https://developer.hashicorp.com/vault

NEW QUESTION # 70
What are the primary benefits of running Vault in a production deployment over dev server mode (select two)?

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

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 # 71
When unsealing Vault, each Shamir unseal key should be entered:

  • A. Sequentially from one system that all of the administrators are in front of
  • B. At the command line in one single command
  • C. By different administrators each connecting from different computers
  • D. While encrypted with each administrators PGP key

Answer: C

Explanation:
When unsealing Vault, each Shamir unseal key should be entered by different administrators each connecting from different computers. This is because the Shamir unseal keys are split into shares that are distributed to trusted operators, and no single operator should have access to more than one share. This way, the unseal process requires the cooperation of a quorum of key holders, and enhances the security and availability of Vault. The unseal keys can be entered via multiple mechanisms from multiple client machines, and the process is stateful. The order of the keys does not matter, as long as the threshold number of keys is reached.
The unseal keys should not be entered at the command line in one single command, as this would expose them to the history and compromise the security. The unseal keys should not be encrypted with each administrator's PGP key, as this would prevent Vault from decrypting them and reconstructing the master key.

NEW QUESTION # 72
Below is a list of parent and child tokens and their associated TTL. Which token(s) will be revoked first?

  • A. ####hvs.3IrlhEvcerEGbae11YQf9FvI - TTL: 3 hours
  • B. ####hvs.hOpweMVFvqfvoVnNgvZq8jLS - TTL: 5 hours (child of D)
  • C. ####hvs.Jw9LMpu7oCQgxiKbjfyzyg75 - TTL: 4 hours (child of B)
  • D. ####hvs.FNiIFU14RUxxUYAl4ErLfPVR - TTL: 6 hours
  • E. ####hvs.y4fUERqCtUV0xsQjWLJar5qX - TTL: 4 hours

Answer: A

Explanation:
Comprehensive and Detailed in Depth Explanation:
Vault tokens have a Time-To-Live (TTL) that determines their expiration time, after which they are revoked.
Parent-child relationships mean that revoking a parent token also revokes its children, regardless of their TTLs. Let's analyze:
* A: TTL 4 hours- Expires after 4 hours, no children listed.
* B: TTL 6 hours- Expires after 6 hours, parent to C.
* C: TTL 4 hours (child of B)- Expires after 4 hours or if B is revoked earlier.
* D: TTL 3 hours- Expires after 3 hours, parent to E.
* E: TTL 5 hours (child of D)- Expires after 5 hours or if D is revoked earlier.
Analysis:
* Shortest TTL is D (3 hours), so it expires first unless a parent above it (none listed) is revoked sooner.
* E (5 hours) is a child of D. If D is revoked at 3 hours, E is also revoked, despite its longer TTL.
* A and C (4 hours) expire after D.
* B (6 hours) expires last among parents.
The question asks which token(s) are revoked first based on TTL alone, not manual revocation. D has the shortest TTL (3 hours) and will be revoked first. E's revocation depends on D, but the question focuses on initial expiration. Thus, only D is revoked first based on its TTL.
Overall Explanation from Vault Docs:
Tokens form a hierarchy where child tokens inherit revocation from their parents. "When a parent token is revoked, all of its child tokens-and all of their leases-are revoked as well." TTL dictates automatic expiration unless overridden by manual revocation or parent revocation. Here, D's 3-hour TTL is the shortest, making it the first to expire naturally.
