Pass the HashiCorp Security Automation Certification HCVA0-003 Questions and answers with Dumpstech

Comprehensive and Detailed in Depth Explanation:

A: Soft-deletes data, not metadata. Incorrect.

B: Destroys a version, not the path. Incorrect.

C: Deletes all metadata and versions, removing the path. Correct.

D: Invalid syntax. Incorrect.

Overall Explanation from Vault Docs:

“kv metadata delete deletes all versions and metadata for the key, permanently removing it.”

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.”

Comprehensive and Detailed in Depth Explanation:

cubbyhole is default; kv and transit are user-enabled. Total: 3.

Overall Explanation from Vault Docs:

“cubbyhole is enabled by default… User-enabled engines add to this.”

Comprehensive and Detailed in Depth Explanation:

This question requires identifying a policy that permits reading the secret at secrets/applications/app01/api_key. Vault policies use paths and capabilities to control access. Let’s evaluate:

A: path " secrets/applications/ " { capabilities = [ " read " ] allowed_parameters = { " certificate " = [] } } This policy allows reading at secrets/applications/, but not deeper paths like secrets/applications/app01/api_key. The allowed_parameters restriction is irrelevant for reading secrets. Incorrect.

B: path " secrets/* " { capabilities = [ " list " ] } The list capability allows listing secrets under secrets/, but not reading their contents. Reading requires the read capability. Incorrect.

C: path " secrets/applications/+/api_* " { capabilities = [ " read " ] } The + wildcard matches one segment (e.g., app01), and api_* matches api_key. This policy grants read access to secrets/applications/app01/api_key. Correct.

D: path " secrets/applications/app01/api_key/* " { capabilities = [ " update " , " list " , " read " ] } This policy applies to subpaths under api_key/, not the exact path api_key. It includes read, but the path mismatch makes it incorrect for this specific secret.

Overall Explanation from Vault Docs:

“Wildcards (*, +) allow flexible path matching… read capability is required to retrieve secret data.” Option C uses globbing to precisely target the required path.

Comprehensive and Detailed in Depth Explanation:

Enabling a secrets engine in Vault follows a specific syntax:

A: Incorrect syntax; jumbled order.

B: Correct: vault secrets enable < type > enables the AWS engine at aws/. Correct.

C: Incorrect word order.

D: Incorrect syntax.

Overall Explanation from Vault Docs:

“The command vault secrets enable < type > enables a secrets engine at its default path (e.g., aws/ for AWS).”

Comprehensive and Detailed in Depth Explanation:

Token renewal extends a token’s TTL. Let’s evaluate:

A: TTL - Defines expiration time, not used for renewal. Incorrect.

B: Token ID - The token’s unique identifier; can be specified to renew it (e.g., vault token renew < token-id > ). Correct.

C: Identity policy - Relates to access control, not renewal. Incorrect.

D: Token accessor - A unique identifier for operations like renewal without exposing the token (e.g., vault token renew -accessor < accessor > ). Correct.

Overall Explanation from Vault Docs:

“Tokens can be renewed with vault token renew using either the token ID or accessor… TTL is not an attribute for renewal.”

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.”
