NEW QUESTION # 156
Where does the Vault Agent store its cache?
Answer: A
Explanation:
The Vault Agent stores its cache in memory, which means that it does not persist the cached tokens and secrets to disk or any other storage backend. This makes the cache more secure and performant, as it avoids exposing the sensitive data to potential attackers or unauthorized access. However, this also means that the cache is volatile and will be lost if the agent process is terminated or restarted. To mitigate this, the agent can optionally use a persistent cache file to restore the tokens and leases from a previous agent process. The persistent cache file is encrypted using a key derived from the agent's auto-auth token and a nonce, and it is stored in a user-specified location on disk.

NEW QUESTION # 157
Before the following command can be run to encrypt data, what (three) commands must be run to enable and configure the transit secrets engine in Vault? (Select three) text CollapseWrapCopy
$ vault write transit/encrypt/vendor \
plaintext="aGFzaGljb3JwIGNlcnRpZmllZA=="
Answer: B,D,E
Explanation:
Comprehensive and Detailed in Depth Explanation:
To encrypt data using the Transit secrets engine, it must be enabled and configured. The HashiCorp Vault documentation states: "Enable the Transit secrets engine at the default path of 'transit' using the command vault secrets enable transit. Create an encryption key called 'vendor' using the command vault write -f transit
/keys/vendor. Encode the string using base-64 encoding by using the command base64 <<< 'hashicorp certified'." These steps are prerequisites for the given vault write transit/encrypt/vendor command:
* A (base64 <<< "hashicorp certified"): The docs note, "All plaintext data must be base64-encoded.
The reason for this requirement is that Vault does not require that the plaintext is 'text'. It could be a binary file such as a PDF or image. The easiest safe transport mechanism for this data as part of a JSON payload is to base64-encode it." The provided plaintext aGFzaGljb3JwIGNlcnRpZmllZA== is the base64 encoding of "hashicorp certified."
* D (vault secrets enable transit): "Before you can use the transit secrets engine, it must be enabled with vault secrets enable transit at the default path 'transit/'."
* E (vault write -f transit/keys/vendor): "An encryption key must be created before encryption can occur. Use vault write -f transit/keys/vendor to generate a key named 'vendor'." Bis the target command, not a prerequisite.C (vault secrets list)lists engines but doesn't configure Transit.
Thus, A, D, and E are correct.

NEW QUESTION # 158
True or False? Once the lease for a dynamic secret has expired, Vault revokes the credentials on the backend platform for which they were created (i.e., database, AWS, Kubernetes).
Answer: B
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Dynamic secrets are managed actively:
* A. True: "Once the lease for a dynamic secret has expired, Vault automatically revokes the credentials on the backend platform for which they were created." This cleanup reduces technical debt.
* Incorrect Option:
* B. False: Incorrect; revocation is automatic.
"When a lease expires, Vault does indeed revoke the credentials on the platform." Reference:https://developer.hashicorp.com/vault/docs/concepts/lease
NEW QUESTION # 159
Suzy is a Vault user that needs to create and replace values at the path secrets/automation/apps/chef. Does the following policy permit her the permissions to do so?
text
CollapseWrapCopy
path " secrets/automation/apps/chef " {
capabilities = [ " create " , " read " , " list " ]
}
Answer: A
Explanation:
Comprehensive and Detailed In-Depth Explanation:
The policy grants specific capabilities, but not all required for Suzy's needs:
* A. No, Denied Actions : The policy allows " create " , " read " , " list " at secrets/automation/apps/chef.
" Create " permits adding new key-value pairs, but " replace " (updating existing values) requires the " update " capability, which is missing. " If Suzy needs to create AND replace values (update), she needs both create and update capabilities. "
* Incorrect Option :
* B. Yes : Incorrect, as " update " is omitted. " Does not include the update capability, which is required for replacing values. " Without " update " , Suzy can create but not replace values, limiting her ability.

NEW QUESTION # 160
Security requirements demand that no secrets appear in the shell history. Which command does not meet this requirement?
Answer: A
Explanation:
The command that does not meet the security requirement of not having secrets appear in the shell history is B: vault kv put secret/password value-itsasecret. This command would store the secret value "itsasecret" in the key/value secrets engine at the path secret/password, but it would also expose the secret value in the shell history, which could be accessed by other users or malicious actors. This is not a secure way of storing secrets in Vault.
The other commands are more secure ways of storing secrets in Vault without revealing them in the shell history. A. generate-password | vault kv put secret/password value would use a pipe to pass the output of the generate-password command, which could be a script or a tool that generates a random password, to the vault kv put command, which would store the password in the key/value secrets engine at the path secret/password.
The password would not be visible in the shell history, only the commands. C. vault kv put secret/password value=@data.txt would use the @ syntax to read the secret value from a file named data.txt, which could be encrypted or protected by file permissions, and store it in the key/value secrets engine at the path secret
/password. The file name would be visible in the shell history, but not the secret value. D. vault kv put secret
/password value-SSECRET_VALUE would use the -S syntax to read the secret value from the environment variable SECRET_VALUE, which could be set and unset in the shell session, and store it in the key/value secrets engine at the path secret/password. The environment variable name would be visible in the shell history, but not the secret value.
