* Incorrect Options:
* A: Incomplete.
* C, D: Expose password in history.

질문 # 146
To secure your applications, your organization uses certificates generated by a public CA. However, this strategy has proven expensive and you have to revoke certificates even though they have additional time left.
What Vault plugin can be used to quickly generate X.509 certificates to secure your internal applications?

정답：D

설명：
Comprehensive and Detailed In-Depth Explanation:
The PKI secrets engine in Vault generates dynamic X.509 certificates, acting as a certificate authority (CA) or intermediate CA. It allows quick, cost-effective certificate creation for internal applications, with configurable TTLs and revocation capabilities, avoiding reliance on expensive public CAs. For example, vault write pki
/issue/ < role > generates a certificate instantly. The Identity engine (A) manages identities, not certificates.
The SSH engine (C) handles SSH credentials, not X.509. The Transit engine (D) is for encryption, not certificate generation. The PKI docs highlight its suitability for this use case.

질문 # 147
You have multiple Vault clusters in your environment, one for test and one for production. You have the CLI installed on your local machine and need to target the production cluster to make configuration changes. What environment variable can you set to target the production cluster?

정답：C

설명：
Comprehensive and Detailed In-Depth Explanation:
The VAULT_ADDR variable specifies the target Vault server. The Vault documentation states:
"VAULT_ADDR is the environment variable that is used to specify the address of the Vault server expressed as a URL and port, for example: https://vault.bryankrausen.com:8200/. You can easily modify the value of the environment variable whenever you want to target a different Vault node/cluster."
-Vault Environment Variables
* C: Correct. Sets the production cluster address:
"Setting the VAULT_ADDR environment variable allows you to specify the address of the Vault server you want to target."
-Vault Environment Variables
* A,B,D: Incorrect; unrelated to CLI targeting.

질문 # 148
Your Azure Subscription ID is stored in Vault and you need to retrieve it via Vault API for an automated job.
The Subscription ID is stored at secret/cloud/azure/subscription. The secret is stored on a KV Version 2 secrets engine. What curl command below would successfully retrieve the latest version of the secret?

정답：A

설명：
Comprehensive and Detailed In-Depth Explanation:
For a KV v2 secrets engine, the API path to retrieve a secret's data is /v1/<mount>/data/<path>. Here, the mount is secret/, and the path is cloud/azure/subscription, making the correct endpoint /v1/secret/data/cloud
/azure/subscription. Authentication requires the X-Vault-Token header with a valid token. Option C matches this exactly and retrieves the latest version by default, as per KV v2 API behavior. Option A lacks the token.
Option B omits the /data/ segment, invalid for KV v2. Option D adds /latest, which isn't a valid KV v2 endpoint. The KV v2 API docs confirm this structure.

Vault API Overview


질문 # 149
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?

정답：B

설명：
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:
