質問 # 199
When Vault is sealed, which are the only two operations available to a Vault administrator? (Select two)
正解：E、F
解説：
Comprehensive and Detailed in Depth Explanation:
When Vault is sealed, its functionality is severely restricted to protect encrypted data. The HashiCorp Vault documentation states: "While Vault is sealed, the only two options available are viewing the vault status (vault status) and unsealing Vault (vault operator unseal). All the other actions require Vault to be unsealed and the user to be authenticated." This limitation ensures that no operations can access or modify data until the Vault is unsealed, enhancing security.
The documentation under "Shamir Seals" further elaborates: "When Vault is sealed, it knows where its encrypted data is stored but cannot decrypt it because the master key is not in memory. The only available operations are checking the seal status and initiating the unseal process." Thus:
* A (View the status of Vault): The vault status command works when sealed, providing details like seal state.
* E (Unseal Vault): The vault operator unseal command allows administrators to begin unsealing.
Options likeconfigure policies (B),view data in the key/value store (C),rotate the encryption key (D), and author security policies (F)require an unsealed Vault and authentication, making A and E the correct selections.

質問 # 201
What could you do with the feature found in the screenshot below (select two)?
正解：B、D
解説：
Comprehensive and Detailed in Depth Explanation:
The screenshot highlights Vault's response wrapping feature, accessible via the UI's "Wrap" option. This feature wraps a Vault response (e.g., a secret or token) in a single-use token with a configurable TTL, ensuring secure delivery to an intended recipient. Let's evaluate each option against this capability:
* Option A: Using a short TTL, you could encrypt data in order to place only the encrypted data in Vault This misinterprets response wrapping. Wrapping doesn't encrypt data for storage in Vault; it secures a response for transmission outside Vault. Encryption for storage would involve the Transit secrets engine, not wrapping. The TTL in wrapping limits the wrapped token's validity, not the data's encryption lifecycle. This option conflates two unrelated features and is incorrect. Vault Docs Insight:
"Response wrapping does not store data in Vault; it delivers it securely to a recipient." (No direct storage implication.)
* Option B: Encrypt the Vault master key that is stored in memory The master key in Vault is already encrypted at rest (in storage) and decrypted in memory during operation using the unseal process (e.g., Shamir shares or auto-unseal). Response wrapping doesn't interact with the master key- it's a client-facing feature for secret delivery, not an internal encryption mechanism. This is a fundamental misunderstanding of Vault's architecture and wrapping's purpose. Incorrect. Vault Docs Insight: "The master key is managed by the seal mechanism, not client-facing features like wrapping." (See seal/unseal docs.)
* Option C: Encrypt sensitive data to send to a colleague over email This aligns perfectly with response wrapping. You can retrieve a secret (e.g., vault read secret/data/my-secret), wrap it with a short TTL (e.g., 5 minutes), and receive a token (e.g., hvs. < token > ). You email this token to a colleague, who unwraps it with vault unwrap < token > to access the secret. The data is encrypted within the token, secure during transit, and expires after the TTL. This is a textbook use case for wrapping. Correct. Vault Docs Insight: "Response wrapping... can be used to securely send sensitive data to another party, such as over email, with a limited lifetime." (Directly supported use case.)
* Option D: Use response-wrapping to protect data This is the essence of the feature. Wrapping protects data by encapsulating it in a single-use token, accessible only via an unwrap operation. For example, vault write -wrap-ttl=60s secret/data/my-secret returns a wrapped token, protecting the secret until unwrapped. This ensures confidentiality and controlled access, making it a core benefit of the feature. Correct. Vault Docs Insight: "Vault can wrap a response in a single-use token... protecting the data until unwrapped by the recipient." (Core definition.) Detailed Mechanics:
Response wrapping works by taking a Vault API response (e.g., a secret's JSON payload) and storing it in the cubbyhole secrets engine under a newly generated single-use token. The token's TTL (e.g., 60s) limits its validity. The API call POST /v1/sys/wrapping/wrap with a payload (e.g., { " ttl " : " 60s " , " data " : { " key ": " value " }}) returns { " wrap_info " : { " token " : " hvs. < token > " }}. The recipient uses vault unwrap hvs. < token > (or POST /v1/sys/wrapping/unwrap) to retrieve the original data. Once unwrapped, the token is revoked, ensuring one-time use. This leverages Vault's encryption and token system for secure data exchange.
Real-World Example:
You generate an API key in Vault: vault write secret/data/api key=abc123. In the UI, you click "Wrap" with a
5-minute TTL, getting hvs.XYZ. You email hvs.XYZ to a colleague, who runs vault unwrap hvs.XYZ within
5 minutes to get key=abc123. After unwrapping, the token is invalid, and the secret is safe from interception.
Overall Explanation from Vault Docs:
"Vault includes a feature called response wrapping. When requested, Vault can take the response it would have sent to an HTTP client and instead insert it into the cubbyhole of a single-use token, returning that token instead... This is useful for securely delivering sensitive data." The feature excels at protecting data in transit (e.g., email) and enforcing one-time access, not internal key management or storage encryption.

質問 # 202
The vault lease renew command increments the lease time from:
正解：B
解説：
The vault lease renew command increments the lease time from the current time, not the end of the lease. This means that the user can request a specific amount of time they want remaining on the lease, termed the increment. This is not an increment at the end of the current TTL; it is an increment from the current time. For example, vault lease renew -increment=3600 my-lease-id would request that the TTL of the lease be adjusted to 1 hour (3600 seconds) from now. Having the increment be rooted at the current time instead of the end of the lease makes it easy for users to reduce the length of leases if they don't actually need credentials for the full possible lease period, allowing those credentials to expire sooner and resources to be cleaned up earlier.
The requested increment is completely advisory. The backend in charge of the secret can choose to completely ignore it1. References:

質問 # 203
The HTTP POST method was used to invoke the Vault API endpoint /auth/ldap/login/:username.
Which statements describe this operation?
Pick the 2 correct responses below.
正解：B、E
解説：
The LDAP login endpoint is an authentication endpoint, so a Vault token is not required before the login request. The purpose of this operation is to exchange valid LDAP credentials for a Vault client token. The correct request uses HTTP POST against /auth/ldap/login/:username, and the password is provided in the request payload. If authentication succeeds, Vault returns an auth object containing client_token, which is then used for later Vault API requests. The response is normal API output, not something that must be Base64- decrypted. The CLI and UI are only clients of Vault; authentication can also be performed directly through the HTTP API. HashiCorp's LDAP API documentation shows the login path, required password parameter, and sample response containing auth.client_token.
