NEW QUESTION # 256
You have a long-running app that cannot handle a regeneration of a token or secret. What type of token should be created for this application in order to authenticate and interact with Vault?

A. Orphan Token
B. Batch Token
C. Service Token with Use Limit
D. Periodic Service Token

Answer: D

Explanation:
Comprehensive and Detailed in Depth Explanation:
For a long-running application that cannot handle token or secret regeneration, thePeriodic Service Tokenis the most suitable choice. According to HashiCorp Vault documentation, periodic service tokens are renewable tokens that do not have a maximum Time-to-Live (TTL), meaning they can be renewed indefinitely by the client without requiring manual intervention or regeneration. This is ideal for applications needing continuous access to Vault over an extended period. The documentation states: "Periodic tokens have a TTL, but no max TTL. Periodic tokens may live for an infinite amount of time, so long as they are renewed within their TTL." This feature ensures uninterrupted operation for long-running processes, aligning perfectly with the scenario described.
In contrast, aService Token with Use Limithas a finite number of uses before expiration, making it unsuitable for continuous access without regeneration. ABatch Tokenis designed for short-lived, one-time operations or batch processes, not persistent access, as it lacks renewability and has a fixed TTL. AnOrphan Token, while not tied to a parent token, does not inherently address the regeneration issue and is less secure for long-term use due to its lack of association with policies or identity. Thus, the periodic service token stands out as the best fit.

NEW QUESTION # 257
What could you do with the feature found in the screenshot below (select two)?

A. Use response-wrapping to protect data
B. Encrypt the Vault master key that is stored in memory
C. Encrypt sensitive data to send to a colleague over email
D. Using a short TTL, you could encrypt data in order to place only the encrypted data in Vault

Answer: A,C

Explanation:
Comprehensive and Detailed in Depth Explanation:
The screenshot highlights Vault'sresponse wrappingfeature, 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 VaultThis 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 memoryThe 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 emailThis 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 dataThis 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 cubbyholesecrets 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'sencryption 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.

NEW QUESTION # 258
There are a few ways in Vault that can be used to obtain a root token. Select the valid methods from the answers below. (Select three)

A. Generating a root token using a quorum of recovery keys when using Vault auto unseal
B. Running the command vault token create when using a valid root token
C. Initializing Vault when first creating the cluster by using vault operator init
D. Using a batch DR operation token to create a new root token in the event of an emergency

Answer: A,B,C

Explanation:
Comprehensive and Detailed In-Depth Explanation:
Root tokens are restricted in creation. The Vault documentation states:
"Root tokens are tokens that have the root policy attached to them. In fact, there are only three ways to create root tokens:
* The initial root token generated at vault operator init -- this token has no expiration
* By using another root token; a root token with an expiration cannot create a root token that never expires
* By using vault operator generate-root with the permission of a quorum of unseal/recovery key holders"
-Vault Concepts: Tokens
* A,B,D: Correct per the above.
* C: Incorrect; DR tokens are for replication, not root creation:
"DR operation tokens are typically used for disaster recovery operations and may not be directly related to generating a root token in Vault."
-Vault Replication

NEW QUESTION # 259
The vault lease renew command increments the lease time from:

A. The current time
B. The end of the lease

Answer: A

Explanation:
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:
