NEW QUESTION # 120
Which of the following vault lease operations uses a lease _ id as an argument? Choose two correct answers.
Answer: C,D
Explanation:
The vault lease operations that use a lease_id as an argument are renew and revoke. The renew operation allows a client to extend the validity of a lease associated with a secret or a token. The revoke operation allows a client to terminate a lease immediately and invalidate the secret or the token. Both operations require a lease_id as an argument to identify the lease to be renewed or revoked. The lease_id can be obtained from the response of reading a secret or creating a token, or from the vault lease list command. The other operations, revoke-prefix, create, and describe, do not use a lease_id as an argument. The revoke-prefix operation allows a client to revoke all secrets or tokens generated under a given prefix. The create operation allows a client to create a new lease for a secret. The describe operation allows a client to view information about a lease, such as its TTL, policies, and metadata.

NEW QUESTION # 121
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?
Answer: B
Explanation:
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.

NEW QUESTION # 122
What is a benefit of response wrapping?
Answer: B
Explanation:
Response wrapping is a feature that allows Vault to take the response it would have sent to a client and instead insert it into the cubbyhole of a single-use token, returning that token instead. The client can then unwrap the token and retrieve the original response. Response wrapping has several benefits, such as providing cover, malfeasance detection, and lifetime limitation for the secret data. One of the benefits is to ensure that only a single party can ever unwrap the token and see what's inside, as the token can be used only once and cannot be unwrapped by anyone else, even the root user or the creator of the token. This provides a way to securely distribute secrets to the intended recipients and detect any tampering or interception along the way 5 .
The other options are not benefits of response wrapping:
* Log every use of a secret: Response wrapping does not log every use of a secret, as the secret is not directly exposed to the client or the network. However, Vault does log the creation and deletion of the response-wrapping token, and the client can use the audit device to log the unwrapping operation 6 .
* Load balance secret generation across a Vault cluster: Response wrapping does not load balance secret generation across a Vault cluster, as the secret is generated by the Vault server that receives the request and the response-wrapping token is bound to that server. However, Vault does support high availability and replication modes that can distribute the load and improve the performance of the cluster 7 .
* Provide error recovery to a secret so it is not corrupted in transit: Response wrapping does not provide error recovery to a secret so it is not corrupted in transit, as the secret is encrypted and stored in the cubbyhole of the token and cannot be modified or corrupted by anyone. However, if the token is lost or expired, the secret cannot be recovered either, so the client should have a backup or retry mechanism to handle such cases.: 5 (https://developer.hashicorp.com/vault/docs/concepts/response-wrapping), 6 (https://developer.hashicorp.

NEW QUESTION # 123
After encrypting data using the Transit secrets engine, you've received the following output. Which of the following is true based on the output displayed below?
Key: ciphertext Value: vault:v2:
45f9zW6cglbrzCjI0yCyC6DBYtSBSxnMgUn9B5aHcGEit71xefPEmmjMbrk3
Answer: C
Explanation:
Comprehensive and Detailed in Depth Explanation:
* A:v2 shows the key was rotated once. Correct.
* B:Transit doesn't store data. Incorrect.
* C:v2 is the key version, not data version. Incorrect.
* D:No transit v2 option exists. Incorrect.
Overall Explanation from Vault Docs:
"Ciphertext is prepended with the key version (e.g., v2)... Indicates rotation." Reference:https://developer.hashicorp.com/vault/tutorials/encryption-as-a-service/eaas-transit#rotate-the- encryption-key
NEW QUESTION # 124
What is the difference between the TTL and the Max TTL (select two)?
Answer: A,B
Explanation:
Comprehensive and Detailed in Depth Explanation:
Vault tokens have two key time attributes:TTL(Time-To-Live) andMax TTL(Maximum Time-To-Live), governing their lifecycle. Let's dissect each option:
* Option A: The TTL defines when the token will expire and be revokedThe TTL is the current lifespan of a token before it expires. For example, a token with a TTL of 24h (vault token create - ttl=24h) expires 24 hours from creation unless renewed. Upon expiry, Vault revokes it automatically.
This is a fundamental property of TTL, making this statement accurate. Correct.Vault Docs Insight:
"The TTL defines when the token will expire... if it reaches its TTL, it will be revoked by Vault." (Core definition.)
* Option B: The TTL defines when another token will be generatedTTL governs expiration, not token generation. New tokens are created explicitly (e.g., vault token create) or via auth methods, not automatically by TTL. This misunderstands TTL's role-it's about expiry, not regeneration. Incorrect.
Vault Docs Insight:"TTL is the duration until expiration... New tokens are not generated by TTL." (No generation link.)
* Option C: The Max TTL defines the timeframe for which a token cannot be usedThis is backwards. Max TTL sets the upper limit a token can exist through renewals, not a period of inactivity or unusability. A token with a Max TTL of 72h can be renewed up to 72 hours from creation, after which it's revoked. This option inverts the concept. Incorrect.Vault Docs Insight:"Max TTL defines the maximum timeframe for which the token can be renewed... not a usage restriction." (Opposite meaning.)
* Option D: The Max TTL defines the maximum timeframe for which a token can be renewedMax TTL caps the total lifespan of a token, including renewals. For example, a token with TTL=24h and Max TTL=72h (vault token create -ttl=24h -explicit-max-ttl=72h) can be renewed twice (24h + 24h +
24h = 72h) before hitting the limit. Beyond 72h, renewal fails, and it expires. This is the precise definition of Max TTL. Correct.Vault Docs Insight:"The Max TTL defines the maximum timeframe for which the token can be renewed... Once reached, it cannot be renewed further." (Exact match.) Detailed Mechanics:
TTL is dynamic, decreasing as time passes (e.g., vault token lookup shows ttl: 23h59m50s after 10 seconds).
Renewal (vault token renew) resets TTL to its original value (e.g., 24h), but only up to Max TTL from creation. System defaults (768h/32 days) apply unless overridden. Periodic tokens (-period=24h) renew indefinitely within their period, ignoring Max TTL unless explicitly set.
Real-World Example:
Create: vault token create -ttl=1h -explicit-max-ttl=3h. After 1h, TTL=0, renewable. Renew at 2h total, TTL=1h again. At 3h total, Max TTL hits-revoked. Contrast with TTL-only: vault token create -ttl=1h, renewable up to system Max TTL (768h).
Overall Explanation from Vault Docs:
"The TTL defines when the token will expire... If it reaches its TTL, it will be immediately revoked by Vault.
The Max TTL defines the maximum timeframe for which the token can be renewed... Once the Max TTL is reached, the token cannot be renewed any longer and will be revoked." These attributes ensure controlled token lifecycles.
