NEW QUESTION # 247
What is the default TTL for tokens in Vault if one is not specified?
Answer: B
Explanation:
Comprehensive and Detailed In-Depth Explanation:
In HashiCorp Vault, thedefault TTL (Time To Live)for tokens, when not explicitly specified, is768 hours, equivalent to32 days. This applies to both the initial TTL and the maximum TTL unless overridden.
* Default Configuration: The documentation states: "When no specific TTL is provided, a generated token will inherit the default TTL which is 768 hours (32 days)." This long default ensures usability in many scenarios while allowing customization.
* Customization Option: Operators can adjust this using commands like vault write sys/mounts/auth
/token/tune default_lease_ttl=1h max_lease_ttl=24h, but without such tuning, 768 hours applies.
* Incorrect Options:
* A. 24 hours: Too short for Vault's default; it's a common custom setting instead.
* B. 15 minutes: Far too brief and not aligned with Vault's defaults.
* D. 60 minutes: Another common custom value, not the default.
This default balances usability with security, encouraging explicit configuration for shorter-lived tokens when needed.

NEW QUESTION # 248
Which of the following vault lease operations uses a lease _ id as an argument? Choose two correct answers.
Answer: A,E
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 # 249
Your company ' s security policies require that all encryption keys must be rotated at least once per year.
After using the Transit secrets engine for a year, the Vault admin issues the proper command to rotate the key named ecommerce that was used to encrypt your data. What command can be used to easily re-encrypt the original data with the new version of the key?
Answer: A
Explanation:
Comprehensive and Detailed in Depth Explanation:
The Transit secrets engine in Vault manages encryption keys and supports key rotation. After rotating the ecommerce key, existing ciphertext (encrypted with the old key version) must be re-encrypted (rewrapped) with the new key version without exposing plaintext. Let's evaluate:
* A: vault write -f transit/keys/ecommerce/rotate < old data > This command rotates the key, creating a new version, but does not re-encrypt existing data. It's for key management, not data rewrapping.
Incorrect.
* B: vault write -f transit/keys/ecommerce/update < old data > There's no update endpoint in Transit for re-encrypting data. This is invalid and incorrect.
* C: vault write transit/encrypt/ecommerce v1:v2 < old data > The transit/encrypt endpoint encrypts new plaintext, not existing ciphertext. The v1:v2 syntax is invalid. Incorrect.
* D: vault write transit/rewrap/ecommerce ciphertext= < old data > The transit/rewrap endpoint takes existing ciphertext, decrypts it with the old key version, and re-encrypts it with the latest key version (post-rotation). This is the correct command. For example, if < old data > is vault:v1:cZNHVx+..., the output might be vault:v2:kChHZ9w4....
Overall Explanation from Vault Docs:
"Vault's Transit secrets engine supports key rotation... The rewrap endpoint allows ciphertext encrypted with an older key version to be re-encrypted with the latest key version without exposing the plaintext." This operation is secure and efficient, using the keyring internally.

NEW QUESTION # 250
Which of the following token attributes can be used to renew a token in Vault (select two)?
Answer: B,D
Explanation:
Comprehensive and Detailed in Depth Explanation:
Token renewal extends a token's TTL. Let's evaluate:
* A: TTL - Defines expiration time, not used for renewal. Incorrect.
* B: Token ID - The token's unique identifier; can be specified to renew it (e.g., vault token renew < token-id > ). Correct.
* C: Identity policy - Relates to access control, not renewal. Incorrect.
* D: Token accessor - A unique identifier for operations like renewal without exposing the token (e.g., vault token renew -accessor < accessor > ). Correct.
Overall Explanation from Vault Docs:
"Tokens can be renewed with vault token renew using either the token ID or accessor... TTL is not an attribute for renewal." Reference: https://developer.hashicorp.com/vault/docs/commands/token/renew#token-renew
NEW QUESTION # 251
In Vault, there are two main types of tokens, batch and service. Which of the following is true about the renewable capabilities of each?
Answer: B
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Token renewability differs:
* A. Correct: "Batch tokens cannot be renewed by Vault, but service tokens can be renewed up to the Max TTL of the token."
* Incorrect Options:
* B: Service tokens renew without reauth.
* C: Reverses the truth.
* D: Batch tokens are non-renewable.
