NEW QUESTION # 111
A web application uses Vault's transit secrets engine to encrypt data in-transit. If an attacker intercepts the data in transit which of the following statements are true? Choose two correct answers.
Answer: C,D
Explanation:
A web application that uses Vault's transit secrets engine to encrypt data in-transit can benefit from the following security features:
* Even if the attacker was able to access the raw data, they would only have encrypted bits (TLS in transit). This means that the attacker would need to obtain the encryption key from Vault in order to decrypt the data, which is protected by Vault's authentication and authorization mechanisms. The transit secrets engine does not store the data sent to it, so the attacker cannot access the data from Vault either.
* The keys can be rotated and min_decryption_version moved forward to ensure this data cannot be decrypted. This means that the web application can periodically change the encryption key used to encrypt the data, and set a minimum decryption version for the key, which prevents older versions of the key from being used to decrypt the data. This way, even if the attacker somehow obtained an old version of the key, they would not be able to decrypt the data that was encrypted with a newer version of the key.
The other statements are not true, because:
* You cannot rotate the encryption key so that the attacker won't be able to decrypt the data. Rotating the key alone does not prevent the attacker from decrypting the data, as they may still have access to the old version of the key that was used to encrypt the data. You need to also move the min_decryption_version forward to invalidate the old version of the key.
* The Vault administrator would not need to seal the Vault server immediately. Sealing the Vault server would make it inaccessible to both the attacker and the legitimate users, and would require unsealing it with the unseal keys or the recovery keys. Sealing the Vault server is a last resort option in case of a severe compromise or emergency, and is not necessary in this scenario, as the attacker does not have access to the encryption key or the data in Vault.

NEW QUESTION # 112
The Vault encryption key is stored in Vault's backend storage.
Answer: A
Explanation:
The statement is false. The Vault encryption key is not stored in Vault's backend storage, but rather in Vault's memory. The Vault encryption key is the key that is used to encrypt and decrypt the data that is stored in Vault's backend storage, such as secrets, tokens, policies, etc. The Vault encryption key is derived from the master key, which is generated when Vault is initialized. The master key is split into unseal keys using Shamir's secret sharing algorithm, and the unseal keys are distributed to trusted operators. To start Vault, a quorum of unseal keys is required to reconstruct the master key and derive theencryption key. The encryption key is then kept in memory and used to protect the data in Vault's backend storage. The encryption key is never written to disk or exposed via the API.

NEW QUESTION # 113
After a client has authenticated to Vault, what security feature is used to make all subsequent calls?
Answer: E
Explanation:
Comprehensive and Detailed in Depth Explanation:
After authentication, Vault uses tokens for all subsequent calls. The HashiCorp Vault documentation states: " After authenticating, a client is issued a service token which is associated with a policy. That token is used to make all subsequent requests to Vault. " Tokens serve as the primary security feature for authorizing and authenticating requests.
The docs elaborate: " Tokens are the core method for authentication within Vault. Once authenticated, the client uses this token to access secrets and perform operations according to the attached policies. " Other options like ldap , pgp , path , key shard , and listener are unrelated to this role. Thus, F is correct.

NEW QUESTION # 114
You are using the Vault userpass auth method mounted at auth/userpass. How do you create a new user named " sally " with password " h0wN0wB4r0wnC0w " ? This new user will need the power-users policy.
Answer: B
Explanation:
To create a new user named "sally" with password "h0wN0wB4r0wnC0w" and the power-users policy, you would use the Vault userpass auth method mounted at auth/userpass. You would use the following command:
"vault write auth/userpass/users/sally password=h0wN0wB4r0wnC0w policies=power-users". This command would create a new user named "sally" with the specified password and policy. References :

NEW QUESTION # 115
Short-lived, dynamically generated secrets provide organizations with many benefits. Select the benefits from the options below. (Select four)
Answer: A,C,D,E
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Dynamic secrets in Vault are generated on-demand and have short lifespans, offering significant security and operational benefits:
* A. Unique Credentials per Instance: "Each application instance can generate its own credentials" isolates access, reducing the blast radius of a compromise. The documentation highlights: "This improves security by isolating access."
* B. On-Demand Existence: "Credentials only exist when needed" minimizes exposure time. Vault's design ensures "dynamic secrets do not exist until they are read," reducing theft risk.
* C. Least Privilege Enforcement: "Applications only have access to privileged accounts when needed" aligns with security best practices. "This helps enforce the principle of least privilege," per the docs.
* D. Invalidation of Leaked Credentials: "Credentials accidentally checked into a code repo or discovered in a text file are likely to be invalid" due to their short lifespan and revocation. "Dynamic secrets can be revoked immediately after use."
* Incorrect Option:
* E. Static Nature Misconception: "Dynamic credentials do not change" is false. The documentation counters: "Dynamic secrets change," enhancing security, but this may challenge legacy apps, not ease their use.
These benefits collectively enhance security by limiting credential exposure and scope.
