NEW QUESTION # 68
Although batch and service tokens share many characteristics, which of the following are true only about batch tokens? (Select three)
Answer: A,C,D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
Batch and service tokens differ in key ways, with these unique tobatch tokens:
* C. Maintain a single fixed TTL: "Batch tokens maintain a single fixed TTL," non-renewable, unlike service tokens.
* D. Valid across clusters: "They are valid for either the primary or any secondary clusters," enhancing flexibility in replicated setups.
* E. Not persisted to disk: "Batch tokens are not persisted to disk," reducing exposure risk.
* Incorrect Options:
* A. Can create child tokens: "Batch tokens cannot create child tokens," unlike service tokens.
* B. Renewable: "Batch tokens are not renewable," a key distinction from service tokens.
Batch tokens prioritize lightweight, ephemeral use.

* }
Answer: A,B,C,E
Explanation:
Comprehensive and Detailed In-Depth Explanation:
The API response provides authentication details. The Vault documentation states:
"When executing an authentication request to Vault, you will need to provide the credentials that will be used for authentication. Once successfully authenticated, Vault will return a bunch of information. The primary value that you need to retrieve from this response is the client_token, which can be queried from a JSON parsing tool (such as jq) by grabbing the value of .auth.client_token."
-Vault API Docs
* A,C,E,F: Correct per the response and endpoint (/auth/userpass).
* B: Incorrect; token_type is service, not batch:
"The returned token is a service token used for interacting with Vault's API on behalf of the authenticated user."
-Vault Concepts: Tokens
* D: Incorrect; accessors don't authenticate:
"The accessor value provided in the response is not typically used for direct authentication to Vault to retrieve secrets."
-Vault Concepts: Tokens

Vault API Docs
Vault Auth: Userpass
NEW QUESTION # 70
Your organization recently suffered a security breach on a specific application, and the security response team believes that MySQL database credentials were likely obtained during the event. The application generated the credentials using the database secrets engine in Vault mounted at the path database/. How can you quickly revoke all of the secrets generated by this secrets engine?
Answer: D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
To revoke all secrets from the database/ engine, use vault lease revoke -prefix. The Vault documentation states:
"If you need to revoke many leases, you can use vault lease revoke -prefix <prefix> and Vault will revoke all leases associated with the specified path. For example, you can revoke all leases associated with an entire database secrets engine by using vault lease revoke -prefix database/."
-Vault Commands: lease revoke
* D: Correct. Revokes all leases under database/:
"Using the command vault lease revoke -prefix database/ will revoke all the leases that have a prefix matching the specified path database/."
-Vault Commands: lease revoke
* A: Revokes tokens, not leases.
* B: Disables the engine, not existing secrets.
* C: Renews a specific lease, not revokes all.
References:
Vault Commands: lease revoke
Vault Secrets: Databases
NEW QUESTION # 71
What features are offered by the Vault Agent? (Select three)
Answer: B,C,D
Explanation:
Comprehensive and Detailed In-Depth Explanation:
TheVault Agentis a client-side daemon with these features:
* B. Templating: "Allows rendering of user-supplied templates by Vault Agent," integrating secrets into configs.
* C. Auto-auth: "Automatically authenticate to Vault and manage token renewal," simplifying auth workflows.
* D. Secret caching: "Allows client-side caching of responses," reducing Vault load.
* Incorrect Option:
* A. Auditing: Handled by Vault's audit devices, not Agent. "Auditing is typically handled by enabling audit devices." Reference:https://developer.hashicorp.com/vault/docs/v1.16.x/agent-and-proxy/agent
NEW QUESTION # 72
Your application cannot manage authentication with Vault, but it can communicate with a local service to retrieve secrets. What solution can enable your app to generate dynamic credentials from Vault?
Answer: B
Explanation:
Comprehensive and Detailed in Depth Explanation:
For an application that cannot manage authentication with Vault but can communicate with a local service, the Vault Proxy with Auto-Auth feature enabledis the optimal solution. The HashiCorp Vault documentation states that Vault Proxy can "act as a proxy between Vault and the application, optionally simplifying the authentication process." The Auto-Auth feature allows the proxy to handle authentication on behalf of the application, enabling it to generate dynamic credentials without the application needing to manage the authentication process directly. This aligns perfectly with the requirement of delegating authentication to a local service.
Vault Proxy with cachingimproves performance by caching responses but does not inherently handle authentication, missing the core need.Vault Agent with environment variable secret injectioninjects secrets into the application's environment but assumes the agent manages authentication, which the application cannot do.Vault Agent with templatinggenerates credentials based on templates but still requires authentication management, which the application cannot handle. Vault Proxy with Auto-Auth uniquely addresses this by offloading authentication responsibilities.
