NEW QUESTION # 21
A Mule application deployed to a standardalone Mule runtime uses VM queues to publish messages to be consumed asynchronously by another flow.
In the case of a system failure, what will happen to in-flight messages in the VM queues that have been consumed?
Answer: C
Explanation:
In case of a system failure, in-flight messages in persistent VM queues that have been consumed will be processed after the system comes online. This is because persistent VM queues store messages on disk and guarantee delivery even if there is a system crash or restart. Therefore, any in-flight messages that have been consumed but not processed will be recovered from disk and processed when the system is back online. Reference: https://docs.mulesoft.com/mule-runtime/4.3/vm-connector#persistent-queues
NEW QUESTION # 22
Refer to the exhibit.
What action must be performed to log all the errors raised by the VM Connector?
Exhibit:
Answer: B
Explanation:
Mule uses Log4j 2 for runtime and application logging, and connector-specific log levels are configured in the application's log4j2.xml file. To configure the VM Connector's logger, the logger category is org.mule.
extensions.vm, and the logger declaration belongs under the < Loggers > element.
MuleSoft's VM Connector troubleshooting documentation provides the same configuration pattern for verbose logging:
< AsyncLogger name="org.mule.extensions.vm" level="DEBUG"/ >
inside < Loggers > . For this question, the objective is specifically to log connector events at the ERROR level, so the appropriate level is changed to ERROR while preserving the same logger category and structural location.
< Appenders > defines output destinations and formatting mechanisms such as files or consoles; it is not where logger categories and their levels are declared. Configuring the logging level directly inside the VM Connector configuration is also not supported because Mule connector logging is governed through Log4j configuration.
Therefore, adding the AsyncLogger for org.mule.extensions.vm under the < Loggers > section is the correct implementation.

NEW QUESTION # 23
Which configurations are required for HTTP Listener to enable mTLS authentication?
Answer: A
Explanation:
To enable mTLS authentication for HTTP Listener, the developer needs to set an appropriate keystore and truststore configuration for the listener. The keystore contains the certificate and private key of the Mule application that are used to prove its identity to clients. The truststore contains the certificates of trusted clients that are allowed to access the Mule application. Reference: https://docs.mulesoft.com/mule-runtime/4.3/tls-configuration#mutual-authentication
NEW QUESTION # 24
Refer to the exhibits.
A Mule application's pom.xml configures the Maven Resources plugin to exclude parsing binary files in the project's src/main/resources/certs directory.
Which configuration of this plugin achieves a successful build?
Exhibits - Options A and B:
Exhibits - Options C and D:
Answer: B
Explanation:
Resource filtering is designed primarily for textual resources in which Maven substitutes property expressions. Binary files such as PKCS#12 keystores and certificate files must not be passed through text filtering because filtering can corrupt their binary representation.
The Maven Resources Plugin provides the dedicated configuration element nonFilteredFileExtensions. Each additional extension is declared using a nested nonFilteredFileExtension. The plugin documentation specifically defines this parameter as the list of additional file extensions to which filtering must not be applied.
Option C correctly uses the documented structure:
< nonFilteredFileExtensions >
< nonFilteredFileExtension > p12 < /nonFilteredFileExtension >
< nonFilteredFileExtension > crt < /nonFilteredFileExtension >
< nonFilteredFileExtension > pem < /nonFilteredFileExtension >
< /nonFilteredFileExtensions >
This is important because the application's normal resource configuration can still use < filtering > true <
/filtering > for textual files while Maven leaves the listed certificate/keystore formats untouched.
The alternative constructs visible in the other exhibits, such as excludeFileExtensions or excludeBinaryFiles, are not the Maven Resources Plugin parameter used for this purpose.
Reference topics: Maven Resources Plugin; resource filtering; binary resources; nonFilteredFileExtensions; Mule Maven builds.
Official documentation: https://maven.apache.org/plugins/maven-resources-plugin/resources-mojo.html
NEW QUESTION # 25
Which properties are mandatory on the HTTP Connector configuration in order to use the OAuth 2.0 Authorization Code grant type for authentication?
Answer: D
Explanation:
The OAuth 2.0 Authorization Code grant requires several endpoints and client credentials because the Mule application participates in both the user authorization stage and the subsequent authorization-code-to-token exchange.
For the HTTP Request Connector, MuleSoft identifies the principal required configuration fields as the external callback URL, local authorization URL, authorization URL, client ID, client secret, and token URL.
The option refers to the token endpoint as the access token URL, which represents the same OAuth server endpoint used to exchange the authorization code for an access token.
The authorization URL redirects the resource owner to the authorization server. The local authorization URL initiates Mule's authorization process. The external callback URL identifies the publicly reachable callback through which the OAuth server returns the authorization code. The client ID and client secret authenticate the registered client application, while the token URL is used for the token exchange.
By contrast, the local callback URL is configurable but not mandatory in the same manner, and fields such as Response Access Token and Response Refresh Token are expressions for extracting provider-specific values rather than fundamental mandatory authorization-code grant parameters.
Reference topics: HTTP Connector Authentication; OAuth 2.0 Authorization Code Grant; Callback URLs; Token Endpoint.
