A developer is working on a project that requires encrypting all data before sending it to a backend application. To accomplish this, the developer will use PGP encryption in the Mule 4 Cryptography module.
What is required to encrypt the data before sending it to the backend application?
A. The application needs the public key from the backend service to encrypt the data
B. The application needs to configure HTTPS TLS context information to encrypt the data
C. The application needs the private key from the backend service to encrypt the data
D. The application needs to both the private and public keys to encrypt the data
正解：A
解説：
Explanation
To encrypt the data before sending it to the backend application using PGP encryption, the application needs the public key from the backend service. PGP encryption uses a public-key cryptography system, which means that each party has a pair of keys: a public key and a private key. The public key is used to encrypt data, and the private key is used to decrypt data. Therefore, to encrypt data for a specific recipient (the backend service), the application needs to use the recipient's public key. The recipient can then use its own private key to decrypt the data.

In a Mule project, Flow-1 contains a flow-ref to Flow-2 depends on data from Flow-1 to execute successfully.
Which action ensures the test suites and test cases written for Flow-1 and Flow-2 will execute successfully?
A. Use ''Set Event to pass the input that is needed, and keep the test cases for Flow-1 and Flow-2 independent
B. Use ''Before Test Case'' To collect data from Flow-1 test cases before running Flow-2 test cases
C. Chain together the test suites and test cases for Flow-1 and Flow-2
D. Use 'After Test Case' to produce the data needed from Flow-1 test cases to pass to Flow-2 test cases
正解：A
解説：
To ensure the test suites and test cases written for Flow-1 and Flow-2 will execute successfully, the developer should use a Set Event processor to pass the input that is needed by Flow-2, and keep the test cases for Flow-1 and Flow-2 independent. This way, the developer can isolate the testing of each flow and avoid coupling them together. References:https://docs.mulesoft.com/munit/2.3/munit-test-flow

A heathcare customer wants to use hospital system data, which includes code that was developed using legacy tools and methods. The customer has created reusable Java libraries in order to read the data from the system.
What is the most effective way to develop an API retrieve the data from the hospital system?
A. Include the libraries writes deploying the code into the runtime
B. Refer to JAR files in the code
C. Create the Java code in your project and invoice the data from the code
D. Install libraries in a local repository and refer to it in the pm.xml file
正解：D
解説：
To develop an API that retrieves data from a hospital system using reusable Java libraries, the developer should install libraries in a local repository and refer to it in the pom.xml file. This way, the developer can use Maven to manage dependencies and invoke Java code from Mule applications using Java Module operations.

A Flight Management System publishes gate change notification events whenever a flight's arrival gate changes. Other systems, including Baggage Handler System. Inflight Catering System and Passenger Notifications System, must each asynchronously receive the same gate change notification to process the event according.
Which configuration is required in Anypoint MQ to achieve this publish/subscribe model?
A. Publish the gate change notification to an Anypoint MQ queue.
Create different anypoint MQ exchange meant for each of the other subscribing systems Bind the queue with each of the exchanges
B. Publish the gate change notification to an Anypoint MQ exchanhe.
Create different Anypoint MQ queues meant for each of the other subscribing systems.
Bind the exchange with each of the queues.
C. Publish each client subscribe directly to the exchange.
Have each client subscribe directly to the queue.
D. Publish the gate change notification to an Anypoint MC queue
Have each client subscribe directly to the queue
正解：B
解説：
Explanation
To achieve a publish/subscribe model using Anypoint MQ, where each system receives the same gate change notification event, the developer should publish the gate change notification to an Anypoint MQ exchange, create different Anypoint MQ queues meant for each of the other subscribing systems, and bind the exchange with each of the queues. An exchange is a message routing agent that can send messages to different queues based on predefined criteria. By binding an exchange with multiple queues, each queue receives a copy of every message sent to that exchange. Therefore, each system can subscribe to its own queue and receive every gate change notification event. References: https://docs.mulesoft.com/anypoint-mq/3.x/anypoint-mq-exchanges

Refer to the exhibit.
A Mule application 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?
A.
B.
C.
D.
正解：B
解説：
To configure the Maven Resources plugin to exclude parsing binary files in the project's src/main/resources/certs directory, option C should be used. This option specifies that any files with .cer or .jks extensions under the certs directory should be excluded from filtering. Filtering is a process of replacing placeholders with actual values in resource files during the build process. Binary files should not be filtered because they may become corrupted or unusable.
