Which type of cache invalidation does the Cache scope support without having to write any additional code?
- A. Write-through invalidation
- B. Time to live
- C. White-behind invalidation
- D. Notification-based invalidation
Answer: B
Explanation:
The Cache scope supports time to live (TTL) as a cache invalidation strategy without having to write any additional code. TTL specifies how long the cached response is valid before it expires and needs to be refreshed. The Cache scope also supports custom invalidation strategies using MEL or DataWeave expressions. Reference: https://docs.mulesoft.com/mule-runtime/4.3/cache-scope#cache_invalidation

Bioinfo System API is implemented and published to Anypoint Exchange. A developer wants to invoke this API using its REST Connector.
What should be added to the POM?
- A.
- B.
- C.
- D.
- E.
Answer: A
Explanation:
To invoke Bioinfo System API using its REST Connector, option E should be added to the pom.xml file. This option adds a dependency for Bioinfo System API REST Connector with its group ID, artifact ID, version, classifier, and type. The classifier specifies that it is a REST Connector (raml-client), and the type specifies that it is a Mule plugin (mule-plugin).

When a client and server are exchanging messages during the mTLS handshake, what is being agreed on during the cipher suite exchange?
- A. The TLS version
- B. An encryption algorithm
- C. The Public key format
- D. A protocol
Answer: B
Explanation:
A cipher suite is a set of cryptographic algorithms that are used to secure the communication between a client and a server. A cipher suite consists of four components: a key exchange algorithm, an authentication algorithm, an encryption algorithm, and a message authentication code (MAC) algorithm. During the cipher suite exchange, the client and the server agree on which encryption algorithm to use for encrypting and decrypting the data. Reference: https://docs.mulesoft.com/mule-runtime/4.3/tls-configuration#cipher-suites
NEW QUESTION # 40
A Mule application uses API autodiscovery to access and enforce policies for a RESTful implementation.
- A. The name of the flow that has APlkit Console to receive all incoming RESTful operation requests.
- B. Northing because flowRef is an optional attribute which can be passed runtime
- C. The name of the flow that has HTTP listener to receive all incoming RESTful operation requests
- D. Any of the APIkit generate implement flows
Answer: C
Explanation:
To use API autodiscovery to access and enforce policies for a RESTful implementation, flowRef must be set to the name of the flow that has HTTP listener to receive all incoming RESTful operation requests. This way, API autodiscovery can identify the API implementation and associate it with the corresponding API specification and policies in API Manager. The flow that has HTTP listener is usually the main flow that contains the APIKit Router. Reference: https://docs.mulesoft.com/api-manager/2.x/api-auto-discovery-new-concept#flowref

Retrieve the information from the log file.
Answer: B
Explanation:
To get the average number of requests and average response time of the Salesforce Connector, the developer should access Anypoint Monitoring's built-in dashboard, select a resource (such as an application or an API), and locate the information under the Connectors tab. The Connectors tab shows metrics for each connector used by the resource, such as average requests per minute, average response time, and failures. Reference: https://docs.mulesoft.com/monitoring/built-in-dashboard-reference
NEW QUESTION # 42
Multiple individual Mute application need to use the Mule Maven plugin to deploy to CloudHub.
The plugin configuration should .. reused where necessary and anything project, specific should be property-based.
Where should the Mule Maven details be configured?
- A. Settings, xml
- B. A parent pom.xml
- C. A Bill of Materials (BOM) parent pm
- D. Pom, xml
Answer: B
Explanation:
To reuse Mule Maven plugin configuration across multiple individual Mule applications, the developer should use a parent pom.xml file. A parent pom.xml file defines common configuration for one or more child projects that inherit from it. The developer can specify common properties and dependencies for all child projects in the parent pom.xml file, such as Mule Maven plugin configuration, and then reference them in each child project's pom.xml file using placeholders. Reference: https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#parent-pom https://maven.apache.org/guides/introduction/introduction-to-the-pom.html#Project_Inheritance
NEW QUESTION # 43
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?
- A. For any type of queue, the message will be lost
- B. For transient queues, the message will be processed after the system comes online
- C. For nay type of queue, the message will be processed after the system comes online
- D. For persistent queues, the message will be processed after the system comes online
Answer: D
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 # 44
Refer to the exhibit.
A developer generates the base scaffolding for an API in Anypoint Studio.
Which HTTP status code is returned while testing using the API Kit console if no values are entered in client-secret?
- A. HTTP status code:400
- B. HTTP status code:500
- C. HTTP status code:403
- D. HTTP status code:200
Answer: C
Explanation:
Based on the code snippet and schema.json file below, when testing using the API Kit console if no values are entered in client-secret, HTTP status code 403 (FORBIDDEN) is returned. This is because client-secret is defined as a required header parameter in schema.json file, which means that it must be present in every request. If no values are entered in client-secret, then it is equivalent to omitting this header parameter, which violates the schema and causes APIKit Router to return HTTP status code 403. Reference: https://docs.mulesoft.com/apikit/4.x/apikit-4-headers
NEW QUESTION # 45
Which configurations are required for HTTP Listener to enable mTLS authentication?
- A. Set an appropriate keystore configuration and use persistent connections for the listener
- B. Set an appropriate reconnection strategy and use persistent connections for the listener
- C. Set an appropriate keystore and truststore configuration for the listener
- D. Set an appropriate truststore configuration and reconnection strategy for the listener
Answer: C
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 # 46
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.
Answer: B
Explanation:
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. Reference: https://maven.apache.org/plugins/maven-resources-plugin/examples/filter.html https://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html
NEW QUESTION # 47
A custom policy needs to be developed to intercept all cutbound HTTP requests made by Mule applications.
Which XML element must be used to intercept outbound HTTP requests?
- A. http-policy:source
- B. htt-policy:operation
- C. http-policy:processor
- D. It is not possible to intercept outgoing HTTP requests, only inbound requests
Answer: A
Explanation:
The http-policy:processor element is used to intercept outbound HTTP requests made by Mule applications. It allows customizing the request before it is sent to the target API and modifying the response after it is received from the target API. Reference: https://docs.mulesoft.com/api-manager/2.x/policy-mule4-custom-policy#policy-xml-file
NEW QUESTION # 48
Which statement is true when using XML SDK for creating custom message processors?
- A. Operations can be reused in recursive calls
- B. Properties are fields defined by an end user of the XML SDK component and serve as a global configuration for the entire Mule project in which they are used
- C. An XML SDK provides both inbound and outbound operations
- D. All operations are public
Answer: B
Explanation:
When using XML SDK for creating custom message processors, all operations are public by default and can be used by any Mule application that imports them. There is no way to make an operation private or protected in XML SDK. Reference: https://docs.mulesoft.com/mule-sdk/1.1/xml-sdk#operations
NEW QUESTION # 49
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
Answer: D
Explanation:
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. Reference: https://docs.mulesoft.com/mule-runtime/4.3/java-module-reference#add-the-java-module-to-your-project https://docs.mulesoft.com/mule-runtime/4.3/java-module-reference#invoke-java-code
NEW QUESTION # 50
A Mule application includes a subflow containing a Scatter.Gather scope. Within each log of the Scatter.Gatter. an HTTP connector calls a PUT endpoint to modify records in different upstream system. The subflow is called inside an Unit successful scope to retry if a transitory exception is raised.
A technical spike is being performed to increase reliability of the Mule application.
Which steps should be performed within the Mule flow above the ensure idempontent behavior?
- A. Ensure an error-handling flow performs corrective actions to roll back all changes if any leg of the Scatter-Gather fails
- B. None, the flow already exhibits idempotent behavior
- C. Remove the Put requests from the Scatter-Getter and perform them sequentially
- D. Change the PUT requests inside the Scatter-Gather to POST requests
Answer: A
Explanation:
To ensure idempotent behavior within a Mule flow that contains a subflow with a Scatter-Gather scope, the developer should ensure an error-handling flow performs corrective actions to roll back all changes if any leg of the Scatter-Gather fails. Idempotency means that multiple identical requests have the same effect as a single request. Therefore, if one of the HTTP requests inside the Scatter-Gather fails, the error-handling flow should undo any changes made by other successful requests to ensure consistency and avoid partial updates. Reference: https://docs.mulesoft.com/mule-runtime/4.3/scatter-gather-concept https://docs.mulesoft.com/mule-runtime/4.3/error-handling
NEW QUESTION # 51
A company has been using CI/CD. Its developers use Maven to handle build and deployment activities.
What is the correct sequence of activities that takes place during the Maven build and deployment?
- A. Validate, initialize, compile, test package, verify, install, deploy
- B. Validate, initialize, compile, package, test, install, verify, verify, deploy
- C. Validation, initialize, compile, test, package, install verify, deploy
- D. Initialize, validate, compute, test, package, verify, install, deploy
Answer: A
Explanation:
The correct sequence of activities that takes place during the Maven build and deployment is validate, initialize, compile, test package, verify, install, deploy. These are Maven lifecycle phases that define a sequence of goals to execute during a build process. Each phase represents a stage in the build lifecycle and can have zero or more goals bound to it. Reference: https://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html
NEW QUESTION # 52
Mule application A is deployed to CloudHub and is using Object Store v2. Mute application B is also deployed to CloudHub.
Which approach can Mule application B use to remove values from Mule application A'S Object Store?
- A. Object Store v2 REST API
- B. Object Store Connector
- C. CloudHub REST API
- D. CloudHub Connector
Answer: A
Explanation:
To remove values from Mule application A's Object Store v2, Mule application B can use Object Store v2 REST API. This API allows performing operations on Object Store v2 resources using HTTP methods, such as GET, POST, PUT, and DELETE. Mule application B can use the DELETE method to remove values from Mule application A's Object Store v2 by specifying the object store ID and the key of the value to delete.
