- C. MUnit Maven plugin
- D. MUnit Extensions Maven plugin
Answer: D
Explanation:
To unit test modules created with XML SDK, the developer needs to use the MUnit Extensions Maven plugin. This plugin allows testing XML SDK modules using MUnit by adding a dependency to the module under test and using a custom processor tag to invoke it. Reference: https://docs.mulesoft.com/mule-sdk/1.1/xml-sdk#testing
NEW QUESTION # 29
Refer to the exhibit.
What action must be performed to log all the errors raised by the VM Connector?
- A. Add <AsyncLOgger name='orgroute.extensions vm' level=ERROR'/> inside the Appenders tag
- B. Add <AsyncLOgger name='orgroute.extensions vm' level=ERROR'I> inside the Logger tag
- C. Nothing, as error-level events are automatically logged
- D. Configure <Logger level-'ERROR'/> inside the VM Connector configuration
Answer: A
Explanation:
To log all the errors raised by the VM Connector, the developer needs to add an async logger with the name 'org.mule.extension.vm' and the level 'ERROR' inside the appenders tag of the log4j2.xml file. This will enable logging all error-level events generated by the VM Connector to the console appender. Reference: https://docs.mulesoft.com/mule-runtime/4.3/logging-in-mule#configuring-custom-logging-settings
NEW QUESTION # 30
A Mule implementation uses a HTTP Request within an Unit Successful scope to connect to an API.
How should a permanent error response like HTTP:UNAUTHORIZED be handle inside Until Successful to reduce latency?
- A. Configure retrying until a MULERETRY_EXHAUSTED error is raised or the API responds back with a successful response.
- B. In Until Successful configuration, set the retry count to 1 for error type HTTP: UNAUTHORIZED.
- C. Put the HTTP Request inside a try scope in Unit Successful.
In the error handler, use On Error Propagate to catch permanent errors like HTTP UNAUTHORIZED. - D. Put the HTTP Request inside a try scope in Unit Successful.
In the error handler, use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED.
Answer: D
Explanation:
To handle a permanent error response like HTTP:UNAUTHORIZED inside Until Successful, the developer should put the HTTP Request inside a try scope in Unit Successful, and use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED in the error handler. This way, the developer can avoid retrying requests that will always fail due to a permanent error, and reduce latency. On Error Continue allows the flow to continue processing after handling the error. Reference: https://docs.mulesoft.com/mule-runtime/4.3/until-successful-scope https://docs.mulesoft.com/mule-runtime/4.3/on-error-continue-concept
NEW QUESTION # 31
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 nay type of queue, the message will be processed after the system comes online
- C. For persistent queues, the message will be processed after the system comes online
- D. For transient queues, the message will be processed after the system comes online
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 # 32
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 exchanhe.
Create different Anypoint MQ queues meant for each of the other subscribing systems.Bind the exchange with each of the queues. - B. Publish the gate change notification to an Anypoint MC queue
Have each client subscribe directly to the queue - 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 MQ queue.
Create different anypoint MQ exchange meant for each of the other subscribing systems Bind the queue with each of the exchanges
Answer: A
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. Reference: https://docs.mulesoft.com/anypoint-mq/3.x/anypoint-mq-exchanges
NEW QUESTION # 33
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. Install libraries in a local repository and refer to it in the pm.xml file
- B. Refer to JAR files in the code
- C. Create the Java code in your project and invoice the data from the code
- D. Include the libraries writes deploying the code into the runtime
Answer: A
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 # 34
A Mule application need to invoice an API hosted by an external system to initiate a process. The external API takes anywhere between one minute and 24 hours to compute its process.
Which implementation should be used to get response data from the external API after it completes processing?
- A. Use an HTTP Connector inside Async scope to invoice the API and wait for a response
- B. Use an HTTP Connector to invoke the API and wait for a response
- C. Expose an HTTP callback API in Mule and register it with the external system
- D. Use a Scheduler to check for a response every minute
Answer: C
Explanation:
To get response data from the external API after it completes processing, the developer should expose an HTTP callback API in Mule and register it with the external system. This way, the external API can invoke the callback API with the response data when it is ready, instead of making the Mule application wait for a long time or poll for a response repeatedly. Reference: https://docs.mulesoft.com/mule-runtime/4.3/http-listener-ref#callback
NEW QUESTION # 35
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 ''Before Test Case'' To collect data from Flow-1 test cases before running Flow-2 test cases
- B. Use 'After Test Case' to produce the data needed from Flow-1 test cases to pass to Flow-2 test cases
- C. Chain together the test suites and test cases for Flow-1 and Flow-2
- D. Use ''Set Event to pass the input that is needed, and keep the test cases for Flow-1 and Flow-2 independent
Answer: D
Explanation:
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. Reference: https://docs.mulesoft.com/munit/2.3/munit-test-flow
NEW QUESTION # 36
An order processing system is composed of multiple Mule application responsible for warehouse, sales and shipping. Each application communication using Anypoint MQ. Each message must be correlated against the original order ID for observability and tracing.
How should a developer propagate the order ID as the correlation ID across each message?
- A. Set a custom Anypoint MQ user property to propagate the order ID and set the correlation ID in the receiving applications.
- B. Use the underlying HTTP request of Anypoint MQ to set the 'X-CORRELATION_ID' header to the order ID
- C. Use the default correlation ID, Anypoint MQ will sutomatically propagate it.
- D. Wrap all Anypoint MQ Publish operations within a With CorrelationID scope from the Tracing module, setting the correlation ID to the order ID
Answer: D
Explanation:
To propagate the order ID as the correlation ID across each message using Anypoint MQ, the developer should wrap all Anypoint MQ Publish operations within a With CorrelationID scope from the Tracing module, setting the correlation ID to the order ID. The With CorrelationID scope allows setting a custom correlation ID for any event that occurs within it. The Tracing module also enables distributed tracing across different Mule applications and services using Anypoint Monitoring. Reference: https://docs.mulesoft.com/tracing-module/1.0/tracing-module-reference#with-correlation-id-scope https://docs.mulesoft.com/tracing-module/1.0/tracing-module-concepts
NEW QUESTION # 37
Refer to the exhibit.
The flow name is ''implementation'' with code for the MUnit test case.
When the MUnit test case is executed, what is the expected result?
- A. The test case passes
- B. The test case fails with an unexpected error type
- C. The test case fails with an assertion error
- D. The test throws an error and does not start
Answer: C
Explanation:
Based on the code snippet and MUnit test case below, when the MUnit test case is executed, the expected result is that the test case fails with an assertion error. This is because the assert-equals processor compares two values for equality, and fails if they are not equal. In this case, the expected value is 'Hello World', but the actual value returned by the implementation flow is 'Hello Mule'. Therefore, the assertion fails and an error is thrown. Reference: https://docs.mulesoft.com/munit/2.3/assert-equals-processor
NEW QUESTION # 38
A Mule application defines as SSL/TLS keystore properly 'tis,keystore.keyPassword'' as secure.
How can this property be referenced to access its value within the application?
- A. #{secure::tiskeystore,keyPassowrd}
- B. p{secure::tiskeystore,keyPassowrd}
- C. ${secure::tiskeystore,keyPassowrd}
- D. ${secure::tiskeystore,keyPassowrd}
Answer: C
Explanation:
secure::tiskeystore,keyPassowrd∗∗ShortExplanationofCorrectAnswerOnly:Toreferenceasecurepropertyvaluewithintheapplication,thedeveloperneedstousethesyntax{secure::}. In this case, the property name is tiskeystore,keyPassword, so the correct syntax is ${secure::tiskeystore,keyPassowrd}. Reference: https://docs.mulesoft.com/mule-runtime/4.3/secure-configuration-properties#referencing-secure-properties
NEW QUESTION # 39
A Mule application contain two policies Policy A and Policy A has order1, and Policy B has order 2. Policy A Policy B, and a flow are defined by he configuration below.
When a HTTP request arrives at the Mule application's endpoint, what will be the execution order?
- A. F1, B1, A1, A2, B2
- B. A1, B1, F1, B2, A2
- C. F1, A1, B1, B2, A2
- D. B1, A1, F1, A2, B2
Answer: B
Explanation:
Based on the configuration below, when a HTTP request arrives at the Mule application's endpoint, the execution order will be A1, B1, F1, B2, A2. This is because policies are executed before and after the API implementation flow according to their order attribute. Policy A has order 1, which means it is executed first before Policy B, which has order 2. The flow is executed after both policies are executed before the flow. Then, Policy B is executed after the flow before Policy A is executed after the flow. Reference: https://docs.mulesoft.com/api-manager/2.x/policies-policy-order
NEW QUESTION # 40
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. A parent pom.xml
- B. A Bill of Materials (BOM) parent pm
- C. Settings, xml
- D. Pom, xml
Answer: A
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 # 41
When a client and server are exchanging messages during the mTLS handshake, what is being agreed on during the cipher suite exchange?
- A. The Public key format
- B. An encryption algorithm
- C. The TLS version
- 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 # 42
Refer to the exhibit.
A Mute Object Store is configured with an entry TTL of one second and an expiration interval of 30 seconds.
What is the result of the flow if processing between os'store and os:retrieve takes 10 seconds?
- A. originalPayload
- B. nullPayload
- C. OS:KEY_NOT_FOUND
- D. testPayload
Answer: B
Explanation:
The result of the flow is nullPayload if processing between os:store and os:retrieve takes 10 seconds. This is because the entry TTL of the object store is one second, which means that any stored value expires after one second and is removed from the object store. The expiration interval of 30 seconds only determines how often the object store checks for expired values, but it does not affect the TTL. Therefore, when os:retrieve tries to get the value after 10 seconds, it returns nullPayload because the value has already expired and been removed. Reference: https://docs.mulesoft.com/object-store/osv2-faq#how-does-the-time-to-live-work
NEW QUESTION # 43
Which statement is true when working with correlation IDS?
- A. The HTTP Listener regenerates correlation IDs regardless of the HTTP request
- B. The HTTP Listener generates correlation IDS unless a correlation ID is received in the HTTP request
- C. The Anypoint MQ Connector automatically propagates correlation IDS
- D. The VM Connector does not automatically propagate correction IDs
Answer: B
Explanation:
When working with correlation IDs, the HTTP Listener generates correlation IDs unless a correlation ID is received in the HTTP request. In that case, it propagates the received correlation ID throughout the flow execution. Correlation IDs are used to track events across different flows or applications. Reference: https://docs.mulesoft.com/mule-runtime/4.3/about-mule-message#message-attributes
NEW QUESTION # 44
A mule application exposes and API for creating payments. An Operations team wants to ensure that the Payment API is up and running at all times in production.
Which approach should be used to test that the payment API is working in production?
- A. Configure the application to send health data to an external system
- B. Monitor the Payment API directly sending real customer payment data
- C. Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API
- D. Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself
Answer: C
Explanation:
To test that the payment API is working in production, the developer should create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API. This way, the developer can isolate the health check endpoint from the API traffic and avoid affecting the performance or availability of the API. The health check endpoint should return a simple response that indicates the status of the API, such as OK or ERROR. Reference: https://docs.mulesoft.com/api-functional-monitoring/afm-create-monitor#create-a-monitor
NEW QUESTION # 45
The HTTP Request operation raises an HTTP CONNECTIVITY error.
Which HTTP status code and body are returned to the web client?
- A. HTTP Status Code:200.
Body 'Error in processing your request - B. HTTP Status Code:500.
Body 'The HTTP CONNECTIVITY Error description - C. HTTP Status Code:500.
Body 'Error in processing your request - D. HTTP Status Code:500.
Body 'Error in processing your request
Answer: C
Explanation:
When the HTTP Request operation raises an HTTP CONNECTIVITY error, it triggers an on-error-continue handler that sets a payload with 'Error in processing your request'. Since no status code is explicitly set in this handler, it defaults to 500 (INTERNAL SERVER ERROR). Therefore, the web client receives an HTTP response with status code 500 and body 'Error in processing your request'. Reference: https://docs.mulesoft.com/mule-runtime/4.3/error-handling#on-error-continue
NEW QUESTION # 46
The Center for Enablement team published a common application as a reusable module to the central Nexus repository.
How can the common application be included in all API implementations?
- A. Add a Maven dependency in the POM file with jar as <classifier>
- B. Add a Maven dependency in the PCM file with multiple-plugin as <classifier>
- C. Copy the common application's source XML file and out it in a new flow file in the src/main/mule folder
- D. Download the common application from Naxus and copy it to the src/main/resources folder in the API
Answer: A
Explanation:
To include a common application as a reusable module in all API implementations, the developer should add a Maven dependency in the POM file with jar as <classifier>. This way, the developer can reuse Mule code from another application by packaging it as a JAR file and adding it as a dependency in the POM file of the API implementation. The classifier element specifies that it is a JAR file. Reference: https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#add-a-maven-dependency-to-the-pom-file
NEW QUESTION # 47
A scatter-gather router is configured with four routes:Route A, B, C and D.
Route C false.
- A. Payload failures['2']
- B. Error,errorMessage,payload.failures['2']
- C. Payload ['2']
- D. Error,errorMesage.payload.results ['2']
Answer: D
Explanation:
The result of accessing route C failure is Error,errorMessage,payload.failures['2']. This is because a scatter-gather router returns an aggregated message that contains an array of results from each route and an array of failures from each route. The failures array contains error objects with information about each failed route execution. To access route C failure, which is the third route (index 2), the developer needs to use Error.errorMessage.payload.failures['2'] expression. Reference: https://docs.mulesoft.com/mule-runtime/4.3/scatter-gather-reference#scatter-gather-output

- B. Monitor the Payment API directly sending real customer payment data
- C. Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API
- D. Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself
Answer: C
NEW QUESTION # 49
Which properties are mandatory on the HTTP Connector configuration in order to use the OAuth 2.0 Authorization Code grant type for authentication?
- A. External callback URL, access token URL, client ID, response refresh token
- B. External callback URL, access token URL, local authorization URL, authorization URL, client ID, client secret
- C. External callback URL, access token URL, client ID response access token
- D. Token URL, authorization URL, client ID, client secret local callback URL
Answer: B
Explanation:
To use the OAuth 2.0 Authorization Code grant type for authentication, the HTTP Connector configuration requires the following properties: token URL, authorization URL, client ID, client secret, and local callback URL. The token URL is the endpoint of the authorization server that provides access tokens. The authorization URL is the endpoint of the authorization server that initiates the user consent flow. The client ID and client secret are the credentials of the Mule application registered with the authorization server. The local callback URL is the endpoint of the Mule application that receives the authorization code from the authorization server. Reference: https://docs.mulesoft.com/http-connector/1.6/http-authentication#oauth-2-0
NEW QUESTION # 50
A new Mule project has been created in Anypoint Studio with the default settings.
Which file inside the Mule project must be modified before using Maven to successfully deploy the application?
- A. Mule.artificact.json
- B. Pom.xml
- C. Config.yaml
- D. Settings.xml
Answer: B
Explanation:
To use Maven to successfully deploy the application, the developer needs to modify the pom.xml file inside the Mule project. The pom.xml file contains the configuration and dependencies of the Mule application, as well as the deployment information such as the CloudHub region, environment, and worker size. The developer needs to specify these properties in the pom.xml file before using Maven to deploy the application. Reference: https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#application-deployment-descriptor
NEW QUESTION # 51
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 private 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 public key from the backend service to encrypt the data
- D. The application needs to both the private and public keys to encrypt the data
Answer: C
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. Reference: https://docs.mulesoft.com/mule-runtime/4.3/cryptography-pgp
NEW QUESTION # 52
Refer to the exhibit.
When creating a new project, which API implementation allows for selecting the correct API version and scaffolding the flows from the API specification?
- A. Generate a local RAML from anypoint Studio
- B. Import RAML from local file
- C. Download RAML from Design Center
- D. Import a published API
Answer: C
Explanation:
To create a new project that selects the correct API version and scaffolds the flows from the API specification, the developer should import a published API. This option allows importing an API specification that has been published to Anypoint Exchange or Design Center, and selecting a specific version of that API specification. The developer can also choose to scaffold flows based on that API specification. Reference: https://docs.mulesoft.com/apikit/4.x/apikit-4-new-project-task
