NEW QUESTION # 30
The flow is invoicing a target API. The API's protocol is HTTPS. The TLS configuration in the HTTP Request Configuration global element is set to None. A web client submits a request to
http:localhost:8081/vehicles.
If the certificate of the target API is signed by a certificate authority (CA), what is true about the HTTP Request operation when the flow executes?
- A. The HTTP Request operation will always succeed regardless of the CA
- B. The HTTP Request operation will succeed if the CA'S certificate is present in the JRE's default keystore
- C. The HTTP Request operation will always fail regardless of the CA
- D. The HTTP Request operation will succeed if the CA's certificate is present in the JRE's default truststore.
Answer: D
Explanation:
Explanation
The HTTP Request operation will use the default truststore of the JRE to validate the certificate of the target API. If the CA's certificate is present in the truststore, the operation will succeed. Otherwise, it will fail with a handshake exception. References: https://docs.mulesoft.com/mule-runtime/4.3/tls-configuration#tls-default

What is the result of the Mule Maven Plugin configuration of the value of property its,keystorePassoword in CloudHub 2.0?
- A. Runtime Manager masks the value
- B. CloudHub encrypts the value
- C. The Mule server encrypts the value
- D. Anypoint Studio secures the value
Answer: A
Explanation:
Explanation
The result of the Mule Maven Plugin configuration of the value of property its,keystorePassword in CloudHub
2.0 is that Runtime Manager masks the value. This means that Runtime Manager hides or obscures the value from anyone who views it in Runtime Manager or Anypoint Platform. References:

NEW QUESTION # 32
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: B
Explanation:
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. References:
https://docs.mulesoft.com/mule-runtime/4.3/scatter-gather-reference#scatter-gather-output
NEW QUESTION # 33
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. Monitor the Payment API directly sending real customer payment data
- B. Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API
- C. Configure the application to send health data to an external system
- D. Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself
Answer: B
Explanation:
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. References:
https://docs.mulesoft.com/api-functional-monitoring/afm-create-monitor#create-a-monitor
NEW QUESTION # 34
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. F1, A1, B1, B2, A2
- C. B1, A1, F1, A2, B2
- D. A1, B1, F1, B2, A2
Answer: D
Explanation:
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. References:
https://docs.mulesoft.com/api-manager/2.x/policies-policy-order
NEW QUESTION # 35
A developer has created the first version of an API designed for business partners to work commodity prices.
What should developer do to allow more than one major version of the same API to be exposed by the implementation?
- A. In Anypoint Studio, generate scaffolding from the RAML, and the modify the <http:listerner> in the generated flows to include a parameter to replace the version number
- B. In Design Center, open the RAML and modify baseUn to include a variable that indicates the version number
- C. In Anypoint Studio, generate scaffolding from the RAML, and then modify the flow names generated by APIKit to include a variable with the major version number
- D. In Design Center, open the RAML and modify each operation to include the major version number
Answer: B
Explanation:
Explanation
To allow more than one major version of the same API to be exposed by the implementation, the developer should modify the baseUri property in the RAML file to include a variable that indicates the version number.
The baseUri property defines the base URL of the API and can include variables that are replaced with actual values when mocking or deploying the API. By using a variable for the version number, the developer can expose different versions of the API using different base URLs and avoid conflicts or confusion. References:
https://docs.mulesoft.com/api-designer/design-modify-raml-specs#baseuri

NEW QUESTION # 36
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: D
Explanation:
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. References:
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 # 37
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. Initialize, validate, compute, test, package, verify, install, deploy
- B. Validation, initialize, compile, test, package, install verify, deploy
- C. Validate, initialize, compile, package, test, install, verify, verify, deploy
- D. Validate, initialize, compile, test package, verify, install, deploy
Answer: D
Explanation:
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. References:

NEW QUESTION # 38
A Mule application for processing orders must log the order ID for every log message output.
What is a best practice to enrich every log message with the order ID?
- A. Use the Tracing module to set logging variables with a Mapped Diagnostic Context
- B. Create a custom XML SDK component to wrap the logger processor and automatically add the order ID within the connector
- C. Use flow variables within every logger processor to log the order ID
- D. Set a flow variable and edit the log4/2.xml file to output the variable as part of the message pattern
Answer: A
Explanation:
Explanation
To enrich every log message with the order ID, the developer should use the Tracing module to set logging variables with a Mapped Diagnostic Context (MDC). The Tracing module allows adding custom key-value pairs to log messages using MDC variables. The developer can use Set Logging Variables operation to set the order ID as an MDC variable and then use it in any logger processor within the same thread or event.
References: https://docs.mulesoft.com/tracing-module/1.0/tracing-module-reference#set-logging-variables
NEW QUESTION # 39
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 a published API
- C. Download RAML from Design Center'
- D. Import RAML from local file
Answer: B
Explanation:
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. References:
https://docs.mulesoft.com/apikit/4.x/apikit-4-new-project-task
NEW QUESTION # 40
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:200
- D. HTTP status code:403
Answer: D
Explanation:
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. References:
https://docs.mulesoft.com/apikit/4.x/apikit-4-headers
NEW QUESTION # 41
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:500.
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:200.
Body 'Error in processing your request
Answer: A
Explanation:
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'. References:
https://docs.mulesoft.com/mule-runtime/4.3/error-handling#on-error-continue
NEW QUESTION # 42
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:processor
- B. http-policy:source
- C. It is not possible to intercept outgoing HTTP requests, only inbound requests
- D. htt-policy:operation
Answer: A
Explanation:
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. References:
https://docs.mulesoft.com/api-manager/2.x/policy-mule4-custom-policy#policy-xml-file
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 nay type of queue, the message will be processed after the system comes online
- C. For transient queues, 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:
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.
References: https://docs.mulesoft.com/mule-runtime/4.3/vm-connector#persistent-queues
NEW QUESTION # 44
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. Config.yaml
- C. Settings.xml
- D. Pom.xml
Answer: D
Explanation:
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.
References: https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#application-deployment-descriptor
NEW QUESTION # 45
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. Download the common application from Naxus and copy it to the src/main/resources folder in the API
- B. Add a Maven dependency in the POM file with jar 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. Add a Maven dependency in the PCM file with multiple-plugin as <classifier>
Answer: B
Explanation:
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. References:
https://docs.mulesoft.com/mule-runtime/4.3/mmp-concept#add-a-maven-dependency-to-the-pom-file
NEW QUESTION # 46
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. nullPayload
- B. originalPayload
- C. testPayload
- D. OS:KEY_NOT_FOUND
Answer: A
Explanation:
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.

Select a resource.
Locate the information under Log Manager < Raw Data. - D. Change the API Implementation to capture the information in the log.
Retrieve the information from the log file.
Answer: A
Explanation:
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. References:
https://docs.mulesoft.com/monitoring/built-in-dashboard-reference
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. All operations are public
- D. An XML SDK provides both inbound and outbound operations
Answer: C
Explanation:
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. References: https://docs.mulesoft.com/mule-sdk/1.1/xml-sdk#operations
NEW QUESTION # 49
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. Chain together the test suites and test cases for Flow-1 and Flow-2
- B. Use 'After Test Case' to produce the data needed from Flow-1 test cases to pass to Flow-2 test cases
- C. Use ''Before Test Case'' To collect data from Flow-1 test cases before running Flow-2 test cases
- 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:
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. References: https://docs.mulesoft.com/munit/2.3/munit-test-flow
NEW QUESTION # 50
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 throws an error and does not start
- D. The test case fails with an assertion error
Answer: D
Explanation:
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. References: https://docs.mulesoft.com/munit/2.3/assert-equals-processor
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 to configure HTTPS TLS context information to encrypt the data
- B. The application needs the private key from the backend service 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:
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. References: https://docs.mulesoft.com/mule-runtime/4.3/cryptography-pgp
NEW QUESTION # 52
Refer to the exhibit.
What is the result if ''Insecure'' selected as part of the HTTP Listener configuration?
- A. The HTTP Lister will accept any unauthenticated request
- B. Mutual TLS authentication will be enabled between this HTTP Listener and an HTTP client
- C. The HTTP Listener will trust any certificate presented by the HTTP client
- D. The HTTP listener will only accept HTTP requests
Answer: D
Explanation:
Explanation
Based on the exhibit below, if 'Insecure' is selected as part of the HTTP Listener configuration, the HTTP listener will only accept HTTP requests. This means that no TLS context will be configured for this listener and no encryption or authentication will be applied to incoming requests. The protocol attribute of this listener will be set to HTTP instead of HTTPS. References:
https://docs.mulesoft.com/http-connector/1.6/http-listener-ref#insecure
