NEW QUESTION # 24
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 succeed if the CA's certificate is present in the JRE's default truststore.
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 succeed regardless of the CA
D. The HTTP Request operation will always fail regardless of the CA

Answer: A

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

NEW QUESTION # 25
An organization uses CloudHub to deploy all of its applications.
How can a common-global-handler flow be configured so that it can be reused across all of the organization's deployed applications?

A. Create a common-global-error-handler flow in all Mule Applications Refer to it flow-ref wherever needed.
B. Create a Mule plugin project
Create a common-global-error-handler flow inside the plugin project.
Use this plugin as a dependency in all Mute applications.
Import that configuration file in Mute applications.
C. Create a Mule daman project.
Create a common-global-error-handler flow inside the domain project.
Use this domain project as a dependency.
D. Create a Mule Plugin project
Create a common-global-error-handler flow inside the plugin project.
Use this plugin as a dependency in all Mule applications

Answer: D

Explanation:
Explanation
To configure a common-global-handler flow that can be reused across all of the organization's deployed applications, the developer should create a Mule Plugin project, create a common-global-error-handler flow inside the plugin project, and use this plugin as a dependency in all Mule applications. This way, the developer can import the common-global-error-handler flow in any application that needs it and avoid duplicating the error handling logic. References:
https://docs.mulesoft.com/mule-runtime/4.3/error-handling#global-error-handler

NEW QUESTION # 26
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 Connector
B. CloudHub REST API
C. Object Store v2 REST API
D. CloudHub Connector

Answer: C

Explanation:
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.
References: https://docs.mulesoft.com/object-store/osv2-apis

NEW QUESTION # 27
When implementing a synchronous API where the event source is an HTTP Listener, a developer needs to return the same correlation ID back to the caller in the HTTP response header.
How can this be achieved?

A. Configure a custom correlation policy
B. Enable the CorrelationID checkbox in the HTTP Listener configuration
C. NO action is needed as the correlation ID is returned to the caller in the response header by default
D. Enable the auto-generate CorrelationID option when scaffolding the flow

Answer: C

Explanation:
Explanation
When implementing a synchronous API where the event source is an HTTP Listener, Mule automatically propagates some message attributes between flows via outbound and inbound properties. One of these attributes is correlation ID, which is returned to the caller in the response header by default as MULE_CORRELATION_ID. References:
https://docs.mulesoft.com/mule-runtime/4.3/about-mule-message#message-attributes

NEW QUESTION # 28
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:200.
Body 'Error in processing your request
C. HTTP Status Code:500.
Body 'Error in processing your request
D. HTTP Status Code:500.
Body 'The HTTP CONNECTIVITY Error description

Answer: C

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 # 29
Which statement is true when using XML SDK for creating custom message processors?

A. Operations can be reused in recursive calls
B. All operations are public
C. 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
D. An XML SDK provides both inbound and outbound operations

Answer: B

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 # 30
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

Answer: A

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 # 31
A scatter-gather router is configured with four routes:Route A, B, C and D.
Route C false.

A. Payload failures['2']
B. Payload ['2']
C. Error,errorMessage,payload.failures['2']
D. Error,errorMesage.payload.results ['2']

Answer: C

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 # 32
Which plugin or dependency is required to unit test modules created with XML SDK?

A. MUnit Extensions Maven plugin
B. MUnit Maven plugin
C. Junit
D. XMLUnit

Answer: A

Explanation:
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. References:
https://docs.mulesoft.com/mule-sdk/1.1/xml-sdk#testing

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. Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself
D. Configure the application to send health data to an external system

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
An API has been developed and deployed to CloudHub Among the policies applied to this API is an allowlist of IP addresses. A developer wants to run a test in Anypoint Studio and does not want any policies applied because their workstation is not included in the allowlist.
What must the developer do in order to run this test locally without the policies applied?

A. Pass in the runtime parameter ''-Danpow.platform.gatekeeper=disabled''
B. Run the test as-s, with no changes because the Studio runtime will not attempt to connect to API Manager
C. Deactivate the API in API Manager so the Autodiscovery element will not find the application when it runs in Studio
D. Create a properties file specifically for local development and set the API instance ID to a value that is not used in API Manager

Answer: D

Explanation:
Explanation
To run a test locally without the policies applied, the developer should create a properties file specifically for local development and set the API instance ID to a value that is not used in API Manager. This way, the developer can use different configuration properties for different environments and avoid triggering API autodiscovery when running tests locally. API autodiscovery is a mechanism that associates an API implementation with its corresponding API specification and policies in API Manager based on its API instance ID. By setting this ID to a value that does not exist in API Manager, the developer can prevent API autodiscovery from finding and applying any policies to the local test. References:
https://docs.mulesoft.com/api-manager/2.x/api-auto-discovery-new-concept#configuring-api-autodiscovery
https://docs.mulesoft.com/mule-runtime/4.3/configuring-properties

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 ''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

Answer: A

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?

Answer: A

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 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. Pom.xml
B. Mule.artificact.json
C. Config.yaml
D. Settings.xml

Answer: A

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 # 38
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. Import a published API
B. Download RAML from Design Center'
C. Import RAML from local file
D. Generate a local RAML from anypoint Studio

Answer: A

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 # 39
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 to invoke the API and wait for a response
B. Use a Scheduler to check for a response every minute
C. Use an HTTP Connector inside Async scope to invoice the API and wait for a response
D. Expose an HTTP callback API in Mule and register it with the external system

Answer: D

Explanation:
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. References:
https://docs.mulesoft.com/mule-runtime/4.3/http-listener-ref#callback

NEW QUESTION # 40
Refer to the exhibit.

Based on the code snippet, schema,json file, and payload below, what is the outcome of the given code snippet when a request is sent with the payload?

A. The Mule flow will execute successfully with status code 204
B. The Mule flow will execute successfully with status code 200m and a response will display the message
'' Age in years which must equal to or greater than zero.''
C. The Mule flow will execute successfully with status code 200, and the response will be the JSON sent in request
D. The Mule flow will throw the exception 'JSON:SCHEMA_NOT_HONOURED

Answer: D

Explanation:
Explanation
Based on the code snippet, schema.json file, and payload below, the outcome of the given code snippet when a request is sent with the payload is that the Mule flow will throw the exception
'JSON:SCHEMA_NOT_HONOURED'. This is because the payload does not conform to the schema.json file, which specifies that age must be a number greater than or equal to zero. The payload has age as a string with a negative value, which violates the schema. Therefore, the validate-schema operation throws an error with type
'JSON:SCHEMA_NOT_HONOURED'. References:
https://docs.mulesoft.com/json-module/1.1/json-validate-schema

NEW QUESTION # 41
An API has been built to enable scheduling email provider. The front-end system does very little data entry validation, and problems have started to appear in the email that go to patients. A validate-customer'' flow is added validate the data.
What is he expected behavior of the 'validate-customer'' flow?

A. If the appointment date and customer name are invalid, a
SCHEDULE:INVALID_APPOINTMENT_DATE error is raised
B. If the email address is invalid, processing continues to see if the appointment data and customer name are also invalid
C. If only the email address Is invalid a VALIDATION.INVALID_EMAIL error is raised
D. If all of the values are invalid the last validation error is
raised:SCHEDULE:INVALID_CUSTOMER_NAME

Answer: C

Explanation:
Explanation
The validate-customer flow uses an until-successful scope to validate each field of the customer data. The until-successful scope executes its processors until they succeed or exhausts the maximum number of retries.
If any processor fails, it raises an error and stops executing the remaining processors. Therefore, if only the email address is invalid, a VALIDATION.INVALID_EMAIL error is raised and the validation of appointment date and customer name is skipped. References:
https://docs.mulesoft.com/mule-runtime/4.3/until-successful-scope

NEW QUESTION # 42
A Mule application uses API autodiscovery to access and enforce policies for a RESTful implementation.

A. Any of the APIkit generate implement flows
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. The name of the flow that has APlkit Console to receive all incoming RESTful operation requests.

Answer: C

Explanation:
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. References:
https://docs.mulesoft.com/api-manager/2.x/api-auto-discovery-new-concept#flowref

NEW QUESTION # 43
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 both the private and public keys to encrypt the data
B. The application needs the public key from the backend service to encrypt the data
C. The application needs to configure HTTPS TLS context information to encrypt the data
D. The application needs the private key from the backend service to encrypt the data

Answer: B

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.
