Question 1

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?

AIn Design Center, open the RAML and modify each operation to include the major version number

BIn 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

CIn Design Center, open the RAML and modify baseUn to include a variable that indicates the version number

DIn 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

Answer : C

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.

Question 2

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?

AUse the underlying HTTP request of Anypoint MQ to set the 'X-CORRELATION_ID' header to the order ID

BSet a custom Anypoint MQ user property to propagate the order ID and set the correlation ID in the receiving applications.

CUse the default correlation ID, Anypoint MQ will sutomatically propagate it.

DWrap all Anypoint MQ Publish operations within a With CorrelationID scope from the Tracing module, setting the correlation ID to the order ID

Answer : D

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.

Question 3

A company deploys 10 public APIs to CloudHub. Each API has its individual health endpoint defined. The platform operation team wants to configure API Functional Monitoring to monitor the health of the APIs periodically while minimizing operational overhead and cost.

How should API Functional Monitoring be configured?

AFrom one public location with each API in its own schedule

BFrom one private location with all 10 APIs in a single schedule

CFrom one public location with all 10 APIs in a single schedule

DFrom 10 public locations with each API in its own schedule

Answer : C

To configure API Functional Monitoring to monitor the health of 10 public APIs periodically while minimizing operational overhead and cost, the developer should use one public location with all 10 APIs in a single schedule. A public location is a worker that runs in a CloudHub shared environment, which is cheaper and easier to maintain than a private location. A single schedule allows running all 10 APIs tests at the same time and frequency, which reduces complexity and resource consumption.

Question 4

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?

AConfigure retrying until a MULERETRY_EXHAUSTED error is raised or the API responds back with a successful response.

BIn Until Successful configuration, set the retry count to 1 for error type HTTP: UNAUTHORIZED.

CPut 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.

DPut 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.

Answer : C

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.

Question 5

Refer to the exhibits.

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?

AOption A

BOption B

COption C

DOption D

EOption E

Answer : E

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). Reference: https://docs.mulesoft.com/apikit/4.x/apikit-4-generate-from-rest-api-task#add-the-api-dependency-to-the-pom-file

Question 6

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?

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.

Create a common-global-error-handler flow in all Mule Applications Refer to it flow-ref wherever needed.

CCreate 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
D.
Create a Mule daman project.
Create a common-global-error-handler flow inside the domain project.
Use this domain project as a dependency.

Answer : C

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. Reference: https://docs.mulesoft.com/mule-runtime/4.3/error-handling#global-error-handler

Question 7

Refer to the exhibit.

What is the result of the Mule Maven Plugin configuration of the value of property its,keystorePassoword in CloudHub 2.0?

ACloudHub encrypts the value

BThe Mule server encrypts the value

CAnypoint Studio secures the value

DRuntime Manager masks the value

Answer : D

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.
