Question No. 1

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?

AEnable the auto-generate CorrelationID option when scaffolding the flow

BEnable the CorrelationID checkbox in the HTTP Listener configuration

CConfigure a custom correlation policy

DNO action is needed as the correlation ID is returned to the caller in the response header by default

Show Answer

Correct Answer: D

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.

Question No. 2

Refer to the exhibit.

What action must be performed to log all the errors raised by the VM Connector?

AAdd <AsyncLOgger name='orgroute.extensions vm' level=ERROR'I> inside the Logger tag

BAdd <AsyncLOgger name='orgroute.extensions vm' level=ERROR'/> inside the Appenders tag

CConfigure <Logger level-'ERROR'/> inside the VM Connector configuration

DNothing, as error-level events are automatically logged

Show Answer

Correct Answer: B

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.

Question No. 3

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?

AInitialize, validate, compute, test, package, verify, install, deploy

BValidate, initialize, compile, package, test, install, verify, verify, deploy

CValidate, initialize, compile, test package, verify, install, deploy

DValidation, initialize, compile, test, package, install verify, deploy

Show Answer

Correct Answer: C

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.

Question No. 4

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

Show Answer

Correct 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.
