What is the next step to fix this error?

10. What is the correct syntax for a Logger component to output a message with the contents of a 3SON Object payload?

11. Refer to the exhibit.

What expression correctly specifies input parameters to pass the city and state values to the SQL query?

12. Refer to the exhibits.

A web client sends a POST request with the payload {"oid": "1000", "itemid": "AC200", "qty": "4" } to the Mule application. The File Write operation throws a FILE:CONNECTIVITY error.

What response message is returned to the web client?

13. Refer to the exhibits.

The Set Payload transformer's value is set to {'year': '2020'}.

What message value should be added to the Logger component to output the message 'The year is 2020', without hardcoding 2020?

14. Refer to the exhibits.

A Mule application has an HTTP Request that is configured with hardcoded values. To change this, the Mule application is configured to use a properties file named config.yaml.

What valid expression can the HTTP Request host value be set to so that it is no longer hardcoded?

15. A company has an API to manage departments, with each department identified by a unique deptld. The API was built with RAML according to MuleSoft best practices.

What is valid RAML to specify a method to update the details for a specific department?

A)

B)

C)

D)

16. Refer to the exhibit.

In the execution of the Scatter-Gather, the "steep 1 sec" Flow Reference takes about 1 second to complete, and the "sleep 5 sees" Row Reference takes about 5 seconds to complete.

About how many seconds does it take from the time the Scatter-Gather is called until the Set Payload transformer is called?

A)

B)

C)

D)

20. An API implementation has been deployed to CloudHub and now needs to be governed. IT will not allocate additional vCore for a new Mule application to act as an API proxy.

What is the next step to preseive the current vCore usage, but still allow the Mule application to be managed by API Manager?

21. Refer to the exhibits.

A Mule application contains a Choice router.

What is logged when the flow completes?

22. Refer to the exhibit.

The Batch Job processes, filters and aggregates records, What is the expected output from the Logger component?

23. An HTTP Request operation sends an HTTP request with a non-empty JSON object payload to an external HTTP endpoint. The response from the external HTTP endpoint returns an XML body. The result is stored in a target named the Result.

What is the payload at the event processor after the HTTP Request?

24. Refer to the exhibit.

The error occurs when a project is run in Anypoint Studio. The project, which has a dependency that is not in the MuleSoft Maven repository, was created and successfully run on a different computer.

What is the next step to fix the error to get the project to run successfully?

25. Refer to the exhibits.

The two Mule configuration files belong to the same Mule project. Each HTTP Listener is configured with the same host string and the port number, path, and operation values are shown in the display names.

What is the minimum number of global elements that must be defined to support all these HTTP Listeners?

26. Refer to the exhibits.

What is the response to a web client request to http://localhost:8081?

29. A flow needs to combine and return data from two different data sources. It contains a Database SELECT operation followed by an HTTP Request operation.

What is the method to capture both payloads so the payload from the second request does not overwrite that from the first?

30. An On Table Row Database listener retrieves data from a table that contains record_id, an increasing numerical column.

How should the listener be configured so it retrieves new rows at most one time?
