質問 # 127
Refer to the exhibits. Client sends the request to ClientRequestFlow which calls ShippingFlow using HTTP Request activity.
During E2E testing it is found that that HTTP:METHOD_NOT_ALLOWED error is thrown whenever client sends request to this flow.
What attribute you would change in ClientRequestFlow to make this implementation work successfully?

A. Change the allowed method attributes value to "POST"
B. Change the method attribute value to "*''
C. Change the protocol attribute value to "HTTPS"
D. Change the path attribute value to "/api/ship"

正解：A

解説：
Correct answer is Change the method attributes value to "POST".
It can be fixed in either of the two ways as below.
1) Changing method attribute to POST in ClientRequestFlow
2) Setting allowedMethods as PUT in ShippingFlow (but doesn't fit as question mentions about changing ClientRequestFlow)

For such questions always look for Syntax:
I call it "Wrap the Map"
trains:
{(
When mapping array elements (JSON or JAVA) to XML, wrap the map operations in {(..)}
-{ } are defining the object
-( ) are transforming each element in the array as a key/value pair

質問 # 129
Refer to the exhibits.

The web client sends a POST request to the ACME Order API with an XML payload. An error is returned.
What should be changed in the request so that a success response code is returned to the web client?

A. Set a response header with the name Content-Type to a value of applkation/xml
B. Set a response header with the name Content-Type to a value of application/octet-stream
C. Set a request header with the name Content-Type to a value of applicatron/octet-stream
D. Set a request header with the name Content-Type to a value of application/xml

正解：D

解説：
The HTTP 415 Unsupported Media Type client error response code indicates that the server refuses to accept the request because the payload format is in an unsupported format. The format problem might be due to the request's indicated Content-Type or Content-Encoding , or as a result of inspecting the data directly. As per RAML input is expected in application/xml.
Hence correct answer is Set a request header with the name Content-Type to a

質問 # 130

D. The database response

正解：A

質問 # 132
Refer to the exhibits.

The Validation component in the Try scope throws an error.
What response message is returned to a client request to the main flow's HTTP Listener?
The Validation component in the Try scope throws an error. What response message is returned to a client request to the main flow's HTTP Listener?

A. Success - main flow
B. Error - Try scope
C. Validation Error
D. Error - main flow

正解：A

解説：
Note that private flow has error scope defined as On Error Continue . So when error occurs in private flow , it is handled by this On Error Continue scope which sends success response back to main flow and does not throw back an error. So main continues normally and payload is set to Success - main flow.
Hence correct answer is Success - main flow
1) HTTP listener received request
2) The Flow Reference calls the child flow
3) The Is Number validator creates an Error Object because the payload isn't an integer. Child Flow execution stops
#[error.description] = "payload is not a valid INTEGER value"
#[error.errorType] = VALIDATION:INVALID_NUMBER
4) The On Error Continue handles the errorThe payload is set to "Error - Sub Flow"
5) "Error - Sub Flow" is returned to the main flow as if the child flow was a success. The Set Payload is executed. The payload is reset to "Success - Finished Main Flow"
6) "Success - Main Flow" is returned to the requestor in the body of the HTTP request. HTTP Status Code: 200 As you can see, in the above example, because the error was caught by an On Error Continue scope in the child flow (RED in, GREEN out) when the Mule Message returns to the parent flow, the parent flow knows none-the-different that there was a failure because the on error continue returns a 200 success message. Note that because, to the mainFlow, the childFlow appeared to succeed, the processing of mainFlow resumed after the flow reference.

質問 # 133
A mule project contains MySQL database dependency . The project is exported from Anypoint Studio so that it can be deployed to Cloudhub. What export options needs to be selected to create the smallest deployable archive that will successfully deploy to Cloudhub?

A. Select only below option 2) Include project module and dependencies
B. No need to select any of the below options 1) Attach project sources 2) Include project module and dependencies
C. Select both the options 1) Attach project sources 2) Include project module and dependencies
D. Select only below option 1) Attach project sources

正解：A

解説：
You can choose Attach Project Sources to include metadata that Studio requires to reimport the deployable file as an open Mule project into your workspace. You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace. But requirement here is to create smallest deployable archive that will successfully deploy to Cloudhub. Hence we can ignore this option.
We need to select Include project module and dependencies
As actual modules and external dependencies required to run the Mule application in a Mule runtime engine Hence correct answer is Select only below option 2) Include project module and dependencies MuleSoft Doc Ref : https://docs.mulesoft.com/studio/7.5/import-export-packages#exporting-a-studio-project-to-a-deployable-mule-application

質問 # 134
Refer to the exhibits. A web client submits a request to http://localhost:8081/fliqhts?destination=SFO and the Web Service Consumer throws a WSC:BAD_REQUEST error.
What is the next step to fix this error?

A. set a SOAP payload before the Consume operation that contains the destination query parameter
B. set a JSON payload before the Consume operation that contains the destination query parameter
C. set a property m the Consume operation equal to the destination query parameter
D. Set a header In the Consume operation equal to the destination query parameter

正解：A

解説：
As can be seen in error message , SOAP service findFlights expects the SOAP paylaod. This can be set using transform message processor which forms SOAP payload before the Consume operation that contains the destination query parameter

What is the correct DataWeave expression for the Set Payload transformer to call the createCustomerObject flow with values for the first and last names of a new customer?

A. lookupf "createCustomerObject", { first: "Alice", last: "Green" > )
B. lookupC createCustomerObJect( "Alice", "Green- ) )
C. createCustomerObject( "Alice", "Green")
D. createCustomerObject( { first: "Alice", last: "Green" > )

正解：A

解説：
lookup(String, Any, Number)
This function enables you to execute a flow within a Mule app and retrieve the resulting payload.
It works in Mule apps that are running on Mule Runtime version 4.1.4 and later.
Similar to the Flow Reference component (recommended), the lookup function enables you to execute another flow within your app and to retrieve the resulting payload. It takes the flow's name and an input payload as parameters. For example, lookup("anotherFlow", payload) executes a flow named anotherFlow.
Correct answer is
lookup( "createCustomerObject", {first: "Aice, last: "Green"})

質問 # 147
Refer to the exhibits.

A web client submits a request to http://localhQst:8081. What is the structure of the payload at the end of the flow?

正解：C

解説：
Scatter-Gather Router
The Scatter-Gather component is a routing event processor that processes a Mule event through different parallel processing routes that contain different event processors. Each route receives a reference to the Mule event and executes a sequence of one or more event processors. Each of these routes uses a separate thread to execute the event processors, and the resulting Mule event can be either the same Mule event without modifications or a new Mule event with its own payload, attributes, and variables. The Scatter-Gather component then combines the Mule events returned by each processing route into a new Mule event that is passed to the next event processor only after every route completes successfully.
The Scatter-Gather component executes each route in parallel, not sequentially. Parallel execution of routes can greatly increase the efficiency of your Mule application and may provide more information than sequential processing.
