NEW QUESTION # 146
What is the correct syntax for a Logger component to output a message with the contents of a 3SON Object payload?
Answer: A
Explanation:
Option 3 is the only corect answer as it concatenates payload with String.
Below option wont work.
#["The payload is " ++ payload]
Concatenation function expects both arguments to be string. As the question sayspayload is json object , this will throw error while running it. You can try this in Anypoint Studio and you will get the same result which I mentioned.
hence correct answer is
The payload is: #[payload]
NEW QUESTION # 147
Refer to the exhibit.
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?
Answer: C
Explanation:
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 answeris
lookup( "createCustomerObject", {first: "Aice, last: "Green"})

NEW QUESTION # 148
Which of the below activity doesn't support parallel execution?
Answer: C
Explanation:
The First Successful router iterates through a list of configured processing routes until one of the routes executessuccessfully. This is sequential execution. In all other options mentioned in the question ,we can achieve parallel execution.
NEW QUESTION # 149
Refer to the exhibits. A database Address table contains a ZIPCODE column and an increasing ID column.
The Address table currently contains tour (4) records. The On Table Row Database listener is configured with its watermark set to the Address table's ZIPCODE column and then the Mule application is run in Anypoint Studio tor the first time, and the On Table Row Database listener polls the Address table.
Anew row is added to the database with 1D=5 and ZIPCODE-90006, and then the On Table Row Database listener polls the database again.
Alter the next execution of the On Table Row Database listener polling, what database rows have beenprocessed by the Mule flow since the Mule application was started?
Answer: C
NEW QUESTION # 150
Refer to the exhibits.
The Validation component in theTry 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?
Answer: A
Explanation:
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 scopewhich 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 Referencecalls 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 OnError 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.
