What is the correct syntax for a Logger component to output a message with the contents of a 3SON Object payload?
- A . The payload is: $(payload)
- B . #["The payload is: " ++ payload]
- C . The payload is: #[payload]
- D . #["The payload is: " + payload]
B
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 says payload 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]
Refer to the exhibit.

- A . examples: !include StudentExample.raml
- B . examples: #import StudentExample.raml
- C . examples: !include examples/StudentExample.raml
- D . examples: #import examples/StudentExample.raml
C
Explanation:
To include property. To keep the API definition concise, you can include external content, such as documentation, schemas, and frequently used patterns outside the definition itself. The parser interprets !include as if the content of the externally-hosted file or a URL were declared in-line.
To use the fragments in RAML you have to include the exact path(copy the path) of that fragment you want to use as shown below
Option 3 is the correct as correct syntax is examples: !include examples/StudentExample.raml

How are multiple conditions used in a Choice router to route events?
- A . To route the same event to the matched route of EVERY true condition
- B . To find the FIRST true condition, then distribute the event to the ONE matched route.
- C . None of these
- D . To find the FIRST true condition, then route the same event to the matched route and ALL FOLLOWING routes
B
Explanation:
Choice router finds the FIRST true condition, then distribute the event to the ONE matched route.
MuleSoft Doc
Ref: https://docs.mulesoft.com/mule-runtime/4.1/choice-router-concept The Choice router dynamically routes messages through a flow according to a set of DataWeave expressions that evaluate message content. Each expression is associated with a different routing option. The effect is to add conditional processing to a flow, similar to an if/then/else code block in most programming languages.
Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route’s execution and the others are not checked. If none of the expressions are true, then the default route executes.

What payload is logged at the end of the main flow?
- A . [order1, order2, order3, order4]
- B . [1, 2, 3, 4]
- C . order4
- D . order1order2order3order4
B
Explanation:
This is a trick question. For Each does not modify the current payload. The output payload is the same as the input. Hence output of logger is the same payload which is set before invoking For Each scope. Hence option 2 is correct answer.
What DataWeave expression transforms the example XML input to the CSV output?
A)
B)
C)
D)
- A . Option A
- B . Option B
- C . Option C
- D . Option D
A
Explanation:
Correct answer is as below. Attributes in the incoming xml payload are always accessed using @.Similarly *item is required as we have multiple items in the request %dw 2.0
output application/csv
—
payload.sale.*item map ((value, index) -> {
index: index,
sale: value.@saleId,
itemName: value.desc,
itemPrice: (value.quantity) * (value.price),
