NEW QUESTION # 40
Refer to the exhibits.
Mule application has an HTTP request configuration where host name is hardcoded. Organization is looking to move host and port values to configuration file. What valid expression can be used to so that HTTP configuration can pick the value from configuration file?
- A. #{training.host}
- B. ${training.host}
- C. ${http.host}

NEW QUESTION # 41
Refer to the exhibits.
Each route in the Scatter-Gather sets the payload to the number shown in the label. What response is returned to a web client request to the HTTP Listener?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
Correct answer is as below.
After all processing routes have finished execution, the Scatter-Gather component creates a new Mule event that combines all resulting Mule events from each route, and then passes the new Mule event to the next component in the flow.
{
"0": {
"attributes": ...,
"payload": "100"
},
"1": {
"attributes": ...,
"payload": "200"
}
}

NEW QUESTION # 48
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?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:
In this case three configurations will be required each for port 8000, 6000 and 7000.
There would be three global elements defined for HTTP connections.
Each HTTP connection will have host and port. One example shown below with host as localhost and port 6000
To use an HTTP listener, you need to declare a configuration with a corresponding connection. This declaration establishes the HTTP server that will listen to requests.
Additionally, you can configure a base path that applies to all listeners using the configuration.
<http:listener-config name="HTTP_Listener_config" basePath="api/v1">
<http:listener-connection host="0.0.0.0" port="8081" />
</http:listener-config>

NEW QUESTION # 49
Refer to the exhibits.
A web client submits the request to the HTTP Listener. What response message would be returned to web client?
- A. End
- B. No response would be sent back to client and request will get errored out in Mule
- C. Start
- D. String is not blank
Answer: D
Explanation:
Correct answer is String is not blank.
------------------------------------------------------------------------------------------------------------------------------------------------- Here's specifically what is happening here:
1) Payload is successfully set to "Start"
2) The Is Blank String validator creates an Error Object because the payload is string "Start". Execution stops
#[error.description] = "String is not blank"
3) Because no error handler is defined, the Mule default error handler handles the error. Remember, at its heart, the Mule Default Error handler is an error handling scope with just an on error propagate
4) "String is not blank" is the error message returned to the requestor in the body of the HTTP requestHTTP Status Code: 500 Reference Diagram:
NEW QUESTION # 50
Refer to the exhibit.
How should be the where clause written for the configured input parameters in such a way that it achieves below SQL query?
- A. WHERE city = attributes.city AND state = attributes.state
- B. WHERE city = :city AND state = :state
- C. WHERE city := city AND state := state
- D. WHERE city := ${city} AND state := ${state}
Answer: B
Explanation:
Correct syntax to use where clause is WHERE city = :city AND state = :state This question validates knowledge on using dynamic queries in DB select operation.
Configure Dynamic Queries in the Select Operation
When you need to parameterize not only the WHERE clause but also parts of the query itself (for example, queries that compare tables that depend on a condition, or complex queries for which the project table columns need to vary), you can configure dynamic queries.
In the following example, you configure a dynamic query by using a full expression with a string in which the table depends on a variable $(vars.table). Although some of the query text is dynamic ("SELECT * FROM $(vars.table)), the WHERE clause still defines the WHERE condition using input parameters: in this case, WHERE name = :name.
In your Studio flow, select the Select operation.
In the operation configuration screen, set the SQL Query Text field to SELECT * FROM $(vars.table) WHERE name = :name.
Set the Input Parameters field to {'name' : payload}.
The following screenshot shows the configuration in Studio:
Figure 3. Dynamic query configuration
In the XML editor, the <db:sql> configuration looks like this:
<set-variable variableName="table" value="PLANET"/>
<db:select config-ref="dbConfig">
<db:sql>#["SELECT * FROM $(vars.table) WHERE name = :name"]</db:sql>
<db:input-parameters>
#[{'name' : payload}]
</db:input-parameters>
</db:select>
You can apply input parameters only to parameters in a WHERE clause. To modify any other part of the query, use the DataWeave interpolation operator.

NEW QUESTION # 54
There are three routes configured for Scatter-Gather and incoming event has a payload is an Array of three objects. How routing will take place in this scenario?
- A. Incoming array objects would be split into three and each part would be sent to one route each in sequential manner
- B. Entire event would be sent to each route in parallel
- C. Entire event would be sent to each route sequentially
- D. Incoming array objects would be split into three and each part would be sent to one route each in parallel
Answer: B
Explanation:
Entire event would be sent to each route in parallel.
Scatter-Gather works as follows :
- The Scatter-Gather component receives a Mule event and sends a reference of this Mule event to each processing route.
- Each of the processing routes starts executing in parallel. After all processors inside a route finish processing, the route returns a Mule event, which can be either the same Mule event without modifications or a new Mule event created by the processors in the route as a result of the modifications applied.
- After all processing routes have finished execution, the Scatter-Gather component creates a new Mule event that combines all resulting Mule events from each route, and then passes the new Mule event to the next component in the flow.
NEW QUESTION # 55
A web client sends one GET request to the test flow's HTTP Listener, which causes the test flow to call the updateTemp flow After the test flow returns a response, the web client then sends a different GET request to trie getTemp flow's HTTP Listener The test flow is not called a second time.
What response is returned from the request to the getTemp flow's HTTP Listener?
- A.
- B.
- C.
- D.
Answer: C
NEW QUESTION # 56
Refer to the exhibit.
What is a valid expression for the Choice router's when expression to route events to the documenticShipping flow?
- A. #[ if(payload = 'US') J
- B. #[ payload == 'US' J
- C. #[ if(payload == "US") ]
- D. 0#[ payload = 'US' ]
Answer: B
Explanation:
Choice Router
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.
Properties of <when>
PropertyDescription
Expression (expression)
Expression in DataWeave language to evaluate input.
If the expression evaluates to true, this routing option is used:
<when expression="#[vars.language == 'Spanish']" >
Mulesoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/choice-router-concept With respect to above information , Option 1 is the correct syntax as others are incorrect because of below reasons
* Single = is not the correct syntax to validate the condition. It should be ==
* If keyword is not required in when condition.
