Refer to the exhibits. The main flow contains an HTTP Request operation configured to call the child flow's HTTP Listener.

Aweb client sends a GET request to the HTTP Listener with the sty query parameter set to 30.

After the HTTP Request operation completes, what parts of the Mule event at the main flow's Logger component are the same as the Mule event that was input to theHTTP Request operation?

The payload and all variables

All variables

The entire Mule event

The payload and all attributes

Question # 12

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?

Change the method attribute value to "*â€™â€™

Change the path attribute value to "/api/ship"

Change the allowed method attributes value to "POST"

Change the protocol attribute value to "HTTPS"

Question # 13

What is the correct syntax to define and call a function in Database?

Option A

Option B

Option C

Option D

Explanation:

Keyword to ad function in Dataweave transformation is fun. Hence option 2 and 4 are invalid. Also parameters needs to be passed exactly in same order as defined in function definition. Hence correct answer is'

fun addKV( object: Object, key: String, value: Any) =

object ++ {(key):(value)}

---

addKV ( {"hello': "world"}, "hola", "mundo" )

DataWeave FunctionDefinition Syntax

To define a function in DataWeave use the following syntax:

fun myFunction(param1, param2, ...) =

The fun keyword starts the definition of a function.

myFunction is the name you define for the function.

Function namesmust be valid identifiers.

(param1, param2, â€¦ , paramn) represents the parameters that your function accepts.

You can specify from zero to any number of parameters, separated by commas (,) and enclosed in parentheses.

The = sign marks the beginning of thecode block to execute when the function is called.

represents the actual code that you define for your function.

Returns an array that is the result of applying a transformation function (lambda) to each of the elements.
MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/dataweave-cookbook-map 
Themap operator is a function in Dataweave which iterates over the items in an array and outputs them into a new array. It basically accepts input as a list of items in an array and manipulates the items in the array in order to form a new array as an output.

A web client sends a GET request to the HTTP Listener.
What response message is returned to the web client?

									Explanation:
								
								
									
1. SetPayload â€œStartâ€
2. 'Is Balnk String' Creates an Error object with #[error.description] =â€œString is not blankâ€
3. Default Error Handler catches and Propagates error
4. 'On Error Propogate' is 'RED IN RED OUT'. It Returns Status Code : 500 & #[error.description]
--------------------------------------------------------------------------------------------------------------------------
Correct answer isÂ String is not blank.Â Because validation component will throw an error as payload is not blank.

									Explanation:
								
								
									
Paths
The pathof an HTTP listener can be static, which requires exact matches, or feature placeholders. Placeholders can be wildcards (*), which match against anything they are compared to, or parameters ({param}), which not only match against anything but also capturethose values on a URI parameters map.
Take the following example paths for three listeners using a configuration that establishesÂ api/v1Â as the base path:
account/mulesoft/main-contact: only match the exact path requestÂ http://awesome-company.com/api/v1/account/mulesoft/main-contact 
account/{accountId}/main-contact: matches all path requests structured similarly, such asÂ http://awesome-company.com/api/v1/account/salesforce/main-contact , and saveÂ salesforceÂ as the value ofÂ accountId.
account/{accountId}/*: matches all path requests different fromÂ main-contact, such asÂ http://awesome-company.com/api/v1/account/mulesoft/users , and saveÂ mulesoftÂ as the value ofÂ accountId.

									Explanation:
								
								
									
Scatter-Gather Router
The Scatter-Gather component is arouting 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.

										Question # 20									
								
							
							
								
									
										A Database On Table Row listener retrieves data from a CUSTOMER table that contains a primary key userjd column and an increasing kxjin_date_time column. Neither column allows duplicate values.
How should the listener be configured so it retrieves each row at most one time?
									

									
										A. Set the watermark column to the bgin_date_time column
										B. Set the target value to the last retrieved login_date_time value
										C. Set the target value to thelast retrieved user_jd value
										D. Set the watermark column to the user_Id column
																																							

					

						
						

						
							
								
									The Answer Is: 
									A
								
								
																		Good news! This question has an explanation. Do you want to see it?


									
																	
							
						
						

						
														
								
									Explanation:
								
								
									
* Watermark allows the poll scope to poll for new resources instead of getting the same resource over and over again.
* The database table must be ordered so that theâ€œwatermark functionalityâ€ can move effectively in the ordered list. Watermark stores the current/last picked up â€œrecord id.â€
* If the Mule application is shut down, it will store the last picked up â€œrecord idâ€ in the Java Object Store and the data will continue to exist in the file. This watermark functionality is valuable and enables developers to have increased transparency.
* Developers do not need to create code to handle caching; it is all configurable!
* There are two columns and both are unique butuser_id can't guaranty sequence whereas date_time will always be in increasing order and table content can easily be ordered on the basis of last processed date_time.
So correct answer is: Set the watermark column to the date_time column
