Objectives for This Validation
There are varied topics targeting the MuleSoft Certified Developer - Level 1 (Mule 4) certificate. They are as follows:
- Structuring Mule Applications
This sector concerns data and it goes ahead to cover tasks such as parameterizing applications, describing and reutilizing global configurations, elements of Flow Reference, private flows, and subflows in breaking an application. Additionally, you will have to identify which data is used between flows and before & after a call. Finally, candidates will have to be proficient in Mule events and resources used for external purposes.
- Transforming Data with DataWeave
This topic goes into the matters of custom data varieties, DataWeave functions and scripts, Mule Flows, and DataWeave syntax. Additionally, candidates will get equipped with such skills as operating with JSON, XML, and Java data chunks as well as their content, and custom data pieces.
- Handling Errors
This section embraces controlling default errors as well as custom global default inaccuracies, stating error handlers, structures for data, and an app mapping of errors. Also, you will have to differentiate between the On Error Continue & On Error Propagate parts and define the Mule Error object.
- Creation and Consumption of APIs
In this domain, candidates will tackle issues with the APIs lifecycle, query parameters, RAML, parameters for URI, and those data types that can be reused. What's more, examinees will be highlighted on samples for format independence, RESTful requests, headers, and nested sources.
- App Network Fundamentals
This area includes such concepts as IT delivery gap, C4E (Center for Enablement), modern API, as well as the HTTP protocol. It is also about capabilities and elements accessible in Anypoint, which also target the API full lifecycle. Apart from these, candidates will get exposed to API connectivity, interface, execution, and invocation alongside application networking facets, requests, and responses.
- Debugging and Troubleshooting Mule Application
It takes care of inspecting Mules, installation of lacking Maven dependencies, and going through and interpreting error alerts from messages for logs related to Mule.

NEW QUESTION # 58
Refer to the exhibits.
A web client submits a request to the HTTP Listener and the HTTP Request throws an error.
What payload and status code are returned to the web client?
Refer to the exhibits. A web client submits a request to the HTTP Listener and the HTTP Request throws an error.
What payload and status code are returned to the web client?
- A. Response body: "Success - End" Default response status code: 200
- B. Response body: "Success - Begin* Default response status code: 200
- C. Error response body: error, description Default error response status code: 500
- D. Response body: "Error" Default response status code: 200
Answer: D
Explanation:
Response body: "Error" Default response status code: 200.
-------------------------------------------------------------------------------------------------------------------------------------------------
1) Payload is successfully set to "Success - Started Flow"
2) When HTTP Request throws an error, execution halts
#[error.description] = "ABC"
#[error.errorType] = "XYZ"
3) The On Error Continue scope handles the error. When On Error Continue scope is invoked, all the processors in error block are executed and success response is sent back to the client with payload which is set in error flow. In this case payload is set to "Error" value in error block.
4) "Error" is returned to the requestor in the body of the HTTP request with HTTP Status Code: 200 as On error continue always sends success error code.

Mule application is run in Anypoint Studio.
If the mule application starts correctly, what URI and port numbers can receive web client requests? If the mule applications fails to start , what is the reason for the failure?
- A. The mule application start successfully
Web client requests can only be received at URI on port 2222 but not on port 3333 - B. The mule application fails to start
There is URL path conflict because both HTTP Listeners are configured with same path - C. The mule application start successfully
Web client requests can be received at URI on port 2222 and on port 3333. - D. The mule application fails to start because of the port binding conflict as HTTP request also use same port i.e. 3333

The Batch Job scope contains two Batch Steps scopes with different accept expression.
The input payload is passed to the Batch Job scope.
After the entire payload is processed by the batch job scope , what messages have been logged by the Logger component?
- A. 1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=140} - B. 1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=140} - C. 1. {amount=140}
2. {amount=102}
3. {step2amount=100} - D. 1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=40}
Answer: B
Explanation:
5. {step2amount=102}
Explanation:
Lets understand this solution step by step.
1) Batch Step (Less than 50)
Accept expression for this batch step is less than 50. Hence elements which will go in this batch step are amount value 40 and 2. Hence output of logger in first batch step is
{amount=140}
{amount=102}
2) Batch Step (Greater than 20)
Accept condition for this batch step is greater than 20. Note that input amount values for this batch step are 100 , 140 and 102 (last two values have been updated in batch step less than 50) As all values satisfy this condition out put of second logger is
{step2amount=100}
{step2amount=140}
{step2amount=102}
Hence correct answer to this question is
{amount=140}
{amount=102}
{step2amount=100}
{step2amount=140}
{step2amount=102}
