The MCD-Level-1 certification exam is a comprehensive test that covers a wide range of topics related to Mule 4 development. The exam consists of 60 multiple-choice questions that must be completed within 120 minutes. The exam is designed to test the candidate’s understanding of Mule 4 architecture, integration patterns, data transformation, and API design. The exam also covers topics such as MuleSoft API Manager, error handling, and testing.

MuleSoft is a popular integration platform that is used to connect different applications, data sources, and devices. The MuleSoft MCD-Level-1 certification is designed to validate the skills and knowledge of developers who work with Mule 4. This certification is intended for developers who have experience with MuleSoft and want to demonstrate their proficiency in using the platform.

Q45. Refer to the exhibits.

All three of the conditions for the Choice router are true. What messages are written in the application log?

Route1

Route2

Route1,Route2

Route1,Route2,Default

Only one of the routes in the Choice router executes, meaning that the first expression that evaluates to true triggers that route1 execution and the others are not checked. If none of the expressions are true, then the default route executes. Hence only Route1 will be executed as it is the first expression. hence output of logger is Route1.
MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/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.

/accounts/account_type=retail/industry=finance

/accounts?account_type:retail&industry:finance

Correct answer is /accounts?account_type=retail&industry=finance

Q55. A Utlility.dwl is located in a Mule project at src/main/resources/modules. The Utility.dwl file defines a function named encryptString that encrypts a String What is the correct DataWeave to call the encryptString function in a Transform Message component?

1. %dw 2.0
2. output application/json
3. import modules::Utility
4. —
5. Utility::encryptString( “John Smith” )

1. %dw 2.0
2. output application/json
3. import modules::Utility
4. —
5. encryptString( “John Smith” )

1. %dw 2.0
2. output application/json
3. import modules.Utility
4. —
5. encryptString( “John Smith” )

1. %dw 2.0
2. output application/json
3. import modules.Utility
4. —
5. Utility.encryptString( “John Smith” )

Correct answer is
%dw 2.0
output application/json
import modules::Utility
—
Utility::encryptString( “John Smith” )
DataWeave 2.0 functions are packaged in modules. Before you begin, note that DataWeave 2.0 is for Mule 4 apps. For Mule 3 apps, refer to DataWeave Operators in the Mule 3.9 documentation. For other Mule versions, you can use the version selector for the Mule Runtime table of contents.
Functions in the Core (dw::Core) module are imported automatically into your DataWeave scripts. To use other modules, you need to import the module or functions you want to use by adding the import directive to the head of your DataWeave script, for example:
import dw::core::Strings
import camelize, capitalize from dw::core::Strings
import * from dw::core::Strings
The way you import a module impacts the way you need to call its functions from a DataWeave script. If the directive does not list specific functions to import or use * from to import all functions from a function module, you need to specify the module when you call the function from your script. For example, this import directive does not identify any functions to import from the String module, so it calls the pluralize function like this: Strings::pluralize(“box”).
Transform
%dw 2.0
import dw::core::Strings
output application/json
—
{ ‘plural’: Strings::pluralize(“box”) }

Q56. Refer to the exhibits.

The enriched payload in CSV format

An error message

Q57. Refer to the exhibits.

The Set Payload transformer’s value is set to {‘year’: ‘2020’}.

‘#[The year is $(pay load .year)]*

The year is #[payload.year]’

‘#[The year is ” + paytoad.year]’

‘#[“Theyear is++payload-year”]’

Creates and manages discoverable assets to be consumed by line of business developers

Centrally manages partners and consultants to implement line of business projects

Implements line of business projects to enforce common security requirements

Correct answer is Creates and manages discoverable assets to be consumed by line of business developers.

Q60. Refer to the exhibits.

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?

1. {amount=140}
2. {amount=102}
3. {step2amount=100}

1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=40}

1. {amount=140}
2. {amount=102}
3. {step2amount=100}
4. {step2amount=140}

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}

Q61. Refer to the exhibit.
