質問 # 90
Refer to the exhibits.

A web client submits the request to the HTTP Listener. What response message would be returned to web client?

A. String is not blank
B. End
C. Start
D. No response would be sent back to client and request will get errored out in Mule

正解：A

解説：
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:

質問 # 93
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?

A. 1. %dw 2.0
2. output application/json
3. import modules::Utility
4. ---
5. encryptString( "John Smith" )
B. 1. %dw 2.0
2. output application/json
3. import modules::Utility
4. ---
5. Utility::encryptString( "John Smith" )
C. 1. %dw 2.0
2. output application/json
3. import modules.Utility
4. ---
5. Utility.encryptString( "John Smith" )
D. 1. %dw 2.0
2. output application/json
3. import modules.Utility
4. ---
5. encryptString( "John Smith" )

正解：A

解説：
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") }

質問 # 95
An SLA based policy has been enabled in API Manager. What is the next step to configure the API proxy to enforce the new SLA policy?

A. Add new environment variables and restart the API proxy
B. Add new property placeholders and redeploy the API proxy
C. Restart the API proxy to clear the API policy cache
D. Add required headers to the RAML specification and redeploy the new API proxy

正解：D

解説：
Correct answer is Add required headers to RAML specification and redeploy new API proxy MuleSoft Doc Ref : https://docs.mulesoft.com/api-manager/2.x/tutorial-manage-an-api Steps are as below :
Add the Required RAML Snippet
SLA-based rate limiting requires adding a RAML or OAS snippet to your API. This procedure demonstrates adding a RAML snippet.
Specify the client ID and secret as query parameters.
Add a section called traits: at the RAML root level to define query parameters:
traits:
- client-id-required:
queryParameters:
client_id:
type: string
client_secret:
type: string
Add the client-id-required trait to every method that requires these query parameters:
/users:
get:
is: [client-id-required]
description: Gets a list of JSONPlaceholder users.
Step 2 : Add the SLA Tier in API Manager
Step 3 : Apply the policy and redeploy

質問 # 97
Where is metadata stored in a Mule project

A. Global Element
B. Config.yaml file
C. application-types.xml
D. POM.xml file

正解：C

解説：
Metadata is stored in application-types.xml flle located under src/main/resources.
Mule 4 applications contain an application-types.xml file, which is where metadata around your data types is stored. For example, if you create a new CSV type, that metadata will be added to this file. This new file is easy to share, commit, and merge when conflicts arise, which enables you to do more metadata-driven development.
MuleSoft Doc Ref : https://docs.mulesoft.com/mule-runtime/4.3/intro-studio#metadata-storage

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

A. Route2
B. Route1,Route2,Default
C. Route1,Route2
D. Route1

正解：D

解説：
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.
