NEW QUESTION # 115
Refer to the exhibit. The main flow contains an HTTP Request in the middle of the flow. The HTTP Listeners and HTTP request use default configurations.
What values are accessible to the Logger at the end of the flow after a web client submit request to http://local:801/order?color=red?

A. payload quantity var
B. payload color query param
C. payload quantity var color query param
D. payload

Answer: A

Explanation:
In this case as outbound call is made using HTTP: POST /child , all attributes will be replaced by this invocation. Hence query parameter will not be accessible at logger.

NEW QUESTION # 116
A Scatter-Gather processes three separate HTTP requests. Each request returns a Mule event with a JSON payload. What is the final output of the Scatter-Gather?

A. An Object containing all three Mule event Objects
B. An Object containing all three JSON payload Objects
C. An Array of the three JSON payload Objects
D. An Array of the three Mule event Objects

Answer: A

Explanation:
Correct answer is An Object containing all three Mule event Objects
The Scatter-Gather component is a routing 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.
Sample output is as below

NEW QUESTION # 118
Refer to the exhibits.

A. [''D", "E"]
B. [ "A", "C, "D", "E" ]
C. [''E'']
D. [ ["A", "C", "D" ], ["E"] ]

Answer: C

Explanation:
Logs would look like:

NEW QUESTION # 121
Refer to the exhibits.

What is the response when a client submits a request to http://localhost:8081?

A. Before
B. null
C. Validation error
D. After

Answer: C

Explanation:
----------------------------------------------------------------------------------------------------------------------------------- Here's specifically what is happening here:
1) Payload is successfully set to "Before"
2) Is null validation is used which will pass the message only if payload is null. In this case as payload is not null, it creates an Error Object. Flow execution stops
#[error.description] = "Validation error"
3) Because no error handler is defined, the Mule default error handler handles the error
4) "Validation error" is the error message returned to the requestor in the body of the HTTP request with HTTP Status Code: 500 Reference diagram:

NEW QUESTION # 122
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 - Begin* Default response status code: 200
B. Error response body: error, description Default error response status code: 500
C. Response body: "Error" Default response status code: 200
D. Response body: "Success - End" Default response status code: 200

Answer: C

Explanation:
Correct Answer: 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.

NEW QUESTION # 123
Refer to the exhibit.

What can be added to the flow to persist data across different flow executions?

A. Key/value pairs in the ObjectStore
B. session variables
C. properties of the Mule runtime app object
D. Properties of the Mule runtime flow object

Answer: A

Explanation:
An object store is a facility for storing objects in or across Mule applications. Mule runtime engine (Mule) uses object stores to persist data for eventual retrieval. Internally, Mule uses object stores in various filters, routers, and other message processors that need to store states between messages.
Object stores are available in all deployment targets. If you deploy your application to CloudHub, you can also use Object Store V2.
Correct answer is Key/value pair in Object store

NEW QUESTION # 127
Which Mule component provides a real-time, graphical representation of the APIs and mule applications that are running and discoverable?

A. Runtime Manager
B. Anypoint Visualizer
C. API Notebook
D. API Manager

Answer: B

Explanation:
Correct answer is Anypoint Visualizer
MuleSoft Doc Ref : https://docs.mulesoft.com/visualizer/
Anypoint Visualizer provides a real-time, graphical representation of the APIs, and Mule applications that are running and discoverable. It also displays third-party systems that are invoked by a Mule API, proxy, or application within your application network. The data displayed in the graph is dynamically updated and does not require prior configuration. Additionally, the data displayed is secure, as only users with the proper permissions can view the application network graph.

NEW QUESTION # 128
An API instance of type API endpoint with API proxy is created in API manager using an API specification from Anypoint Exchange. The API instance is also configured with an API proxy that is deployed and running in CloudHub.
An SLA- based policy is enabled in API manager for this API instance.
Where can an external API consumer obtain a valid client ID and client secret to successfully send requests to the API proxy?

A. In Anypoint Studio, from components generated by Rest Connect for API specification
B. In Runtime Manager, from the properties tab of the deployed approved API proxy
C. In the organization's public API portal in Anypoint Exchange, from an approved client application for the API proxy
D. In Anypoint Studio, from components generated by APIkit for the API specification

Answer: C

Explanation:
* When a client application is registered in Anypoint Platform, a pair of credentials consisting of a client ID and client secret is generated.
* When the client application requests access to an API, a contract is created between the application and that API.
* An API that is protected with a Client ID Enforcement policy is accessible only to applications that have an approved contract.

NEW QUESTION # 131
A mule project contains MySQL database dependency . The project is exported from Anypoint Studio so that it can be deployed to Cloudhub. What export options needs to be selected to create the smallest deployable archive that will successfully deploy to Cloudhub?

A. Select both the options 1) Attach project sources 2) Include project module and dependencies
B. Select only below option 1) Attach project sources
C. Select only below option 2) Include project module and dependencies
D. No need to select any of the below options 1) Attach project sources 2) Include project module and dependencies

Answer: C

Explanation:
You can choose Attach Project Sources to include metadata that Studio requires to reimport the deployable file as an open Mule project into your workspace. You must keep the Attach Project Sources option selected to be able to import the packaged JAR file back into a Studio workspace. But requirement here is to create smallest deployable archive that will successfully deploy to Cloudhub. Hence we can ignore this option.
We need to select Include project module and dependencies
As actual modules and external dependencies required to run the Mule application in a Mule runtime engine Hence correct answer is Select only below option 2) Include project module and dependencies MuleSoft Doc Ref : https://docs.mulesoft.com/studio/7.5/import-export-packages#exporting-a-studio-project-to-a-deployable-mule-application
