Salesforce Certified MuleSoft Developer II Practice Test - Questions Answers, Page 4
List of questions
Question 31

Which plugin or dependency is required to unit test modules created with XML SDK?
Explanation:
To unit test modules created with XML SDK, the developer needs to use the MUnit Extensions Maven plugin. This plugin allows testing XML SDK modules using MUnit by adding a dependency to the module under test and using a custom processor tag to invoke it.

Question 32

Which statement is true when working with correlation IDS?
Explanation:
When working with correlation IDs, the HTTP Listener generates correlation IDs unless a correlation ID is received in the HTTP request. In that case, it propagates the received correlation ID throughout the flow execution. Correlation IDs are used to track events across different flows or applications.

Question 33

Refer to the exhibit.
What is the result of the Mule Maven Plugin configuration of the value of property its,keystorePassoword in CloudHub 2.0?
Explanation:
The result of the Mule Maven Plugin configuration of the value of property its,keystorePassword in CloudHub 2.0 is that Runtime Manager masks the value. This means that Runtime Manager hides or obscures the value from anyone who views it in Runtime Manager or Anypoint Platform.

Question 34

An organization uses CloudHub to deploy all of its applications.
How can a common-global-handler flow be configured so that it can be reused across all of the organization's deployed applications?
Explanation:
To configure a common-global-handler flow that can be reused across all of the organization's deployed applications, the developer should create a Mule Plugin project, create a common-global-error-handler flow inside the plugin project, and use this plugin as a dependency in all Mule applications. This way, the developer can import the common-global-error-handler flow in any application that needs it and avoid duplicating the error handling logic.
Reference: https://docs.mulesoft.com/mule-runtime/4.3/error-handling#global-error-handler
Question 35

A Mule API receives a JSON payload and updates the target system with the payload. The developer uses JSON schemas to ensure the data is valid.
How can the data be validation before posting to the target system?
Explanation:
To validate the data before posting to the target system, the developer should add the JSON module dependency and add the validate-schema operation in the flow, configured to reference the schema. The JSON module provides a validate-schema operation that validates a JSON payload against a JSON schema and throws an error if the payload is invalid.
Reference: https://docs.mulesoft.com/json-module/1.1/json-validate-schema
Question 36

Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?
Explanation:
To invoke multiple HTTP APIs in parallel and roll back failed requests in sequence, the developer should use a Scatter-Gather router as a central Saga orchestrator for all API requests with compensating actions for failing routes. A Scatter-Gather router executes multiple routes concurrently and aggregates the results. A Saga orchestrator coordinates a series of actions across different services and handles failures by executing compensating actions. Therefore, using a Scatter-Gather router as a Saga orchestrator allows invoking multiple HTTP APIs in parallel and rolling back any failed requests in sequence.

Question 37

Which properties are mandatory on the HTTP Connector configuration in order to use the OAuth 2.0 Authorization Code grant type for authentication?
Explanation:
To use the OAuth 2.0 Authorization Code grant type for authentication, the HTTP Connector configuration requires the following properties: token URL, authorization URL, client ID, client secret, and local callback URL. The token URL is the endpoint of the authorization server that provides access tokens. The authorization URL is the endpoint of the authorization server that initiates the user consent flow. The client ID and client secret are the credentials of the Mule application registered with the authorization server. The local callback URL is the endpoint of the Mule application that receives the authorization code from the authorization server.

Question 38

An order processing system is composed of multiple Mule application responsible for warehouse, sales and shipping. Each application communication using Anypoint MQ. Each message must be correlated against the original order ID for observability and tracing.
How should a developer propagate the order ID as the correlation ID across each message?
Explanation:
To propagate the order ID as the correlation ID across each message using Anypoint MQ, the developer should wrap all Anypoint MQ Publish operations within a With CorrelationID scope from the Tracing module, setting the correlation ID to the order ID. The With CorrelationID scope allows setting a custom correlation ID for any event that occurs within it. The Tracing module also enables distributed tracing across different Mule applications and services using Anypoint Monitoring.
Reference: https://docs.mulesoft.com/tracing-module/1.0/tracing-module-reference#with-correlation-id-scope https://docs.mulesoft.com/tracing-module/1.0/tracing-module-concepts
Question 39

A Mule application for processing orders must log the order ID for every log message output.
What is a best practice to enrich every log message with the order ID?
Explanation:
To enrich every log message with the order ID, the developer should use the Tracing module to set logging variables with a Mapped Diagnostic Context (MDC). The Tracing module allows adding custom key-value pairs to log messages using MDC variables. The developer can use Set Logging Variables operation to set the order ID as an MDC variable and then use it in any logger processor within the same thread or event.
Reference: https://docs.mulesoft.com/tracing-module/1.0/tracing-module-reference#set-logging-variables
Question 40

Refer to the exhibit.
What is the result if ''Insecure'' selected as part of the HTTP Listener configuration?
Explanation:
Based on the exhibit below, if 'Insecure' is selected as part of the HTTP Listener configuration, the HTTP listener will only accept HTTP requests. This means that no TLS context will be configured for this listener and no encryption or authentication will be applied to incoming requests. The protocol attribute of this listener will be set to HTTP instead of HTTPS.
