Salesforce Certified MuleSoft Developer II Sample Questions (Q46-Q51):

NEW QUESTION # 46
Refer to the exhibit.

The flow name is ''implementation'' with code for the MUnit test case.
When the MUnit test case is executed, what is the expected result?

A. The test throws an error and does not start
B. The test case fails with an assertion error
C. The test case fails with an unexpected error type
D. The test case passes

Answer: B

Explanation:
Based on the code snippet and MUnit test case below, when the MUnit test case is executed, the expected result is that the test case fails with an assertion error. This is because the assert-equals processor compares two values for equality, and fails if they are not equal. In this case, the expected value is 'Hello World', but the actual value returned by the implementation flow is 'Hello Mule'. Therefore, the assertion fails and an error is thrown. Reference: https://docs.mulesoft.com/munit/2.3/assert-equals-processor

NEW QUESTION # 47
A healthcare portal needs to validate the token that it sends to a Mule API. The developer plans to implement a custom policy using the HTTP Policy Transform Extension to match the token received in the header from the heathcare portal.
Which files does the developer need to create in order to package the custom policy?

A. Deployable ZIP file, YAML configuration file
B. JSON properties file, XML template file
C. JSON properties file, YAML configuration file
D. XML template file, YAML configuration file

Answer: D

Explanation:
To package a custom policy using the HTTP Policy Transform Extension, the developer needs to create an XML template file and a YAML configuration file. The XML template file defines the policy logic using Mule components and placeholders for user-defined properties. The YAML configuration file defines the metadata of the policy, such as its name, description, category, parameters, and dependencies. Reference: https://docs.mulesoft.com/api-manager/2.x/http-policy-transform#packaging-the-policy

NEW QUESTION # 48
A company with MuleSoft Titanium develops a Salesforce System API using MuleSoft out-of-the-box Salesforce Connector and deploys the API to CloudHub.
Which steps provide the average number of requests and average response time of the Salesforce Connector?

A. Access Anypoint Monitoring's built-in dashboard. Select a resource.
Locate the information under the Connectors tab.
B. Change the API Implementation to capture the information in the log.
Retrieve the information from the log file.
C. Access Anypoint Monitoring's built-in dashboard
Seclect a resource.
Create a custom dashboard to retrieve the information.
D. Access Anypoint Monitoring built-in dashboard.
Select a resource.
Locate the information under Log Manager < Raw Data.

Answer: A

Explanation:
To get the average number of requests and average response time of the Salesforce Connector, the developer should access Anypoint Monitoring's built-in dashboard, select a resource (such as an application or an API), and locate the information under the Connectors tab. The Connectors tab shows metrics for each connector used by the resource, such as average requests per minute, average response time, and failures. Reference: https://docs.mulesoft.com/monitoring/built-in-dashboard-reference

NEW QUESTION # 49
Two APIs are deployed to a two-node on-prem cluster. Due to a requirements change, the two APIs must communicate to exchange data asynchronously.

A. Instead of using the VM Connector use <flow-ref>directly
B. It is not possible to use the VM Connector since the APIs are running in a cluster mode and each mode has it own set of VM Queues
C. The VM Connector is used to inter-application communication, so it is not possible to use the VM Connector
D. If the two APIs use the same domain, the VM Connector can be leveraged

Answer: D

Explanation:
To communicate asynchronously between two APIs deployed to a two-node on-prem cluster, the developer can use the VM Connector if the two APIs use the same domain. The VM Connector allows passing messages between different Mule applications within a single Mule runtime instance or across different instances using shared memory or persistent storage. If two APIs are deployed under the same domain, they can share resources such as VM queues and communicate asynchronously using VM Connector operations.

NEW QUESTION # 50
Refer to the exhibit.
What required changes can be made to give a partial successful response in case the United Airlines API returns with a timeout?

A. Add a Scatter-Gather component inside a Try scope.
Set the payload to a default value 'Error'' inside the error handler using the On Error Continue scope.
B. Add Flow Reference components inside a Try scope
Set the payload to a default value '' inside the error handler using the On Error Propagate scope
C. Add Flow Reference components inside a Try scope.
Set the payload to a default value'' insider the error handler using the ON Error Continue scope
D. Add a Scatter-gather component inside a Try scope.
Set the payload to a default value 'Error' inside the error handler using the On Error Propagate scope.

Answer: A

Explanation:
To give a partial successful response in case the United Airlines API returns with a timeout, the developer should add a Scatter-Gather component inside a Try scope, and set the payload to a default value 'Error' inside the error handler using the On Error Continue scope. A Scatter-Gather component allows sending multiple requests concurrently and aggregating the responses into an array. A Try scope allows handling errors that occur within it using an error handler. An On Error Continue scope allows continuing the flow execution after handling an error. Therefore, by using these components, the developer can send requests to both APIs in parallel, handle any timeout errors from United Airlines API, and return a partial response with a default value for that API. Reference: https://docs.mulesoft.com/mule-runtime/4.3/scatter-gather-concept https://docs.mulesoft.com/mule-runtime/4.3/try-scope-concept https://docs.mulesoft.com/mule-runtime/4.3/on-error-continue-concept
