Salesforce SALESFORCE-MULESOFT-DEVELOPER-II Online Questions & Answers

• Question 31:

  A Mule application need to invoice an API hosted by an external system to initiate a process. The external API takes anywhere between one minute and 24 hours to compute its process. Which implementation should be used to get response data from the external API after it completes processing?

  A. Use an HTTP Connector to invoke the API and wait for a response
  B. Use a Scheduler to check for a response every minute
  C. Use an HTTP Connector inside Async scope to invoice the API and wait for a response
  D. Expose an HTTP callback API in Mule and register it with the external system
  D. Expose an HTTP callback API in Mule and register it with the external system

  ---

  Explanation/Reference:

  To get response data from the external API after it completes processing, the developer should expose an HTTP callback API in Mule and register it with the external system. This way, the external API can invoke the callback API with the

  response data when it is ready, instead of making the Mule application wait for a long time or poll for a response repeatedly.

• Question 32:

  Refer to the exhibit.

  

  A developer generates the base scaffolding for an API in Anypoint Studio. Which HTTP status code is returned while testing using the API Kit console if no values are entered in client-secret?

  A. HTTP status code:200
  B. HTTP status code:403
  C. HTTP status code:400
  D. HTTP status code:500
  B. HTTP status code:403

  ---

  Explanation/Reference:

  Based on the code snippet and schema.json file below, when testing using the API Kit console if no values are entered in client-secret, HTTP status code 403 (FORBIDDEN) is returned. This is because client-secret is defined as a required header parameter in schema.json file, which means that it must be present in every request. If no values are entered in client-secret, then it is equivalent to omitting this header parameter, which violates the schema and causes APIKit Router to return HTTP status code 403. https://docs.mulesoft.com/ apikit.x/apikit-4-headers

• Question 33:

  What is the MuleSoft recommended method to encrypt sensitive property data?

  A. The encryption key and sensitive data should be different for each environment
  B. The encryption key should be identical for all environments
  C. The encryption key should be identical for all environments and the sensitive data should be different for each environment
  D. The encryption key should be different for each environment and the sensitive data should be the same for all environments
  A. The encryption key and sensitive data should be different for each environment

  ---

  Explanation/Reference:

  The MuleSoft recommended method to encrypt sensitive property data is to use the Secure Properties Tool that comes with Anypoint Studio. This tool allows encrypting properties files with a secret key and then decrypting them at runtime using the same key. The encryption key and sensitive data should be different for each environment to ensure security and avoid accidental exposure of sensitive data. https:// docs.mulesoft.com/mule-runtime.3/secure-configurationproperties

• Question 34:

  Which configurations are required for HTTP Listener to enable mTLS authentication?

  A. Set an appropriate reconnection strategy and use persistent connections for the listener
  B. Set an appropriate keystore configuration and use persistent connections for the listener
  C. Set an appropriate keystore and truststore configuration for the listener
  D. Set an appropriate truststore configuration and reconnection strategy for the listener
  C. Set an appropriate keystore and truststore configuration for the listener

  ---

  Explanation/Reference:

  To enable mTLS authentication for HTTP Listener, the developer needs to set an appropriate keystore and truststore configuration for the listener. The keystore contains the certificate and private key of the Mule application that are used to

  prove its identity to clients. The truststore contains the certificates of trusted clients that are allowed to access the Mule application.

• Question 35:

  A heathcare customer wants to use hospital system data, which includes code that was developed using legacy tools and methods. The customer has created reusable Java libraries in order to read the data from the system. What is the most effective way to develop an API retrieve the data from the hospital system?

  A. Refer to JAR files in the code
  B. Include the libraries writes deploying the code into the runtime
  C. Create the Java code in your project and invoice the data from the code
  D. Install libraries in a local repository and refer to it in the pm.xml file
  D. Install libraries in a local repository and refer to it in the pm.xml file

  ---

  Explanation/Reference:

  To develop an API that retrieves data from a hospital system using reusable Java libraries, the developer should install libraries in a local repository and refer to it in the pom.xml file. This way, the developer can use Maven to manage dependencies and invoke Java code from Mule applications using Java Module operations. https://docs.mulesoft.com/mule-runtime.3/java- module-reference#add-the-java-module-to-your-project https://docs.mulesoft.com/muleruntime/4.3/ java-module-reference#invoke-java-code

• Question 36:

  A company deploys 10 public APIs to CloudHub. Each API has its individual health endpoint defined. The platform operation team wants to configure API Functional Monitoring to monitor the health of the APIs periodically while minimizing

  operational overhead and cost.

  How should API Functional Monitoring be configured?

  A. From one public location with each API in its own schedule
  B. From one private location with all 10 APIs in a single schedule
  C. From one public location with all 10 APIs in a single schedule
  D. From 10 public locations with each API in its own schedule
  C. From one public location with all 10 APIs in a single schedule

  ---

  Explanation/Reference:

  To configure API Functional Monitoring to monitor the health of 10 public APIs periodically while minimizing operational overhead and cost, the developer should use one public location with all 10 APIs in a single schedule. A public location is a worker that runs in a CloudHub shared environment, which is cheaper and easier to maintain than a private location. A single schedule allows running all 10 APIs tests at the same time and frequency, which reduces complexity and resource consumption. https://docs.mulesoft.com/functional-monitoring/fm-create-monitor#create-a-monitor

• Question 37:

  Which plugin or dependency is required to unit test modules created with XML SDK?

  A. XMLUnit
  B. Junit
  C. MUnit Extensions Maven plugin
  D. MUnit Maven plugin
  C. MUnit Extensions Maven plugin

  ---

  Explanation/Reference:

  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.

  Reference:

  https://docs.mulesoft.com/mule-sdk.1/xml-sdk#testing

• Question 38:

  Which statement is true when using XML SDK for creating custom message processors?

  A. Properties are fields defined by an end user of the XML SDK component and serve as a global configuration for the entire Mule project in which they are used
  B. An XML SDK provides both inbound and outbound operations
  C. Operations can be reused in recursive calls
  D. All operations are public
  A. Properties are fields defined by an end user of the XML SDK component and serve as a global configuration for the entire Mule project in which they are used
  D. All operations are public

• Question 39:

  When a client and server are exchanging messages during the mTLS handshake, what is being agreed on during the cipher suite exchange?

  A. A protocol
  B. The TLS version
  C. An encryption algorithm
  D. The Public key format
  C. An encryption algorithm

  ---

  Explanation/Reference:

  A cipher suite is a set of cryptographic algorithms that are used to secure the communication between a client and a server. A cipher suite consists of four components: a key exchange algorithm, an authentication algorithm, an encryption

  algorithm, and a message authentication code (MAC) algorithm. During the cipher suite exchange, the client and the server agree on which encryption algorithm to use for encrypting and decrypting the data.

• Question 40:

  Which statement is true when working with correlation IDS?

  A. The HTTP Listener regenerates correlation IDs regardless of the HTTP request
  B. The Anypoint MQ Connector automatically propagates correlation IDS
  C. The HTTP Listener generates correlation IDS unless a correlation ID is received in the HTTP request
  D. The VM Connector does not automatically propagate correction IDs
  C. The HTTP Listener generates correlation IDS unless a correlation ID is received in the HTTP request

  ---

  Explanation/Reference:

  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. https://docs.mulesoft.com/mule-runtime.3/about-mule-message#message-attributes
