SALESFORCE-MULESOFT-DEVELOPER-II Online Practice Questions and Answers

Correct Answer: B

Mutual TLS (mTLS) is an extension of TLS that requires both parties (client and server) to present their certificates to each other during the handshake process. This way, both parties can verify each other's identity and establish a secure connection. The authentication of the server happens before the authentication of the client, as the server sends its certificate first and then requests the client's certificate. https:// docs.mulesoft.com/mule-runtime.3/tls-configuration#mutualauthentication

Correct Answer: C

When the HTTP Request operation raises an HTTP CONNECTIVITY error, it triggers an on-errorcontinue handler that sets a payload with "Error in processing your request'. Since no status code is explicitly set in this handler, it defaults to 500 (INTERNAL SERVER ERROR). Therefore, the web client receives an HTTP response with status code 500 and body "Error in processing your request'. https://docs.mulesoft.com/mule- runtime.3/error-handling#on-error-continue

Correct Answer: B

In this case, the property name is tiskeystore,keyPassword, so the correct syntax is ${secure::tiskeystore,keyPassowrd}. https:// docs.mulesoft.com/mule-runtime.3/secure-configurationproperties#referencing-secure-properties

Correct Answer: D

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.

Correct Answer: D

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.

Correct Answer: A

The result of accessing route C failure is Error,errorMessage,payload.failures["2']. This is because a scatter- gather router returns an aggregated message that contains an array of results from each route and an array of failures from each

route. The failures array contains error objects with information about each failed route execution. To access route C failure, which is the third route (index 2), the developer needs to use Error.errorMessage.payload.failures["2'] expression.

Correct Answer: C

The correct sequence of activities that takes place during the Maven build and deployment is validate, initialize, compile, test package, verify, install, deploy. These are Maven lifecycle phases that define a sequence of goals to execute during

a build process. Each phase represents a stage in the build lifecycle and can have zero or more goals bound to it.

Correct Answer: D

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

Correct Answer: B

To run a test locally without the policies applied, the developer should create a properties file specifically for local development and set the API instance ID to a value that is not used in API Manager. This way, the developer can use different configuration properties for different environments and avoid triggering API autodiscovery when running tests locally. API autodiscovery is a mechanism that associates an API implementation with its corresponding API specification and policies in API Manager based on its API instance ID. By setting this ID to a value that does not exist in API Manager, the developer can prevent API autodiscovery from finding and applying any policies to the local test. https://docs.mulesoft.com/api-manager.x/api-auto-discovery-newconcept#configuring-api-autodiscovery https://docs.mulesoft.com/mule-runtime.3/configuringproperties

Correct Answer: C

To allow more than one major version of the same API to be exposed by the implementation, the developer should modify the baseUri property in the RAML file to include a variable that indicates the version number. The baseUri property defines the base URL of the API and can include variables that are replaced with actual values when mocking or deploying the API. By using a variable for the version number, the developer can expose different versions of the API using different base URLs and avoid conflicts or confusion. https:// docs.mulesoft.com/api-designer/design-modifyraml-specs#baseuri https://docs.mulesoft.com/api-manager.x/api-versioning
