• Question 31:

  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. Access Anypoint Monitoring's built-in dashboard Seclect a resource. Create a custom dashboard to retrieve the information.

  C. Access Anypoint Monitoring built-in dashboard. Select a resource. Locate the information under Log Manager < Raw Data.

  D. Change the API Implementation to capture the information in the log. Retrieve the information from the log file.

  Correct Answer: A

  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. https:// docs.mulesoft.com/monitoring/built-indashboard-reference

• Question 32:

  A new Mule project has been created in Anypoint Studio with the default settings. Which file inside the Mule project must be modified before using Maven to successfully deploy the application?

  A. Settings.xml

  B. Config.yaml

  C. Pom.xml

  D. Mule.artificact.json

  Correct Answer: C

  To use Maven to successfully deploy the application, the developer needs to modify the pom.xml file inside the Mule project. The pom.xml file contains the configuration and dependencies of the Mule application, as well as the deployment information such as the CloudHub region, environment, and worker size. The developer needs to specify these properties in the pom.xml file before using Maven to deploy the application. https:// docs.mulesoft.com/mule-runtime.3/mmpconcept# application-deployment-descriptor

• Question 33:

  Which command is used to convert a JKS keystore to PKCS12?

  A. Keytool-importkeystore "srckeystore keystore p12-srcstoretype PKCS12 "destkeystore keystore.jks "deststoretype JKS

  B. Keytool-importkeystore "srckeystore keystore p12-srcstoretype JKS "destkeystore keystore.p12 " deststoretype PKCS12

  C. Keytool-importkeystore "srckeystore keystore jks-srcstoretype JKS "destkeystore keystore.p13 " deststoretype PKCS12

  D. Keytool-importkeystore "srckeystore keystore jks-srcstoretype PKCS12 "destkeystore keystore.p12 "deststoretype JKS

  Correct Answer: B

  To convert a JKS keystore to PKCS12, the developer needs to use the keytool-importkeystore command with the following options: -srckeystore keystore.jks -srcstoretype JKS -destkeystore keystore.p12 -deststoretype PKCS12. This

  command imports all entries from a source JKS keystore (keystore.jks) into a destination PKCS12 keystore (keystore.p12).

• 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

  Correct Answer: C

  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 scatter-gather router is configured with four routes:Route A, B, C and D. Route C false.

  A. Error,errorMesage.payload.results ["2']

  B. Payload failures["2']

  C. Error,errorMessage,payload.failures["2']

  D. Payload ["2']

  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.

• Question 36:

  Which properties are mandatory on the HTTP Connector configuration in order to use the OAuth 2.0 Authorization Code grant type for authentication?

  A. External callback URL, access token URL, client ID response access token

  B. Token URL, authorization URL, client ID, client secret local callback URL

  C. External callback URL, access token URL, client ID, response refresh token

  D. External callback URL, access token URL, local authorization URL, authorization URL, client ID, client secret

  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.

• Question 37:

  Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?

  A. A database as a transactional outbox and an Until Successful router to retry any requests

  B. A Parallel for Each scope with each HTTP request wrapped in a Try scope

  C. Scatter-Gather as central Saga orchestrator for all API request with compensating actions for failing routes

  D. VM queues as a reliability pattern with error handlers to roll back any requests

  Correct Answer: C

  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. https://docs.mulesoft.com/ mule-runtime.3/scattergather-concept https://docs.mulesoft.com/mule-runtime.3/saga

• Question 38:

  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?

  A. Create a Mule plugin project Create a common-global-error-handler flow inside the plugin project. Use this plugin as a dependency in all Mute applications. Import that configuration file in Mute applications.

  B. Create a common-global-error-handler flow in all Mule Applications Refer to it flow-ref wherever needed.

  C. Create a Mule Plugin project Create a common-global-error-handler flow inside the plugin project. Use this plugin as a dependency in all Mule applications

  D. Create a Mule daman project. Create a common-global-error-handler flow inside the domain project. Use this domain project as a dependency.

  Correct Answer: C

  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-globalerror- 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.

• Question 39:

  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?

  A. Use a DataWeave 2.09 transform operation, and at the log of the DataWeave script, add: %dw 2.0 Import.json-moduls

  B. Using the DataWeave if Else condition test the values of the payload against the examples included in the schema

  C. Apply the JSON Schema policy in API Manager and reference the correct schema in the policy configuration

  D. Add the JSON module dependency and add the validate-schema operation in the flow, configured to reference the schema

  Correct Answer: D

  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. https://docs.mulesoft.com/jsonmodule/1.1/json-validate-schema

• Question 40:

  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?

  A. CloudHub encrypts the value

  B. The Mule server encrypts the value

  C. Anypoint Studio secures the value

  D. Runtime Manager masks the value

  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.
