Question 1

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?

AAdd 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.

BAdd Flow Reference components inside a Try scope.
Set the payload to a default value'' insider the error handler using the ON Error Continue scope

CAdd Flow Reference components inside a Try scope
Set the payload to a default value '' inside the error handler using the On Error Propagate scope

DAdd 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.

Answer : D

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.

Question 2

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?

ASettings.xml

BConfig.yaml

CPom.xml

DMule.artificact.json

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.

Question 3

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

AKeytool-importkeystore --srckeystore keystore p12-srcstoretype PKCS12 --destkeystore keystore.jks --deststoretype JKS

BKeytool-importkeystore --srckeystore keystore p12-srcstoretype JKS --destkeystore keystore.p12 --deststoretype PKCS12

CKeytool-importkeystore --srckeystore keystore jks-srcstoretype JKS --destkeystore keystore.p13 --deststoretype PKCS12

DKeytool-importkeystore --srckeystore keystore jks-srcstoretype PKCS12 --destkeystore keystore.p12 --deststoretype JKS

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 4

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

ASet an appropriate reconnection strategy and use persistent connections for the listener

BSet an appropriate keystore configuration and use persistent connections for the listener

CSet an appropriate keystore and truststore configuration for the listener

DSet an appropriate truststore configuration and reconnection strategy for the listener

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. Reference: https://docs.mulesoft.com/mule-runtime/4.3/tls-configuration#mutual-authentication

Question 5

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

Route C false.

AError,errorMesage.payload.results ['2']

BPayload failures['2']

CError,errorMessage,payload.failures['2']

DPayload ['2']

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 6

The HTTP Request operation raises an HTTP CONNECTIVITY error.

Which HTTP status code and body are returned to the web client?

AHTTP Status Code:200.
Body 'Error in processing your request

BHTTP Status Code:500.
Body 'The HTTP CONNECTIVITY Error description

CHTTP Status Code:500.
Body 'Error in processing your request

DHTTP Status Code:500.
Body 'Error in processing your request

Answer : C

When the HTTP Request operation raises an HTTP CONNECTIVITY error, it triggers an on-error-continue 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'.

Question 7

A system API that communicates to an underlying MySQL database is deploying to CloudHub. The DevOps team requires a readiness endpoint to monitor all system APIs.

Which strategy should be used to implement this endpoint?

ACreate a dedicated endpoint that responds with the API status and reachability of the underlying systems

BCreate a dedicated endpoint that responds with the API status and health of the server

CUse an existing resource endpoint of the API

DCreate a dedicated endpoint that responds with the API status only

Answer : A

To implement a readiness endpoint to monitor all system APIs, the developer should create a dedicated endpoint that responds with the API status and reachability of the underlying systems. This way, the DevOps team can check if the system API is ready to receive requests and if it can communicate with its backend systems without errors.
