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. Reference: https://docs.mulesoft.com/mule-runtime/4.3/scatter-gather-reference#scatter-gather-output

Question 6

A developer deploys an API to CloudHub and applies an OAuth policy on API Manager. During testing, the API response is slow, so the developer reconfigures the API so that the out-of-the-box HTTP Caching policy is applied first, and the OAuth API policy is applied second.

What will happen when an HTTP request is received?

AIn case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cached response is returned to the caller

BIn case of a cache it, only the HTTP Caching policy is evaluating; then the cached response is returned to the caller

CIn case of a cache miss, only the HTTP Caching policy is evaluated; then the API retrieves the data from the API implementation, and the policy stores the data to be cached in Object Store

DIn case of a cache miss, both the OAuth and HTTP Caching policies are evaluated; then the API retrieves the data from the API implementation, and the policy does not store the data in Object Store

Answer : B

When an HTTP request is received and the HTTP Caching policy is applied first, it checks if there is a cached response for that request in Object Store. If there is a cache hit, meaning that a valid cached response exists, then only the HTTP Caching policy is evaluated and the cached response is returned to the caller without invoking the OAuth policy or the API implementation. If there is a cache miss, meaning that no valid cached response exists, then both the HTTP Caching policy and the OAuth policy are evaluated before invoking the API implementation. Reference: https://docs.mulesoft.com/api-manager/2.x/http-caching-policy#policy-ordering

Question 7

Refer to the exhibit.

What action must be performed to log all the errors raised by the VM Connector?

AAdd <AsyncLOgger name='orgroute.extensions vm' level=ERROR'I> inside the Logger tag

BAdd <AsyncLOgger name='orgroute.extensions vm' level=ERROR'/> inside the Appenders tag

CConfigure <Logger level-'ERROR'/> inside the VM Connector configuration

DNothing, as error-level events are automatically logged

Answer : B

To log all the errors raised by the VM Connector, the developer needs to add an async logger with the name 'org.mule.extension.vm' and the level 'ERROR' inside the appenders tag of the log4j2.xml file. This will enable logging all error-level events generated by the VM Connector to the console appender.
