NEW QUESTION # 11
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?
- A. In 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
- B. In case of a cache it, only the HTTP Caching policy is evaluating; then the cached response is returned to the caller
- C. In case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cached response is returned to the caller
- D. In 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
Explanation:
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.

NEW QUESTION # 12
A scatter-gather router is configured with four routes:Route A, B, C and D.
Route C false.
- A. Payload ['2']
- B. Payload failures['2']
- C. Error,errorMesage.payload.results ['2']
- D. Error,errorMessage,payload.failures['2']
Answer: C
Explanation:
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
NEW QUESTION # 13
Which configurations are required for HTTP Listener to enable mTLS authentication?
- A. Set an appropriate keystore configuration and use persistent connections for the listener
- B. Set an appropriate keystore and truststore configuration for the listener
- C. Set an appropriate truststore configuration and reconnection strategy for the listener
- D. Set an appropriate reconnection strategy and use persistent connections for the listener
Answer: B
Explanation:
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
NEW QUESTION # 14
Mule application A is deployed to CloudHub and is using Object Store v2. Mute application B is also deployed to CloudHub.
Which approach can Mule application B use to remove values from Mule application A'S Object Store?
- A. CloudHub REST API
- B. Object Store v2 REST API
- C. CloudHub Connector
- D. Object Store Connector
Answer: B
Explanation:
To remove values from Mule application A's Object Store v2, Mule application B can use Object Store v2 REST API. This API allows performing operations on Object Store v2 resources using HTTP methods, such as GET, POST, PUT, and DELETE. Mule application B can use the DELETE method to remove values from Mule application A's Object Store v2 by specifying the object store ID and the key of the value to delete. Reference: https://docs.mulesoft.com/object-store/osv2-apis
NEW QUESTION # 15
A Flight Management System publishes gate change notification events whenever a flight's arrival gate changes. Other systems, including Baggage Handler System. Inflight Catering System and Passenger Notifications System, must each asynchronously receive the same gate change notification to process the event according.
Which configuration is required in Anypoint MQ to achieve this publish/subscribe model?
- A. Publish the gate change notification to an Anypoint MQ exchanhe.
Create different Anypoint MQ queues meant for each of the other subscribing systems.Bind the exchange with each of the queues. - B. Publish each client subscribe directly to the exchange.
Have each client subscribe directly to the queue. - C. Publish the gate change notification to an Anypoint MC queue
Have each client subscribe directly to the queue - D. Publish the gate change notification to an Anypoint MQ queue.
Create different anypoint MQ exchange meant for each of the other subscribing systems Bind the queue with each of the exchanges
Answer: A
Explanation:
To achieve a publish/subscribe model using Anypoint MQ, where each system receives the same gate change notification event, the developer should publish the gate change notification to an Anypoint MQ exchange, create different Anypoint MQ queues meant for each of the other subscribing systems, and bind the exchange with each of the queues. An exchange is a message routing agent that can send messages to different queues based on predefined criteria. By binding an exchange with multiple queues, each queue receives a copy of every message sent to that exchange. Therefore, each system can subscribe to its own queue and receive every gate change notification event. Reference: https://docs.mulesoft.com/anypoint-mq/3.x/anypoint-mq-exchanges
NEW QUESTION # 16
A Mule application contain two policies Policy A and Policy A has order1, and Policy B has order 2. Policy A Policy B, and a flow are defined by he configuration below.
When a HTTP request arrives at the Mule application's endpoint, what will be the execution order?
- A. F1, A1, B1, B2, A2
- B. F1, B1, A1, A2, B2
- C. B1, A1, F1, A2, B2
- D. A1, B1, F1, B2, A2
Answer: D
Explanation:
Based on the configuration below, when a HTTP request arrives at the Mule application's endpoint, the execution order will be A1, B1, F1, B2, A2. This is because policies are executed before and after the API implementation flow according to their order attribute. Policy A has order 1, which means it is executed first before Policy B, which has order 2. The flow is executed after both policies are executed before the flow. Then, Policy B is executed after the flow before Policy A is executed after the flow. Reference: https://docs.mulesoft.com/api-manager/2.x/policies-policy-order
NEW QUESTION # 17
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 PKCS12 -destkeystore keystore.p12 -deststoretype JKS
- D. Keytool-importkeystore -srckeystore keystore jks-srcstoretype JKS -destkeystore keystore.p13 -deststoretype PKCS12
Answer: B
Explanation:
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). Reference: https://docs.oracle.com/en/java/javase/11/tools/keytool.html#GUID-5990A2E4-78E3-47B7-AE75-6D1826259549
NEW QUESTION # 18
A Mule application uses API autodiscovery to access and enforce policies for a RESTful implementation.
- A. The name of the flow that has APlkit Console to receive all incoming RESTful operation requests.
- B. Northing because flowRef is an optional attribute which can be passed runtime
- C. The name of the flow that has HTTP listener to receive all incoming RESTful operation requests
- D. Any of the APIkit generate implement flows
Answer: C
Explanation:
To use API autodiscovery to access and enforce policies for a RESTful implementation, flowRef must be set to the name of the flow that has HTTP listener to receive all incoming RESTful operation requests. This way, API autodiscovery can identify the API implementation and associate it with the corresponding API specification and policies in API Manager. The flow that has HTTP listener is usually the main flow that contains the APIKit Router. Reference: https://docs.mulesoft.com/api-manager/2.x/api-auto-discovery-new-concept#flowref
NEW QUESTION # 19
Refer to the exhibits.
Bioinfo System API is implemented and published to Anypoint Exchange. A developer wants to invoke this API using its REST Connector.
What should be added to the POM?
- A.
- B.
- C.
- D.
- E.
Answer: A
Explanation:
To invoke Bioinfo System API using its REST Connector, option E should be added to the pom.xml file. This option adds a dependency for Bioinfo System API REST Connector with its group ID, artifact ID, version, classifier, and type. The classifier specifies that it is a REST Connector (raml-client), and the type specifies that it is a Mule plugin (mule-plugin). Reference: https://docs.mulesoft.com/apikit/4.x/apikit-4-generate-from-rest-api-task#add-the-api-dependency-to-the-pom-file
NEW QUESTION # 20
A Mule application deployed to a standardalone Mule runtime uses VM queues to publish messages to be consumed asynchronously by another flow.
In the case of a system failure, what will happen to in-flight messages in the VM queues that have been consumed?
- A. For nay type of queue, the message will be processed after the system comes online
- B. For any type of queue, the message will be lost
- C. For persistent queues, the message will be processed after the system comes online
- D. For transient queues, the message will be processed after the system comes online
Answer: C
Explanation:
In case of a system failure, in-flight messages in persistent VM queues that have been consumed will be processed after the system comes online. This is because persistent VM queues store messages on disk and guarantee delivery even if there is a system crash or restart. Therefore, any in-flight messages that have been consumed but not processed will be recovered from disk and processed when the system is back online. Reference: https://docs.mulesoft.com/mule-runtime/4.3/vm-connector#persistent-queues
NEW QUESTION # 21
The flow is invoicing a target API. The API's protocol is HTTPS. The TLS configuration in the HTTP Request Configuration global element is set to None. A web client submits a request to http:localhost:8081/vehicles.
If the certificate of the target API is signed by a certificate authority (CA), what is true about the HTTP Request operation when the flow executes?
- A. The HTTP Request operation will succeed if the CA'S certificate is present in the JRE's default keystore
- B. The HTTP Request operation will succeed if the CA's certificate is present in the JRE's default truststore.
- C. The HTTP Request operation will always fail regardless of the CA
- D. The HTTP Request operation will always succeed regardless of the CA
Answer: B
Explanation:
The HTTP Request operation will use the default truststore of the JRE to validate the certificate of the target API. If the CA's certificate is present in the truststore, the operation will succeed. Otherwise, it will fail with a handshake exception. Reference: https://docs.mulesoft.com/mule-runtime/4.3/tls-configuration#tls-default
NEW QUESTION # 22
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. Add the JSON module dependency and add the validate-schema operation in the flow, configured to reference the schema
- B. Use a DataWeave 2.09 transform operation, and at the log of the DataWeave script, add:
%dw 2.0
Import.json-moduls - C. Using the DataWeave if Else condition test the values of the payload against the examples included in the schema
- D. Apply the JSON Schema policy in API Manager and reference the correct schema in the policy configuration
Answer: A
Explanation:
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. Reference: https://docs.mulesoft.com/json-module/1.1/json-validate-schema
NEW QUESTION # 23
Refer to the exhibit.
A Mule application pom.xml configures the Maven Resources plugin to exclude parsing binary files in the project's src/main/resources/certs directory.
Which configuration of this plugin achieves a successful build?
- A.
- B.
- C.
- D.
Answer: C
Explanation:
To configure the Maven Resources plugin to exclude parsing binary files in the project's src/main/resources/certs directory, option C should be used. This option specifies that any files with .cer or .jks extensions under the certs directory should be excluded from filtering. Filtering is a process of replacing placeholders with actual values in resource files during the build process. Binary files should not be filtered because they may become corrupted or unusable. Reference: https://maven.apache.org/plugins/maven-resources-plugin/examples/filter.html https://maven.apache.org/plugins/maven-resources-plugin/examples/include-exclude.html
NEW QUESTION # 24
An API has been developed and deployed to CloudHub Among the policies applied to this API is an allowlist of IP addresses. A developer wants to run a test in Anypoint Studio and does not want any policies applied because their workstation is not included in the allowlist.
What must the developer do in order to run this test locally without the policies applied?
- A. Deactivate the API in API Manager so the Autodiscovery element will not find the application when it runs in Studio
- B. Create a properties file specifically for local development and set the API instance ID to a value that is not used in API Manager
- C. Run the test as-s, with no changes because the Studio runtime will not attempt to connect to API Manager
- D. Pass in the runtime parameter ''-Danpow.platform.gatekeeper=disabled''
Answer: D
Explanation:
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. Reference: https://docs.mulesoft.com/api-manager/2.x/api-auto-discovery-new-concept#configuring-api-autodiscovery https://docs.mulesoft.com/mule-runtime/4.3/configuring-properties
NEW QUESTION # 25
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?
- A. Add 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. - B. Add Flow Reference components inside a Try scope.
Set the payload to a default value'' insider the error handler using the ON Error Continue scope - C. Add Flow Reference components inside a Try scope
Set the payload to a default value '' inside the error handler using the On Error Propagate scope - D. Add 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
Explanation:
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. Reference: https://docs.mulesoft.com/mule-runtime/4.3/scatter-gather-concept https://docs.mulesoft.com/mule-runtime/4.3/try-scope-concept https://docs.mulesoft.com/mule-runtime/4.3/on-error-continue-concept
