NEW QUESTION # 16
When implementing a synchronous API where the event source is an HTTP Listener, a developer needs to return the same correlation ID back to the caller in the HTTP response header.
How can this be achieved?
- A. NO action is needed as the correlation ID is returned to the caller in the response header by default
- B. Enable the CorrelationID checkbox in the HTTP Listener configuration
- C. Enable the auto-generate CorrelationID option when scaffolding the flow
- D. Configure a custom correlation policy
Answer: A
Explanation:
Explanation
When implementing a synchronous API where the event source is an HTTP Listener, Mule automatically propagates some message attributes between flows via outbound and inbound properties. One of these attributes is correlation ID, which is returned to the caller in the response header by default as MULE_CORRELATION_ID. References:

NEW QUESTION # 25
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 each client subscribe directly to the exchange.
Have each client subscribe directly to the queue. - B. 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 - C. 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. - D. Publish the gate change notification to an Anypoint MC queue
Have each client subscribe directly to the queue
Answer: C
Explanation:
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. References:

NEW QUESTION # 26
A Mule implementation uses a HTTP Request within an Unit Successful scope to connect to an API.
How should a permanent error response like HTTP:UNAUTHORIZED be handle inside Until Successful to reduce latency?
- A. Put the HTTP Request inside a try scope in Unit Successful.
In the error handler, use On Error Propagate to catch permanent errors like HTTP UNAUTHORIZED. - B. Put the HTTP Request inside a try scope in Unit Successful.
In the error handler, use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED. - C. Configure retrying until a MULERETRY_EXHAUSTED error is raised or the API responds back with a successful response.
- D. In Until Successful configuration, set the retry count to 1 for error type HTTP: UNAUTHORIZED.
Answer: B
Explanation:
Explanation
To handle a permanent error response like HTTP:UNAUTHORIZED inside Until Successful, the developer should put the HTTP Request inside a try scope in Unit Successful, and use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED in the error handler. This way, the developer can avoid retrying requests that will always fail due to a permanent error, and reduce latency. On Error Continue allows the flow to continue processing after handling the error. References:

- A. Use ''Before Test Case'' To collect data from Flow-1 test cases before running Flow-2 test cases
- B. Chain together the test suites and test cases for Flow-1 and Flow-2
- C. Use 'After Test Case' to produce the data needed from Flow-1 test cases to pass to Flow-2 test cases
- D. Use ''Set Event to pass the input that is needed, and keep the test cases for Flow-1 and Flow-2 independent
Answer: D
Explanation:
Explanation
To ensure the test suites and test cases written for Flow-1 and Flow-2 will execute successfully, the developer should use a Set Event processor to pass the input that is needed by Flow-2, and keep the test cases for Flow-1 and Flow-2 independent. This way, the developer can isolate the testing of each flow and avoid coupling them together. References: https://docs.mulesoft.com/munit/2.3/munit-test-flow
NEW QUESTION # 29
A developer is working on a project that requires encrypting all data before sending it to a backend application. To accomplish this, the developer will use PGP encryption in the Mule 4 Cryptography module.
What is required to encrypt the data before sending it to the backend application?
- A. The application needs the public key from the backend service to encrypt the data
- B. The application needs to configure HTTPS TLS context information to encrypt the data
- C. The application needs to both the private and public keys to encrypt the data
- D. The application needs the private key from the backend service to encrypt the data
Answer: A
Explanation:
Explanation
To encrypt the data before sending it to the backend application using PGP encryption, the application needs the public key from the backend service. PGP encryption uses a public-key cryptography system, which means that each party has a pair of keys: a public key and a private key. The public key is used to encrypt data, and the private key is used to decrypt data. Therefore, to encrypt data for a specific recipient (the backend service), the application needs to use the recipient's public key. The recipient can then use its own private key to decrypt the data.

NEW QUESTION # 30
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. Object Store Connector
- B. CloudHub REST API
- C. Object Store v2 REST API
- D. CloudHub Connector
Answer: C
Explanation:
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.
References: https://docs.mulesoft.com/object-store/osv2-apis
NEW QUESTION # 31
Two APIs are deployed to a two-node on-prem cluster. Due to a requirements change, the two APIs must communicate to exchange data asynchronously.
- A. The VM Connector is used to inter-application communication, so it is not possible to use the VM Connector
- B. Instead of using the VM Connector use <flow-ref>directly
- C. It is not possible to use the VM Connector since the APIs are running in a cluster mode and each mode has it own set of VM Queues
- D. If the two APIs use the same domain, the VM Connector can be leveraged
Answer: D
Explanation:
Explanation
To communicate asynchronously between two APIs deployed to a two-node on-prem cluster, the developer can use the VM Connector if the two APIs use the same domain. The VM Connector allows passing messages between different Mule applications within a single Mule runtime instance or across different instances using shared memory or persistent storage. If two APIs are deployed under the same domain, they can share resources such as VM queues and communicate asynchronously using VM Connector operations. References:

NEW QUESTION # 32
A healthcare portal needs to validate the token that it sends to a Mule API. The developer plans to implement a custom policy using the HTTP Policy Transform Extension to match the token received in the header from the heathcare portal.
Which files does the developer need to create in order to package the custom policy?
- A. XML template file, YAML configuration file
- B. JSON properties file, YAML configuration file
- C. JSON properties file, XML template file
- D. Deployable ZIP file, YAML configuration file
Answer: A
Explanation:
Explanation
To package a custom policy using the HTTP Policy Transform Extension, the developer needs to create an XML template file and a YAML configuration file. The XML template file defines the policy logic using Mule components and placeholders for user-defined properties. The YAML configuration file defines the metadata of the policy, such as its name, description, category, parameters, and dependencies. References:
https://docs.mulesoft.com/api-manager/2.x/http-policy-transform#packaging-the-policy
NEW QUESTION # 33
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. Apply the JSON Schema policy in API Manager and reference the correct schema in the policy configuration
- B. Add the JSON module dependency and add the validate-schema operation in the flow, configured to reference the schema
- C. Using the DataWeave if Else condition test the values of the payload against the examples included in the schema
- D. Use a DataWeave 2.09 transform operation, and at the log of the DataWeave script, add:
%dw 2.0
Import.json-moduls
Answer: B
Explanation:
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. References:
https://docs.mulesoft.com/json-module/1.1/json-validate-schema
NEW QUESTION # 34
Refer to the exhibit.
A developer generates the base scaffolding for an API in Anypoint Studio.
Which HTTP status code is returned while testing using the API Kit console if no values are entered in client-secret?
- A. HTTP status code:500
- B. HTTP status code:400
- C. HTTP status code:200
- D. HTTP status code:403
Answer: D
Explanation:
Explanation
Based on the code snippet and schema.json file below, when testing using the API Kit console if no values are entered in client-secret, HTTP status code 403 (FORBIDDEN) is returned. This is because client-secret is defined as a required header parameter in schema.json file, which means that it must be present in every request. If no values are entered in client-secret, then it is equivalent to omitting this header parameter, which violates the schema and causes APIKit Router to return HTTP status code 403. References:
https://docs.mulesoft.com/apikit/4.x/apikit-4-headers
NEW QUESTION # 35
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. Anypoint Studio secures the value
- C. Runtime Manager masks the value
- D. The Mule server encrypts the value
Answer: C
Explanation:
Explanation
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. References:
https://docs.mulesoft.com/runtime-manager/runtime-manager-agent-for-mule4#properties-tab
NEW QUESTION # 36
Which pattern should be used to invoke multiple HTTP APIs in parallel and roll back failed requests in sequence?
- A. A Parallel for Each scope with each HTTP request wrapped in a Try scope
- B. VM queues as a reliability pattern with error handlers to roll back any requests
- C. A database as a transactional outbox and an Until Successful router to retry any requests
- D. Scatter-Gather as central Saga orchestrator for all API request with compensating actions for failing routes
Answer: D
Explanation:
Explanation
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. References:
