NEW QUESTION # 30
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. VM queues as a reliability pattern with error handlers to roll back any requests
- C. A Parallel for Each scope with each HTTP request wrapped in a Try scope
- 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:

NEW QUESTION # 32
A mule application exposes and API for creating payments. An Operations team wants to ensure that the Payment API is up and running at all times in production.
Which approach should be used to test that the payment API is working in production?
- A. Create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API
- B. Create a health check endpoint that reuses the same port number and HTTP Listener configuration as the API itself
- C. Monitor the Payment API directly sending real customer payment data
- D. Configure the application to send health data to an external system
Answer: A
Explanation:
Explanation
To test that the payment API is working in production, the developer should create a health check endpoint that listens on a separate port and uses a separate HTTP Listener configuration from the API. This way, the developer can isolate the health check endpoint from the API traffic and avoid affecting the performance or availability of the API. The health check endpoint should return a simple response that indicates the status of the API, such as OK or ERROR. References:
https://docs.mulesoft.com/api-functional-monitoring/afm-create-monitor#create-a-monitor
NEW QUESTION # 33
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. Any of the APIkit generate implement flows
- C. Northing because flowRef is an optional attribute which can be passed runtime
- D. The name of the flow that has HTTP listener to receive all incoming RESTful operation requests
Answer: D
Explanation:
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. References:
https://docs.mulesoft.com/api-manager/2.x/api-auto-discovery-new-concept#flowref

What required changes can be made to give a partial successful response in case the United Airlines API returns with a timeout?
- A. 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 - B. 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 - C. 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. - 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 Propagate scope.
Answer: C
Explanation:
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.

NEW QUESTION # 38
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. Use a DataWeave 2.09 transform operation, and at the log of the DataWeave script, add:
%dw 2.0
Import.json-moduls - D. Using the DataWeave if Else condition test the values of the payload against the examples included in the schema
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 # 39
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. A1, B1, F1, B2, A2
- B. F1, A1, B1, B2, A2
- C. B1, A1, F1, A2, B2
- D. F1, B1, A1, A2, B2
Answer: A
Explanation:
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. References:
https://docs.mulesoft.com/api-manager/2.x/policies-policy-order

- A. The HTTP listener will only accept HTTP requests
- B. Mutual TLS authentication will be enabled between this HTTP Listener and an HTTP client
- C. The HTTP Listener will trust any certificate presented by the HTTP client
- D. The HTTP Lister will accept any unauthenticated request
Answer: A
Explanation:
Explanation
Based on the exhibit below, if 'Insecure' is selected as part of the HTTP Listener configuration, the HTTP listener will only accept HTTP requests. This means that no TLS context will be configured for this listener and no encryption or authentication will be applied to incoming requests. The protocol attribute of this listener will be set to HTTP instead of HTTPS. References:
https://docs.mulesoft.com/http-connector/1.6/http-listener-ref#insecure
NEW QUESTION # 46
Which statement is true when working with correlation IDS?
- A. The VM Connector does not automatically propagate correction IDs
- B. The HTTP Listener generates correlation IDS unless a correlation ID is received in the HTTP request
- C. The HTTP Listener regenerates correlation IDs regardless of the HTTP request
- D. The Anypoint MQ Connector automatically propagates correlation IDS
Answer: B
Explanation:
Explanation
When working with correlation IDs, the HTTP Listener generates correlation IDs unless a correlation ID is received in the HTTP request. In that case, it propagates the received correlation ID throughout the flow execution. Correlation IDs are used to track events across different flows or applications. References:
https://docs.mulesoft.com/mule-runtime/4.3/about-mule-message#message-attributes
NEW QUESTION # 47
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.
