Question 2

A company is planning to extend its Mule APIs to the Europe region. Currently all new applications are deployed to Cloudhub in the US region following this naming convention
{API name}-{environment}. for example, Orders-SAPI-dev, Orders-SAPI-prod etc.
Considering there is no network restriction to block communications between API's, what strategy should be implemented in order to apply the same new API's running in the EU region of CloudHub as well to minimize latency between API's and target users and systems in Europe?

A. Set region property to Europe (eu-de) in API manager for all the mule application No need to change the naming convention B. Set region property to Europe (eu-de) in runtime manager for all the mule application Change the naming convention to {API name}-{environment}-{region} and communicate this change to the consuming applications and users C. Set region property to Europe (eu-de) in API manager for all the mule application Change the naming convention to {API name}-{environment}-{region} and communicate this change to the consuming applications and users D. Set region property to Europe (eu-de) in runtime manager for all the mule application No need to change the naming convention

Question 5

A Mule application is running on a customer-hosted Mule runtime in an organization's network. The Mule application acts as a producer of asynchronous Mule events. Each Mule event must be broadcast to all interested external consumers outside the Mule application. The Mule events should be published in a way that is guaranteed in normal situations and also minimizes duplicate delivery in less frequent failure scenarios.
The organizational firewall is configured to only allow outbound traffic on ports 80 and 443. Some external event consumers are within the organizational network, while others are located outside the firewall.
What Anypoint Platform service is most idiomatic (used for its intended purpose) for publishing these Mule events to all external consumers while addressing the desired reliability goals?

A. Anypoint Exchange B. CloudHub VM queues C. Anypoint MQ D. CloudHub Shared Load Balancer

Question 6

An XA transaction Is being configured that involves a JMS connector listening for Incoming JMS messages.
What is the meaning of the timeout attribute of the XA transaction, and what happens after the timeout expires?

A. The time that is allowed to pass between committing the transaction and the completion of the Mule flow After the timeout, flow processing triggers an error B. The time that Is allowed to pass without the transaction being ended explicitly After the timeout, the transaction Is forcefully rolled-back C. The time that Is allowed to pass for state JMS consumer threads to be destroyed After the timeout, a new JMS consumer thread is created D. The time that Is allowed to pass between receiving JMS messages on the same JMS connection After the timeout, a new JMS connection Is established

Question 7

An organization has strict unit test requirement that mandate every mule application must have an MUnit test suit with a test case defined for each flow and a minimum test coverage of 80%.
A developer is building Munit test suit for a newly developed mule application that sends API request to an external rest API.
What is the effective approach for successfully executing the Munit tests of this new application while still achieving the required test coverage for the Munit tests?

A. Mark the rest API invocations in the Munits and then call the mocking service flow that simulates standard responses from the REST API B. Invoke the external endpoint of the rest API from the mule floors C. Mock the rest API invocation in the Munits and return a mock response for those invocations D. Create a mocking service flow to simulate standard responses from the rest API and then configure the mule flows to call the marking service flow

Question 10

A retail company is implementing a MuleSoft API to get inventory details from two vendors by Invoking each vendor's online applications. Due to network issues, the invocations to the vendor applications are timing out intermittently, but the requests are successful after re-invoking each vendor application.
What is the most performant way of implementing the API to invoke each vendor application and to retry invocations that generate timeout errors?

A. Use a Choice scope to Invoke each vendor application on a separate route.
Place the Choice scope inside an Until-Successful scope to retry requests that raise timeout errors. B. Use a Round-Robin scope to invoke each vendor application on a separate route.
Use a Try-Catch scope in each route to retry requests that raise timeout errors. C. Use a For-Each scope to invoke the two vendor applications in series, one after the other.
Place the For-Each scope inside an Until-Successful scope to retry requests that raise timeout errors. D. Use a Scatter-Gather scope to invoke each vendor application on a separate route.
Use an Until-Successful scope in each route to retry requests that raise timeout errors.

Question 11

Mule application A receives a request Anypoint MQ message REQU with a payload containing a variable-length list of request objects. Application A uses the For Each scope to split the list into individual objects and sends each object as a message to an Anypoint MQ queue.
Service S listens on that queue, processes each message independently of all other messages, and sends a response message to a response queue.
Application A listens on that response queue and must in turn create and publish a response Anypoint MQ message RESP with a payload containing the list of responses sent by service S in the same order as the request objects originally sent in REQU.
Assume successful response messages are returned by service S for all request messages.
What is required so that application A can ensure that the length and order of the list of objects in RESP and REQU match, while at the same time maximizing message throughput?

A. Keep track of the list length and all object indices in REQU, both in the For Each scope and in all communication involving service Use persistent storage when creating RESP B. Perform all communication involving service S synchronously from within the For Each scope, so objects in RESP are in the exact same order as request objects in REQU C. Use a Scatter-Gather within the For Each scope to ensure response message order Configure the Scatter-Gather with a persistent object store D. Use an Async scope within the For Each scope and collect response messages in a second For Each scope in the order In which they arrive, then send RESP using this list of responses
