Question 1

A Mule application need to invoice an API hosted by an external system to initiate a process. The external API

takes anywhere between one minute and 24 hours to compute its process.

Which implementation should be used to get response data from the external API after it completes

processing?

Options :

A : Use an HTTP Connector to invoke the API and wait for a response

B : Use a Scheduler to check for a response every minute

C : Use an HTTP Connector inside Async scope to invoice the API and wait for a response

D : Expose an HTTP callback API in Mule and register it with the external system

Answer: D

Question 3

An API has been built to enable scheduling email provider. The front-end system does very little data entryvalidation, and problems have started to appear in the email that go to patients. A validate-customer’’ flow isadded validate the data.What is he expected behavior of the ‘validate-customer’’ flow? MCD-Level-2-page47-image13

Options :

A : If only the email address Is invalid a VALIDATION.INVALID_EMAIL error is raised

B : If the email address is invalid, processing continues to see if the appointment data and customer name are also invalid

C : If the appointment date and customer name are invalid, a SCHEDULE:INVALID_APPOINTMENT_DATE error is raised

D : If all of the values are invalid the last validation error is raised:SCHEDULE:INVALID_CUSTOMER_NAME

Answer: A

Question 4

A developer deploys an API to CloudHub and applies an OAuth policy on API Manager. During testing, theAPI response is slow, so the developer reconfigures the API so that the out-of-the-box HTTP Caching policyis applied first, and the OAuth API policy is applied second.What will happen when an HTTP request is received?

Options :

A : In case of a cache hit, both the OAuth and HTTP Caching policies are evaluated; then the cachedresponse is returned to the caller

B : In case of a cache it, only the HTTP Caching policy is evaluating; then the cached response is returnedto the caller

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

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

Answer: B

Question 5

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?

Options :

A : For nay type of queue, the message will be processed after the system comes online

B : For persistent queues, the message will be processed after the system comes online

C : For transient queues, the message will be processed after the system comes online

D : For any type of queue, the message will be lost
