Question #2

A Mule application includes a subflow containing a Scatter-Gather scope. Within each leg of the Scatter- Gather, an HTTP connector calls a PUT endpoint to modify records in different upstream systems. The subflow is called from inside an Until Successful scope to retry if a transient exception is raised.
A technical spike is being performed to increase reliability of the Mule application.
Which steps should be performed within the Mule flow above to ensure idempotent behavior?

  • A. Ensure an error-handling flow performs corrective actions to roll back all changes if any leg of the Scatter-Gather fails
  • B. Change the PUT requests inside the Scatter-Gather to POST requests
  • C. Remove the PUT requests from the Scatter-Gather and perform them sequentially
  • D. None; the flow already exhibits idempotent behavior

Question #3

A System API that communicates to an underlying MySQL database is deployed to CloudHub. The DevOps team requires a readiness endpoint to monitor all system APIs.
Which strategy should be used to implement this endpoint?

  • A. Create a dedicated endpoint that responds with the API status only
  • B. Use an existing resource endpoint of the API
  • C. Create a dedicated endpoint that responds with the API status and health of the server
  • D. Create a dedicated endpoint that responds with the API status and reachability of the underlying systems

Question #4

A Mule implementation uses an HTTP Request within an Until Successful scope to connect to an API.
How should a permanent error response like HTTP:UNAUTHORIZED be handled inside Until Successful to reduce latency?

  • A. In Until Successful configuration, set the retry count to 1 for error type HTTP:UNAUTHORIZED.
  • B. Put the HTTP Request inside a try scope in Until Successful. In the error handler, use On Error Propagate to catch permanent errors like HTTP:UNAUTHORIZED.
  • C. Put the HTTP Request inside a try scope in Until Successful. In the error handler, use On Error Continue to catch permanent errors like HTTP:UNAUTHORIZED.
  • D. Continue retrying until a MULE:RETRY_EXHAUSTED error is raised or the API responds back with a successful response.

  • C. Store the contents of the file on separate storage, and store the key and location of the file using Object Store v2
