Salesforce Exam Salesforce MuleSoft Developer II Topic 4 Question 21 Discussion

Actual exam question for Salesforce's Salesforce MuleSoft Developer II exam
Question #: 21
Topic #: 4
[All Salesforce MuleSoft Developer II Questions]

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?

Show Suggested Answer Hide Answer
Suggested Answer: D

To get response data from the external API after it completes processing, the developer should expose an HTTP callback API in Mule and register it with the external system. This way, the external API can invoke the callback API with the response data when it is ready, instead of making the Mule application wait for a long time or poll for a response repeatedly.

Haha, imagine setting up a Scheduler to check the external API every minute for 24 hours. That's going to be one busy Mule app!

I'm a little worried about Option A. Waiting for a response from an API that could take 24 hours seems like it could cause issues. Better to use an asynchronous approach.

I'm not sure, but option D seems interesting as it involves setting up an HTTP callback API in Mule.

I disagree, I believe option C is better as it allows us to invoke the API asynchronously and wait for the response.

Option D is interesting, but it would require coordinating with the external system to set up the callback. Might be more work than just using an Async scope.

I'm not sure about using a Scheduler to check for a response every minute. That seems like it could get messy and inefficient. Exposing a callback API might be a cleaner solution.

Option C looks promising, using an Async scope to handle the long-running external API call. That way, Mule won't be blocked while waiting for the response.
