Refer to the exhibit.

What required changes can be made to give a partial successful response in case the United Airlines API returns with a timeout?

Show Suggested Answer Hide Answer
Suggested Answer: D

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.

Wait, can we really set the payload to 'Error'? That feels off.

I feel like using Flow Reference components could be beneficial, but I can't recall if they should be inside a Try scope or not.

I think we practiced a similar question where we used On Error Continue to set a default payload. It might apply here too.

The Scatter-Gather component could be useful here, but I'm not sure if that's the best approach. I'll need to weigh the pros and cons of the different options before deciding.

Okay, I think I've got this. The key is to use a Try scope and handle the timeout error properly. I'll go with option C, that seems like the most complete solution.

The question is asking about the function of the White list component, so I'm guessing it has something to do with managing or controlling access to the Orchestrator. I'll go with option D, which mentions an initial security check.
