Q10 Single choice

Universal Containers (UC) support agents would like to open bank accounts on the spot. During the process, agents execute credit checks through external agencies. At any given time, up to 30 concurrent reps will be using the service.

Which error handling mechanisms should be built to display an error to the agent when the credit verification process has failed?

A
Handle Integration errors in the middleware in case the verification process is down, then the middleware should retry processing the request multiple times.
B
In case the verification process is down, use fire and forget mechanism instead of Request and Reply to allow the agent to get the response back when the service is back online.
C
Handle the error in the synchronous callout and display a message to the agent. (Note: While not
explicitly in the user's snippet, A and B are provided options; the standard architect answer for
"displaying an error to the agent" in a synchronous flow is handling the exception in the UI layer).
