Question 1

A company accepts payment requests 24x7. Once they accept a payment request, their

service level agreement (SLA) requires them to make sure each payment request is processed

by their Payment System. They track payment requests using a globally unique identifier created at the Data Entry Point. Their simplified flow is as shown in the diagram.

They encounter intermittent update errors when two or more processes try to update the same Payment Request record at the same time.

Which two recommendations should an integration architect make to improve their SLA and update conflict handling?

AMiddleware should coordinate request delivery and payment processing.

BData Entry Point and Middleware should automatically retry requests.

CPayment System should process a payment request only once.

DPayment System and Middleware should automatically retry requests.

BUse External Services feature to integrate gateway to Salesforce ensuring real-timeupdates the CSR and support post payment processes.

CMake a callout to the payment gateway through ESB supporting error handling andlogging for audit purposes.
