Exam Certified Integration Architect topic 1 question 92 discussion

Idempotency ensures that even if an order is sent multiple times (due to network issues or retries), it will only be processed once. Latency is a crucial factor in order processing integrations. Understanding the acceptable latency helps in designing the right integration pattern (e.g., real-time vs. batch processing).

now I like A&C more - order fulfillment is always near real time.

I think this one is B&D A: Already moving down a solution path of Outbound Messaging, when the question doesnt even start to look that way. There are so many other integration options, so to me you need to start high level and work your way down B: This is important because if Salesforce needs to validate addresses, that could bring in an additional integration effort to get shipping addresses validated, or perhaps in a project context it can be ignored because the fulfillment system will handle it. C: Not C because best practices dictates that this should always be the case D: Latency is always part of a business SLA, and is critical to understand what solution you will propose that is acceptable to the customer
