Question 8/51
Universal Containers (UC) currently owns a middleware tool and they have developed an API-led integration architecture with three API tiers. The first-tier interfaces directly with the systems of engagement, the second tier implements business logic and aggregates data, while the third-tier interfaces directly with systems of record. Some of the systems of engagement will be a mobile application, a web application, and Salesforce.
UC has a business requirement to return data to the systems of engagement in different formats while also enforcing different security protocols.
What should an Integration Architect recommend to meet these requirements?

This is so subtle and not easy, but the answer has to be A.
First the requirement is about the formating and security for the data coming into systems of engagement. ( not going out) . So the way its done is like this
Consider a Synchronous request call from Systems of Engagement ( Mobile UI) to System of Record ( Lets say Oracle) to get Orders. The flow will be ideally like this
Request :
Systems of Engement ---> (API Gateway Policies) ---> Experience APIs ( Tier 1) --> ( Api gateway policies) Process APIs ---> ( API Gateway policies) --> System API --> System of record
Response : ( IN the same context and thread of the request)
System of record --> System API ---> Process API --> Experience API -->(THIS IS THE PLACE WHERE THIS QUESTION ASKS FOR DATA FORMATTING AND SECURITY) System of Engagement..
So there is no API gateway calls while going back.
