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?

Universal Containers (UC) is currently managing a custom monolithic web service that runs on an on-premise server.
This monolithic web service is responsible for Point-to-Point (P2P) integrations between:
1. Salesforce and a legacy billing application
2. Salesforce and a cloud-based Enterprise Resource Planning application
3. Salesforce and a data lake.
UC has found that the tight interdependencies between systems is causing integrations to fail.
What should an architect recommend to decouple the systems and improve performance of the integrations?

A company's cloud-based single page application consolidates data local to the application with data from on premise and 3rd party systems. The diagram below typifies the application's combined use of synchronous and asynchronous calls.

The company wants to use the average response time of its application's user interface as a basis for certain alerts. For this purpose, the following occurs:
1. Log every call's start and finish date and time to a central analytics data store.
2. Compute response time uniformly as the difference between the start and finish date and time - A to H in the diagram.
Which computation represents the end-to-end response time from the user's perspective?

What are the two considerations of Apex REST services that an integration architect should keep in mind when building custom integrations?

A company needs to be able to send data from Salesforce to a home grown system behind a corporate firewall.
The data needs to be pushed only one way and doesn't need to be sent in real time. The average volume is 2 million records per day.
What should an integration architect consider when choosing the right option in building the integration between the external system and Salesforce?
