Câu 1: Salesforce Certified Integration Architect

A company is designing a Lightning Web Component (LWC) to display transactions aggregated from different sources. Their current system landscape is as follows:1. Transactions are created at any time through their various on-premise and cloud-based systems.2. All necessary transactions are replicated to a custom Transaction object in Salesforce. It is updated periodically so it only has a subset of the necessary transactions between updates.3. Middleware supports publish-subscribe interactions and provides RESTful Enterprise APIs that can retrieve transactions from on-premise and cloud-based systems. The company wants to address a usability concern regarding incomplete data displayed on the LWC component. What should the integration architect specify so the LWC will be able to display all the required transactions?

1. A. Publish a Platform Event, have the middleware subscribe and update the custom object on receipt of Platform Event.
2. B. Call the Enterprise APIs directly from the LWC's JavaScript code and redisplay the LWC on receipt of the API response.
3. C. Use the Continuation class to call the Enterprise APIs and then process the response in a callback method. — đáp án hiện tại
